THEY ARE AMAZING!!! I absolutely love this clinic and everyone who works here! Being a lesbian couple, we were nervous trying to find a fertility clinic for us.. they made us feel so comfortable right away! They are so caring and sweet! I definitely recommend this place!! && Dr. Z is the man!! Nicest doctor I have ever met! I would give them a 100 stars if I could!
Thanks to Dr. Dudley, we achieved a successful pregnancy, a dream that once seemed unattainable. His expertise and empathy made him not just a doctor but a beacon of hope in our most challenging times. We are profoundly grateful to Dr. Dudley and highly recommend him to any couple facing fertility issues!
We've worked with RGI twice now, and have had an excellent experience both times. Dr. Maseelall and her team have been amazing to work with. This time around, we were introduced to the "navigators" who essentially act as a liaison between us and the doctors, which was a change from the last time we were there. We found having access to a dedicated resource - even by text message - was a huge plus.
I highly recommend Dr. Dudley! He is one of the only doctors who explained things clearly, realistically, and positively. His bedside manner is outstanding. A defining moment (without disclosing my medical history) was when I explained something to him and he responded with "I believe in a women's intuition." He believed me, ran a quick test, and pivoted the plan. I can't recommend him enough.
My husband I went to Dominion after struggling with some fertility issues and multiple miscarriages. We couldn't have made a better choice! You can tell that the staff really care about their patients and make you feel at ease. At the beginning of the process, we were feeling a bit overwhelmed, but the doctors were understanding and great at explaining each step to us along the way. We now have a healthy baby boy and we could not be more happy and grateful to Dominion Fertility!!
