Dr. Alin is exactly what the country and patients with endometriosis needed, the best diagnostician and the only one in the country who uses protocol-type ultrasound, with which he can also see other organ damage. A true professional surgeon! I hope you stay here in the country!

A doctor you rarely find! He pays close attention to the ultrasound examination and provides the necessary explanations! What others saw on the MRI, he saw dancing on the ultrasound. Grade 20!

I wish all doctors were as attentive, humane and supportive as Alin Constantin! In addition to dedication and professionalism, he also has a calmness and empathy that generates trust! He helped me a lot to investigate the problems with menstrual pain and calmed me down a lot in the moments when I thought there was something wrong with me!

One of the best endometriosis specialists I ever came across! Dr Constantin recognises symptoms that others miss and really takes the time to explain the complexities of endometriosis and also adenomyosis. Can absolutely recommend him!

A doctor I recommend with all confidence! I had surgery by the doctor and, throughout this process, I felt that I was in very good hands. He is an empathetic, attentive and involved doctor, who listens to his patients, patiently answers questions and takes into account their needs and fears.

🌸 A Doctor Who Truly Goes Above and Beyond — Dr. Alin Constantin 🌸 There are doctors who treat you, and then there are doctors whose care stays with you long after you leave the hospital. Dr. Alin Constantin is one of those rare doctors. On 23 September 2025, I underwent a 7-hour surgery for deep infiltrative endometriosis (DIE). Dr. Constantin and his team persevered through those long hours and did not give up on me. His expertise, dedication, and commitment during one of the most difficult moments of my life are something I will never forget. But what makes my gratitude even greater is that his care did not end with the surgery. Even now, Dr. Constantin continues to check up on me and genuinely cares about how I am doing. He remains easily accessible whenever I have questions or concerns, which gives me an incredible sense of reassurance. Knowing that I can reach my doctor and that he continues to care about my recovery means more than I can put into words. For someone going through endometriosis, having a doctor who listens, takes you seriously, fights for you, and remains present throughout your recovery is priceless. Dr. Constantin, thank you for not giving up on me. Thank you for your exceptional medical care, your humanity, your accessibility, and for continuing to look after me even after the operation. I will forever be grateful that I was placed in your hands. 🙏💗🌸 #DrAlinConstantin #Endometriosis #DeepInfiltrativeEndometriosis #DIE #EndometriosisAwareness #EndometriosisSurgery #Gratitude #WomensHealth

Dr. Constantin is an excellent doctor — professional, kind and very thorough. He takes the time to listen and explain everything clearly, and I felt completely at ease throughout. I would definitely recommend him.

A doctor who impresses not only with his professionalism and training, but also with the way he knows how to be with the patient. Dr. Alin Constantin is a young doctor, with a remarkable professional background, but also a warm, cheerful and empathetic man. He makes time for each patient, listens carefully and explains everything with patience and clarity. A doctor who inspires confidence and whom I highly recommend!

Dr. Alin Constantin is a special doctor and a MAN, professional, calm and empathetic. He has a careful and clear approach, explains patiently and conveys security, including in difficult situations. I appreciate the fact that he chose to bring to Romania the experience and know-how acquired abroad. A doctor you can trust and whom I recommend without hesitation, especially to patients dealing with deep endometriosis.

There are people you meet at a difficult time in your life and you never forget them. For me, Dr. Alin Constantin is one of those people. I have been going to the gynecologist since I was 14. Today I am 37. In all these years, I have gone through countless consultations, check-ups and investigations, but no one has been able to discover the problem I had. Years in which I lived with symptoms that, at one point, I had almost come to consider normal. Then I came to Dr. Alin Constantin. For the first time, I felt that someone was not just consulting me, but really listening to me and trying to find the explanation behind what I was feeling. I finally received a diagnosis and, with it, answers to things I had been carrying with me for many years. I underwent a complex intervention for endometriosis, and the way the doctor managed both the medical part and the relationship with me as a patient gave me enormous confidence. He explained, was patient, was present and gave me that feeling of security that you need so much when your health is in someone else's hands. Beyond professionalism, I met an empathetic, calm and involved man. A doctor who cares about the person in front of him, not just the diagnosis. When you think that 23 years have passed since my first visit to a gynecologist until someone managed to identify the problem, it is difficult to express in a few lines the gratitude you feel towards the man who finally gave you an answer. I am deeply grateful to Dr. Alin Constantin for everything he has done for me and for the chance to start a new chapter, with more peace of mind. I recommend him wholeheartedly to any woman who is looking for not only an extraordinary doctor, but also a man she can trust. Thank you, Dr., for everything!

