He was trained in Athens and London. He holds a degree in fetal medicine, and his PhD thesis was in the field of genetics at Imperial College. A pioneer in fetal medicine, he founded the first fetal medicine unit in Greece, at Mitera Maternity Hospital, in 1991, a Panhellenic reference center for fetal ultrasound. He was also the first to introduce all the new prenatal fetal tests.

From 2001 he has been a professor of obstetrics & genetics at the University of West Attica, where he introduced the Obstetric Ultrasound course and was responsible for the undergraduate course for high-risk pregnancy.

Professor Petros Nikolaidis is the founder and chairman of “Embryoitriki-genetiki” in Maroussi, a leading fetal medicine and genetics diagnostic center that he set up in 1998. It expanded into a growing network of fetal and gynecological screenings in several cities. At the same time, he collaborated with State Maternity Clinics and sent his students for internships in hospitals throughout the country.

In 2017, Petros Nikolaidis became a certified doctor from the Alinsod Institute for the THERMIva®, a groundbreaking method of vaginal rejuvenation with radio frequencies. THERMIva® is a non-surgical feminine treatment for stress incontinence, overactive bladder, atrophic vulvovaginitis, orgasmic dysfunction, vulvar dystrophy, and modern management of menopausal symptoms.

They said about us

It has been verified. My children. My whole life. I thank my husband, the best father and husband I could ask for, my doctor Petros Nikolaidis, who once again helped me have a wonderful, normal and natural birth, my midwife Lambrini Pallikara who guided me again in such a way that I managed to enjoy every minute of this miracle…

Doukissa N., 2/10/2019

Thank you very much for the wonderful birth I had with you and your wonderful team. The only thing that is certain is that a worthy gynecologist does not resort to a cesarean section under any circumstances for this reason. Even if the umbilical cord is wrapped 4 times, as you took out my little angel. Thank you very much for everything… And for your contribution to Hope Genesis… Continue your incredible work..

Katerina K., 24/11/2019

It was a magical feeling. A wonderful VBAC. Knowing Mr. Nikolaidis’ vast experience in natural childbirth and having become pregnant again after 21 months, I decided to give birth naturally. I wanted to experience the arrival of my child with all my senses, to see his father look him in the eyes and cut the cord… If I hadn’t had the professor and Lambrini by my side, I might have hesitated. With them I lived the most beautiful experience of my life. And even though I have a little boy who is my whole life, when the baby took his first step to become independent from the womb, I felt that this is a relationship that is won from the first second!

I wanted to give birth naturally from the beginning, and as I searched, I ended up with Obstetrics Professor Petros Nikolaidis. We went to the hospital and I gave birth after 21 hours, the next night. Quietly, painlessly, naturally… The professor insisted on giving the body the time it needed for the birth to go smoothly and Lambrini, his midwife, prepared it with exercises and massages. In the final push that lasted just 10 minutes, the child slipped and came out without pain. A little girl 51 centimeters long and weighing 3,180. And then came another wave of humanity and medical care. The professor asked that I not be transferred to the recovery room… We stayed in the operating room, my husband, me and our child. I breastfed him and we hugged him, amazed by the miracle of life, and in those two hours, the three of us alone there bonded like a family! I will never forget this very personal interest and care of the professor and his team. We thank them from the bottom of our hearts!

Konstantina K., 29/7/2020

It was my first birth and it was completely painless and enjoyable. I gave birth very quickly. I entered Iaso at 12 with the expectation of giving birth around 1 pm, and at 9 am the little one came out waving… All this time my doctor Petros Nikolaidis and the awesome midwife Lambrini Pallikara never left my side for a moment, as if they were my family… I will never forget this warmth, the certainty of safety and humanity that was captured even in the video that my husband took, recording this awesome experience of a truly dreamlike birth that I wish every mother could experience.

Faea M., 4/10/2020

A year and a half ago we experienced a high-risk pregnancy with a very bad outcome. Our doctor, Mr. Nikolaidis, encouraged us for the next attempt. “It will be a Spartan pregnancy,” he told us. His insight and experience immediately discovered my thrombophilia and thus he made sure to shield the situation from the very first moment. At each of our visits we left reassured that everything was going smoothly as he has the ability to see the fetus with his eyes closed! On January 25, we brought our little angel into the world, a very healthy baby boy weighing almost 3 kilos. We are happy and blessed, not only because we experienced a wonderful pregnancy with him but in combination with our beloved midwife, Ms. Lambrini Pallikara, they helped us have a beautiful normal birth that we will remember forever with nostalgia!

23 years ago, I was sent from Samos to find obstetrician Petros Nikolaidis in Mitera. He had left and was in Iasos, which had just opened. They did not inform me and sent me to another doctor there. A wrong diagnosis, telling me that one of my little boys would be sick. In despair, I returned to the island. My doctor here at the time was in good health, he has now retired, he is a great man, he went all over the world to find him. When I learned that he had changed hospitals, I returned to Athens and began this wonderful journey with him that brought my two wonderful children to life. I may have lost him since then, but I have never stopped for a moment when I see my boys thinking of him and thanking God that he was in my path. I am very happy every time I hear a story about him. This shows that in addition to being a very good scientist, he continued to be a wonderful person. Once again, from the bottom of my heart, I thank you, my doctor.

THERMIva®. I did it!! Miraculous!!

Electra P., 23/4/2021

A huge thank you to my excellent doctor, Petros Nikolaidis… To the doctor of my heart who, together with the wonderful midwife Mrs. Lambrini Pallikara, I had a normal birth… A birth that I could only imagine in my dreams… Thanks to these two people, I gave birth painlessly and with great safety… I saw what it is like to be treated with such kindness and kindness that you leave yourself in their hands and enjoy your birth… After a difficult birth of the first child, the second one comes to show me exactly what a miracle of life is… You deserve many congratulations and well done… Keep up the good work you do, with the love you do it with… My doctor, you are the best and we love you…

Tell me, where would I be now without this man?

For two years I had some discomfort and the doctors were detecting a cyst in the ovaries, sometimes on the left and sometimes on the right. With this and with that, I got disappointed and gave up. Until I saw on the Internet that Mr. Nikolaidis had opened a clinic in our city. I visited him and after hearing my problem, he suggested: Let’s go and do a laparoscopy! This is not a cyst. So, fortunately, we arrived in time at the operating room, where he removed a huge appendicitis with borderline malignancy and now my life has changed. I walk, I move normally now and while waiting for the results of some tests, I am now starting to plan the arrival of a child without pain, discomfort and hidden syndromes that threatened my life!

Marina M., 5/3/2021

I had the best doctor, Petros Nikolaidis, to explain to us and help us make decisions, and the best midwife, Mrs. Lambrini Pallikaras. As for Konstantina, I love her so much… the security they provide you during pregnancy and during normal childbirth helps you overcome every difficulty and see everything optimistically… I love you and thank you from the bottom of my heart for everything.

Demeter P., 28/10/2021

We were going for a premature birth, except that it didn’t happen at all. We talked, we were informed, we felt familiar and, most importantly, confident, and when the time came, I went to the hospital as we had agreed with our doctor, Mr. Nikolaidis, and after 4 weeks our little girl was born in a very easy birth, completely normal and safe, a very healthy child (2,800) who after two days was at home…
