I owe so much to Dr Theodorou. We spent loads of time in research finding the right consultant and clinic for us, and I'm so pleased to say we chose correctly. He understood immediately that I wanted to give IVF everything I had on the first go without sacrificing my mental health, body, or finances. He helped me find the right balance of testing and treatment and really tailored everything to me. Because of his careful and kind manner, I was successful on my first and only cycle of ICSI. My son is now 5 months old, and I honestly still can't believe it's real.

Thank you so much for your incredibly kind words. It truly means a great deal to me that you took the time to share your experience and that you trusted us after putting so much thought into your decision. I’m so pleased we were able to find the right balance for you and tailor your treatment in a way that felt both focused and manageable. Hearing that you were successful on your first ICSI cycle — and that your son is now 5 months old — is truly wonderful. Wishing you and your family every happiness.
Some people change your life forever and Dr Theodorou was one of them. We cannot recommend Dr Theodorou enough. He is highly skilled, kind, and genuinely caring, always taking the time to support and reassure me with my treatments. Communication with Meghan was seamless and always helpful. Anyone on a fertility journey would be in the best possible hands we were fortunate to welcome two beautiful children under his care. May you be truly blessed in this lifetime

Thank you so much for your incredibly kind and generous words. I’m deeply humbled by your trust and grateful to have been part of your journey. It means more than I can express to know that our care and support made a positive difference for you. I’m also delighted to hear your kind mention of Megan—I’m very fortunate to work alongside such a dedicated team. Welcoming your two beautiful children into the world is truly a privilege, and we wish your family continued health and happiness.
We are absolutely thrilled to share our experience with Dr. Theodorou and his phenomenal team. After a challenging IVF journey, we were overjoyed to announce the arrival of our beautiful baby boy in April! We couldn't be more proud of ourselves, and eternally grateful to Dr. Theodorou, his wonderful secretary Megan who’s kindness and efficiency never went unnoticed , and all the staff who supported us every step of the way. From our very first consultation, Dr. Theodorou demonstrated an unparalleled level of expertise, empathy, and dedication. He took the time to explain his purposed treatment, answered all our questions with patience, and made us feel truly heard and understood. His calm demeanour and reassuring replies to our emails were a constant source of comfort during what was a very emotional process. We wholeheartedly recommend Dr Theodorou to anyone seeking fertility treatment. He is not just a doctor, but a true miracle worker and he made our dreams of becoming parents true.
Dr Theodorou was patient, kind and knowledgeable. Our situation wasn't particularly straightforward but his advice and expertise meant that we were successful. We are very grateful to him for everything.
I just wanted to thank Dr Efstathios Theodorou for a great consultation, he was very kind and helpful in explaining everything to me and put me at ease
5 stars is not enough for Dr. Efstathios! After years of unexplained infertility and unsuccessful treatment at another clinic, we were overjoyed to welcome our baby boy earlier this month. Recommended by a friend who had successful IVF treatment under his care, we traveled from Spain for the opportunity to work with him. He was incredibly patient and kind. When we faced challenges with egg and sperm quality, he swiftly adjusted our treatment plan, which ultimately led to our successful pregnancy. His team was incredibly supportive throughout the entire process, always available to answer our questions and ease our anxieties. We are forever grateful to him and his team for giving us the gift of parenthood. We highly recommend him and his team to anyone facing infertility challenges
We are deeply grateful to Mr. Theodorou for his exceptional care. He is an excellent and highly knowledgeable physician who is clearly passionate about providing outstanding patient care. Above all, he is approachable and takes the time to explain everything in detail, ensuring that patients feel fully informed and supported throughout their journey. A special mention also goes to his secretary, Megan, who is incredibly responsive, kind, and accommodating, making the entire experience even smoother.
Excellent in every respect- really kept me calm during embryo transfer
Dr Theodorou was excellent throughout our treatment, he managed our expectations (age was not on my side) after 2 IVF treatments and only 2 embryos making it through genetic testing we had a successful transfer. Our baby boy is now 4 months old. Dr Theodorou and the wider team thank you is just not enough.
Dr Theodorou was professional, thoughtful and always prepared when we had our consultations. We always felt informed and at ease whilst going though a difficult process. I would recommend Dr Theodorou and CRGH. Megan (Dr T’s secretary) and all the nurses are great and all questions and concerns were dealt with promptly throughout our journey.
