Q & A

Q: Where did your interest in reproductive endocrinology come from?


As a young girl I was taught many baseless things about contraception and reproduction, so to better educate myself, I pursued the study of developmental biology as an undergraduate where I was introduced to hormone function and embryonic development. During my medical training, reproductive endocrinology became a natural path to follow based on my interest in reproductive health. As I cared for more infertility patients, I became passionate about finding and researching solutions to help patients have a healthy baby. I am thankful my path led me to become a reproductive endocrinologist because I am not sure there is a more rewarding job than helping people build their families.

Q: What is your approach to helping patients who are struggling?


Listening to my patients and their experience is the single most important thing I can do to understand why someone is struggling. It is important to me that my patients feel heard. This provides a basis for trust, mutual respect, and shared decision making so, together, we can effectively help them achieve their reproductive goals.

Q: Describe a time you were inspired by a patient.


I am always inspired by my patients. Their willingness to be emotionally vulnerable about their most personal experiences in my office is inspiring. I see strong people every day in my office who are walking a long, difficult path and display such tenacity and courage; I am inspired daily to go above and beyond to help my patients achieve their reproductive goals.

Q: What about SGF makes you the proudest?


SGF is known as a pioneer in many ways, shown through their commitment to research, innovation, collaboration, and education. I’m proud to be a part of a practice of this caliber, home to award-winning physicians who continuously and safely push the envelope and offer the very finest in care.

Q: Who inspires you?


My mom is my biggest inspiration. She immigrated to the U.S. from Guatemala after high school. Despite her interest in science, where she was raised prevented her from pursuing medicine as a female. My mom eventually became a nutritionist and dietician and raised me to understand that how we nourish our bodies is a form of medicine, too. She always fostered my love of science and has remained a constant inspiration to never take my opportunities for granted.

Q: What do you enjoy doing in your spare time?


I love spending time with my husband and our three children. We are avid skiers and go to the mountains often. We enjoy seeing extended family whenever we can. I also enjoy being active outdoors, dinner parties with friends, and playing music.

Q: How would you describe your personality?


I am charismatic, compassionate, and inquisitive. I tend to see the glass as “half full” but am also pragmatic.

Q: What is something about you that would surprise most people?


I raced in triathlon collegiate national championships as an undergraduate.
