Why I Love Being A Fertility Doctor

“I decided to pursue fertility medicine because I was fascinated by the science and I just loved it. I did two electives at TRIO and after I graduated with my Reproductive Endocrinology & Infertility Fellowship, I was thrilled to join the team here at TRIO. As a fertility specialist, I love being able to offer people the opportunity to grow their families, either by assisting them with fertility treatments or by offering them alternative options to still live their dreams of becoming parents.