The doctor gave me the correct diagnosis, quickly, in an extremely delicate and borderline situation, after I was exposed to several negative scenarios from other doctors, and he managed to restore my confidence that things would be resolved. In addition to his obvious professionalism, he is also a very empathetic doctor who is there for the patient.

I can’t recommend Dr. Alin Constantin enough, especially for anyone dealing with endometriosis. After years of feeling dismissed by other doctors, it is such a relief to find a gynecologist who actually specializes in this condition and takes it seriously. Dr. Constantin is incredibly thorough during the consultation, takes the time to explain everything clearly, and never makes you feel rushed. It is obvious this is an area of real expertise — the depth of knowledge about endometriosis specifically makes a huge difference. The treatment plan is personalized rather than generic, and you can feel truly listened to. If you’re struggling with endometriosis and need a specialist who genuinely understands the condition, I highly recommend Dr. Alin Constantin.

I recommend it with all confidence.

Translated by Google

I highly recommend Dr. Alin Constantin, one of the few endometriosis specialists with a very extensive case history. His training abroad and experience in the field are evident from the first interaction. In my case, he immediately identified that certain diagnoses previously made by other doctors were wrong and put things in their true perspective. I greatly appreciated his calmness, empathy and willingness to answer questions. He does not make you feel treated superficially, but listened to, understood and safe. I sincerely recommend him, from my own experience.

After more than 6 years of suffering with very heavy menstruation, fainting spells and days when I could no longer leave the house because of my menstrual flow, after changing doctors and trying numerous treatments, I ended up consulting with Dr. Constantin Alin, at Monza Hospital. My experience was completely different. I met an extremely empathetic, calm and attentive doctor, who explains everything to you in a way you can understand and is patient in answering every question or concern. For me, after so many years of dealing with this problem, the fact that I felt listened to, understood and treated with respect meant a lot. He is a doctor who gives you confidence and security and who, from my point of view, puts the person and their needs above all else. I am grateful that I came to him and I recommend him with all confidence!

I am grateful that I came to see Mr. Alin Constantin. I found in him a doctor you rarely meet: empathetic, attentive, patient and, above all, truly involved in helping his patient understand what is happening to his own body. The consultation lasted about an hour and was one of the most detailed consultations I have ever had. He explained everything clearly, in my understanding, patiently and without making me feel like I was asking too much. I left there with joy in my soul and with the feeling that I had lost: that, finally, someone listened to me and explained to me what was happening to my body. Every time I had questions, he took the time to answer me. For me, this means a lot. After an unpleasant experience following an intervention, Mr. Dr. Alin Constantin is the doctor who made me trust a doctor again. And for that I am sincerely grateful to him. I wholeheartedly recommend him to all women who are dealing with endometriosis and are looking for not only a very well-trained doctor, but also a man who will listen to them, explain to them and give them confidence. With all my respect and gratitude, Dr. Alin Constantin, thank you! ❤️

I recommend with all confidence and respect Dr. Alin Constantin!!! I really appreciated his attention to patients, his patience and professionalism. I had surgery with Dr. Alin at Monza Hospital in Bucharest 2 months ago for endometriosis and adenomyosis, the surgery went wonderfully thanks to his experience, patience and empathy. An attentive, involved doctor and an extraordinary man, I recommend him with all my heart.

