“I love building connections with patients. I try to validate their feelings and reassure them; to tell them I will be there for them, that I’m on their team, and that we will work towards a solution together. It makes my day when I feel like I have built that connection, that I have made myself available to a patient, even if it’s someone I met just minutes earlier.”

My Journey in Medicine

The physician and alchemist Paracelsus once wrote, “Medicine is not only a science; it is also an art. It does not consist of compounding pills and plasters; it deals with the very processes of life, which must be understood before they may be guided.” As I completed my medical training, including residency in obstetrics and gynecology and fellowship in reproductive endocrinology and infertility (REI), I realized I wanted to spend my career not only treating patients in the clinical setting, but also attempting to understand the “very processes of life” as they affect reproductive physiology and disease. As an REI specialist, each patient encounter and research challenge represents a unique facet of a field I love.

My specialities within my field include fertility preservation, access to fertility services for LGBTQ+ patients, and primary ovarian insufficiency. I strive to create a positive, welcoming atmosphere in my exam room, so that each patient who comes to see me feels comfortable and that all of their needs are being met. Outside of my clinical practice, I advocate for my patients at the state and clinical level, teach future women’s health care practitioners at Yale, and conduct my own research on human reproduction. 

I’m overjoyed to be a part of the phenomenal team at Flo, and I hope that through this collaboration I can help even more people reach their goals of building a family through support and education.

Fun Facts

Outside of my work as an OB-GYN and REI specialist, I love to experience the outdoors by traveling, camping, hiking, and skiing with my family. I also enjoy painting watercolor and cooking without a recipe!
