Bio
Joseph Peña graduated with a B.S. Degree in Biology, summa cum laude from Rensselaer Polytechnic Institute in Troy, New York. Recipient of the prestigious Roland Walker Prize for outstanding academic achievement and promise of a successful career," Dr. Peña received his medical degree from the New York University School of Medicine in New York. He completed his residency in Obstetrics and Gynecology at the esteemed oldest hospital in the United States, Pennsylvania Hospital in Philadelphia, where he also served as Administrative Chief Resident. Dr. Peña then completed his fellowship in Reproductive Endocrinology and Infertility at the prestigious Columbia University College of Physicians and Surgeons, where he so greatly impressed, he stayed on as faculty as Assistant Professor at the highly regarded Center for Women’s Reproductive Care at Columbia University before joining East Coast Fertility in 2004. Dr. Peña is board-certified in Obstetrics Gynecology and Reproductive Endocrinology/Infertility, and has numerous publications in peer-reviewed journals. For Dr. Peña, the field of reproductive medicine is a good day-to-day mix of office infertility practice, surgery, and reproductive endocrinology using the most advanced technologies to help patients resolve their family-building challenges. <strong> </strong><em><strong>In college I contracted Guillain-Barre Syndrome, a paralyzing autoimmune disorder. After six weeks in ICU and then a year-long rehabilitation, I realized that I was drawn to the field of medicine. Having been a patient myself, I know the importance of having a caring and competent physician.</strong></em>
