Dr. Pena is awesome. From the beginning, he was kind, thoughtful, and supportive throughout the entire IVF process. He takes the time to explain everything thoroughly, making sure you feel informed and comfortable through every step. He is super responsive and always gets back to questions quickly,.The entire process felt smooth and positive. I’m grateful for his care and would highly recommend him to anyone considering IVF.
Dr. Pena and his entire team have been an incredible source of support during one of the most challenging journeys of our lives. IVF is not an easy road — emotionally, physically, or mentally — but from the very beginning, we felt informed, cared for, and truly supported every step of the way. Dr. Pena takes the time to explain options thoroughly and thoughtfully, including discussing pathways such as embryo adoption, which made us feel empowered and never pressured. He approaches care with both expertise and compassion, which makes all the difference when navigating something as personal as fertility treatment. What also stood out to us was how included my husband felt throughout the entire process. So often fertility care can feel focused on one partner, but Dr. Pena and his staff made sure we both felt heard, involved, and respected as equal parts of the journey. The office staff deserves special recognition as well. They are kind, organized, and incredibly responsive — emails and phone calls are returned quickly, which provides so much reassurance during an already stressful time. Knowing we could reach someone and get timely answers eased a lot of anxiety. We are deeply grateful for the care we received and would highly recommend Dr. Pena and his team to anyone navigating fertility challenges. Their professionalism, compassion, and responsiveness truly set them apart.
From the first day my husband and I met Dr Pena and his whole staff, they have been so fantastic. I always felt a strong sense of kindness. They are patient and willing to answer any question, at any time. During my time at RMA, I mainly was under the care of Dr. Pena, Alexis and Jess and I couldn’t be more pleased! RMA was the first fertility office I went to, and knew it would be the one for me! Dr. Pena was very informative during my first meeting. Since then, I maintained confident that he would make me and my husband’s dreams come true. I highly recommend Dr Pena and the whole staff at RMA!!
I did not know much about infertility and IVF/FET. Dr. Pena is very knowledgeable and explained everything so I would understand it. Everyone in his office was amazing and so friendly! They made me feel super comfortable, would answer any question I had (even the ones I thought might sound ridiculous asking, they never questioned it) and would respond back to phone calls or emails promptly. Dr. Pena and his staff were extremely helpful and supportive. We cannot thank them enough for helping us start our family. We are extremely grateful. Our son is a huge blessing. Dr. Pena and his staff have become our family and we are so thankful for them. We highly recommend Dr. Pena to anyone.
It is difficult to put into words the gratitude I feel for Dr. Pena and his entire staff. Their sincere and genuine interest in helping my husband and I start our family was evident from the time of our first visit. Dr. Pena's wealth of knowledge and vast experience consistently put me at ease during what could have been an emotionally grueling process. He is professional, personable, responsive, and reassuring. His nurses and office staff are among the warmest and most knowledgeable medical professionals I have ever met. I truly feel like part of the LI IVF family, rather than a patient. Dr. Pena helped us begin our family with a healthy, beautiful daughter and we look forward to continuing to grow our family soon, with his help. I am immensely grateful for the recommendation I received from a close friend (and now mother of three) two years ago. I recommend this practice wholeheartedly!