I wholeheartedly recommend Dr. Alin Constantin. I came to him with a uterine fibroid of approximately 14 cm and a more complicated case, being also a pacemaker wearer. The surgery took place in April, it was a complex laparoscopic myomectomy and lasted approximately 5 hours. For me, it was very important that the intervention was done taking into account my desire to be able to carry a pregnancy in the future, and the doctor respected this fully. What I greatly appreciated was that he chose the right approach for my needs as a patient, not the option that would have been simpler or more convenient for him, even if that meant a very difficult intervention. Last month I had a post-operative check-up and everything is very good, which makes me even more grateful for the choice I made. In addition to professionalism and competence, he inspired a lot of security and trust in me from the beginning. I felt like I was in the right hands with the right doctor and if I had to choose again, I would choose him without any hesitation. I am deeply grateful to him and I recommend him with all confidence. ❤️

I have known Alin for a long time and he is one of the doctors whose professionalism I have great confidence in. He is extremely well-trained, rigorous and attentive to every detail, with very high standards in terms of medical practice. He takes his job seriously, is constantly concerned with being up-to-date and has the experience and discernment necessary to manage even difficult cases. Beyond all this, he remains a balanced, calm and attentive man with his patients. I think he is the combination you look for in a doctor: competence, seriousness and humanity. I recommend him without any reservations.

I came to Dr. Alin Constantin after two months of trying to find the cause of pain that was driving me to the brink of fainting, after an MRI that didn’t justify the intensity of the pain and all the symptoms I was having, and after a month of hormonal treatment that I felt was doing more harm than good. I had quite a lot of hope that I would finally receive an answer and validation, following what I had read about the doctor. However, in my heart there was a struggle between “What if it’s all in your head?” and what I was really feeling, physically. As a patient with endometriosis and adenomyosis, who went to many doctors in an attempt to find an answer for some real and disabling pain, it is extremely important to be listened to, to be believed, and to feel that the doctor is trying to understand what your body is telling you. It is also important not to be offered treatments that scare you or that, to a certain extent, contradict what you are feeling. During the consultation, I felt validated, listened to, and respected. I felt that the doctor empathized with me and that I didn’t need to constantly try to justify my symptoms. I was believed. And all my symptoms matched a new diagnosis: adenomyosis. They weren’t “just in my head.” It was the first time in months that I left a doctor’s office with a clear answer to all my questions, with a diagnosis that explained what I was feeling, and, above all, with the hope that I would be well and that I would be able to find my balance again. A few days after the consultation, I had a question, and as the doctor advised me to do in case of questions or problems, I wrote him a message. I was hoping he would answer me, but I was surprised when I saw that he was calling me. And his first words were: “How are you?” It's been two years since I was diagnosed with endometriosis, after another three years of trying to find answers to the pain that paralyzed me during my period. In those years, I went through two surgeries, hospitalizations and visits to the Emergency Room that had become almost regular, in my desperation to be well, as well as dozens of consultations with doctors of different specialties. But it was the first time a doctor told me to listen to my body and trust what I was feeling. I was shocked. Maybe this is how a conversation with a doctor should be when you have endometriosis and adenomyosis, but I was not used to such answers. Until the endometriosis diagnosis, I had heard, too many times, "That's not true," when I said that I didn't feel well under a certain hormonal treatment, or even "You are not capable of enduring the excruciating pain of menstruation," said by a maternity psychologist after I was hospitalized after fainting at work. For all those who suspect they may be suffering from these diseases, I encourage them, as I was encouraged by the doctor, to trust what their own body is telling them and, above all, to find a doctor who does not minimize their symptoms, symptoms that can profoundly affect our lives and bring us to the brink of despair. When I left the doctor’s office, my family and friends were waiting for a response. And among the first messages I sent was: “I found my gynecologist.” I know that my struggle with endometriosis and adenomyosis continues, but I am deeply grateful for the peace and hope I received. For the first time in a long time, I left a doctor’s office with the feeling that I would somehow manage to find my balance and have a normal life again.

