“Dr. Peck helped us with our embryo implantation and she was the best! Not only did she explain every step and communicate with ease, she was also friendly and accessible. When we had a little scare, she was available to reassure us and comfort us and she made sure all the conditions were optimal for our implantation. Without her we wouldn’t have our beautiful and healthy eight month old boy- thank you infinitely Dr. Peck- you gave us the greatest gift and you do so with professionalism and positivity! Reader- please know that you are in great hands with Dr. Peck.”


>”To say Dr Peck is an AMAZING doctor, that is an understatement.  My husband and I had been trying to conceive for 5 years.. after many. many, many ups and downs of would parenthood be in our cards a friend referred me to Dr Peck to do initial meet and possible tests. Of course going into the appointment I didn’t know what to expect I was so nervous. But the moment I sat down in her office she instantly made me feel at home, she is so down to earth, honest and overall such a sweet person. After leaving the appointment I called my hubby and was so excited to try IVF. Throughout the entire process she was open, committed and available for whatever questions and concerns I had. Her coordinator Kimberly is AWESOME!! And because of that, we now have our 4month old son. We owe them beyond words and are so blessed to have started our family. And when the time is right we are definitely wanting to try for our 2nd with her. If you are thinking of IVF…make an appointment with Dr Peck, you wont regret it!!”


“How can I write a review for someone who literally changed the course of my life?!  I went to HRC since they were covered by insurance, and pretty much stumbled upon what would become one of the best decisions of my life. I went to see Dr. Peck in March of 2017 and immediately was drawn to her kind and genuine personality, along with her calming manner of explaining the IVF process. She would always stop me from getting TOO ahead of myself, and would encourage me to focus on the next step so that I didnt get overwhelmed.  WHAT A GREAT APPROACH, particularly with someone of my over-analytical personality.

Flash forward a few months and we were retrieving eggs.  My case was a bit more complicated than your average because I also had fibroids that were basically a huge, if not sole contributor to my not getting pregnant.  Dr. Peck carefully devised a plan in which we would retrieve the eggs, create the embryos and then remove the fibroids a bit before we implanted.  The fibroid removal was going to be a bit of a gamble because if it didn’t work, I would have to go in for a full on myomectomy and recovery would have been 6 months before I could do an implant…well, needless to say, Dr. Peck came through and got the fibroid out for me! The clock was ticking on when if/when it would grow back, so we went straight into implant phase. I hear that some doctors are apprehensive about putting in 2 embryos, but Dr. Peck was supportive and even encouraging after assessing my case. We did it…the chances of getting twins was something like 15% and the chances of just 1 embryo attaching was much higher at something like 65-70%. And here I am 2 years later with beautiful boy/girl twins!! Dr. Peck made my dreams come true…even the dream that I never even knew I had. I was nervous to even have 1 kid much less 2 kids, but it was truly God’s blessing and Dr. Pecks incredible instinct and talent that put me in this position. I am just eternally grateful for Dr. Peck and her nurses. Dr. Peck brings amazing bedside manner and I truly believe this is her purpose in life – to help women get pregnant and bring beautiful lives into this world.  Thank you, Dr. Peck!!!!!!!”
