What Patients Are Saying About Dr. Styer

“I came to CCRM as my “third opinion” clinic. After suffering from an ectopic and multiple failed transfers that left me with no remaining embryos. From the minute I sat with Dr. Styer for my consultation, I knew if anyone could help me it would be him. He was very transparent about what he would do differently and felt confident he could make this work. More than his words, his calming demeanor put me at ease. I knew when I left that appointment I was switching clinics, despite the clinic being an hour plus drive from my home. What I didn’t know was how much I would hope I had started my journey with CCRM. My egg retrieval with CCRM produced the same number of mature eggs as my last clinic. However, I got 3x as many embryos and all but one of those embryos was genetically normal. I can remember crying when I got the news. Along the way, Dr. Styer never made me feel badly for asking a million questions. As we prepared for transfer, my nerves began to show up. We transferred one embryo and for the first time, I was pregnant with a uterine pregnancy! Now what’s more amazing than that news? The fact that Dr. Styer delivered the news to me himself via phone on his weekend off on a Sunday morning! I’ll never forget this call for the rest of my days. In addition to having an amazing physician, the clinical staff at CCRM Boston is amazing. I had personalized attention from several nurses (Roisin, Katie, Maryann and Kristen). When I walked in for an appointment, EVERYONE wanted to know how I was doing and how they could help. I’ve never felt more cared for in any medical setting in my life. I could not possibly recommend CCRM more highly – Dr. Styer and his team made my life long dream come true.”

“My wife and I were really frustrated by another other facility’s inefficiencies and their lack of sensitivity to our needs as a married female couple. We were recently referred to Dr. Styer by one of our friends who was his prior patients. From the first minute, Dr. Styer really made us very comfortable with his gentle manner, sense of humor, and expertise in LBGT fertility care. We just found out we are pregnant with our most recent IUI!!! So excited and thankful for Dr. Styer and his team!”

“My wife and I had the great pleasure of meeting Dr. Styer a few months ago to help us get pregnant. We are both in the healthcare field and we can easily say that our care at CCRM has been the best we have experienced as patients and as healthcare providers. Dr. Styer has a knowledgeable, compassionate, and thoughtful bedside manner that is truly refreshing. He and his team always made time for us if we had additional questions and always made us feel so comfortable. The clinic and staff were so welcoming and our care has been top notch. The fertility journey has been challenging for us over the past few years. However, Dr. Styer has truly shown us what is means to “care” for patients. He has been so enthusiastic and our confidence in our chances for pregnancy have been bolstered immensely. His care of us has been second to none. He is an incredible fertility doctor and we recommend him and CCRM to anyone who is looking for a clinic where you want truly excellent care.”

“I came to Dr Styer after 2 failed IVF cycles with another clinic. I got pregnant on the first attempt with Dr Styer. Aside from the positive result, Dr Styer restored a lot of lost confidence that had been gone for a long time in the brutal IVF process. At times he felt more like a therapist than a doctor, talking me through every step of the journey and being incredibly sympathetic when I felt hopeless or anxious. I remember getting my last ultrasound with him when I was 6 weeks pregnant, and feeling nervous that I may not ever receive that level of comfort and care from a doctor again! Dr Styer is truly the best for fertility. 5 out of 5.”