I came to Dr. Alin Ștefan Constantin after reading several recommendations and experiences of patients in several groups, trying to find a doctor who I felt was right for me… and I think it was one of the best decisions I have ever made. For me, as a person with an anxious profile, it was very important to find a doctor who would be patient to answer all my questions, who would be patient to know my entire medical history, to explain things to me in a way that I could understand, and, above all, not to feel like I was rushed or asking too many questions. I left the consultation with the feeling that I had been listened to and that I understood why I was doing the treatment I was doing, and that gave me a lot of confidence in his approach. The consultation was very well documented and attentive, the most detailed consultation on this profile I had had up to that point. But beyond the medical side, it meant a lot to me to feel supported and in good hands. I am undergoing treatment for endometriosis and I feel much better… it is absolutely amazing and extraordinary to simply start living with less pain. A sincere recommendation, from my experience, for a doctor who has given me back not only hope that things can get better, but also confidence in the process. ❤️

I came to Dr. Alin Constantin after asking people I trusted to recommend a gynecologic surgeon who could help me with very heavy menstrual bleeding and a uterine fibroid. From our first consultation, I appreciated his structured and thorough approach. He recommended additional reproductive medicine investigations and clearly presented 3 treatment options. I went through all the necessary steps and had the information I needed to make an informed decision about the best treatment for me. I particularly valued the fact that I was given real options rather than being pushed toward a specific intervention. I ultimately underwent a laparoscopic uterine myomectomy. The surgery and the medical care throughout my hospitalization went exactly as expected. I was continuously informed about the protocol and what was happening at each stage. I should also mention the excellent conditions and medical staff at Monza Hospital, a 10/10 experience. My recovery after surgery followed exactly the course Dr. Constantin had described beforehand. My part was simply to follow his instructions and give my body the necessary time to heal. At my first postoperative check-up, I was extremely happy with the results. The surgical outcome was excellent and my body recovered as expected. Further follow-up appointments are planned over the coming months. Most importantly, my menstrual cycle is now normal and I can enjoy my life again. I recommend Dr. Alin Constantin with complete confidence. For me, the medical standard, professionalism, communication and quality of care were exceptional.

I highly recommend Dr. Alin Constantin for his professionalism, attention, and the way he makes you feel safe. A doctor I trusted from the first consultation.

A doctor who really listens After years of feeling like my symptoms weren’t really heard and my pain was ignored, meeting this doctor made a huge difference. He was the first doctor who really listened to me, without minimizing what I was feeling or telling me “it’s normal.” He put my symptoms, history, and tests together and diagnosed me with endometriosis and adenomyosis. Maybe for a doctor, a diagnosis is part of the job. But for a patient, the moment someone finally tells you “I believe you and there’s an explanation for what you’re feeling” can mean a lot. Sometimes, the first step to a correct diagnosis is simply having a doctor who takes you seriously. I highly recommend it! 🤗

An extraordinary doctor, both professionally and personally. He is an endometriosis specialist who combines medical knowledge and experience with a lot of empathy and patience. What I appreciated the most is the fact that he really listens to his patients, understands them, gives them the time and attention they need and explains everything in a way that they can understand. In a field where many patients come after years of pain, uncertainty and frustration, it is extremely important to find a doctor who not only treats the disease, but also sees the person in front of him. He is the kind of doctor who gives you confidence and the feeling that your problem is really important to him. I highly recommend Dr. Alin Constantin to all patients who are dealing with endometriosis and want not only a very well-trained professional doctor, but also an empathetic, attentive and involved one.

After meeting doctors who, over time, made me feel that my pain was ignored or minimized, meeting the doctor was a real change. He is, without exaggeration, one of the most attentive, empathetic and caring doctors I have met. He listens, explains, is patient and, most importantly, makes you feel that you are seen and understood not just because you have a diagnosis. In endometriosis, where the road is long and difficult, it is extremely important to have a doctor by your side who sees not only the disease, but also the person in front of him. I am grateful that, after so many experiences in which I felt neglected, I finally met a doctor who treats with seriousness and professionalism plus a lot of empathy. A truly involved, attentive and dedicated man to his patients. I recommend him with all my heart and thank him for the way he takes care of me!
