Leandro's medical interests encompass geriatrics, palliative care, and public health, reflecting his commitment to comprehensive patient care and community well-being. His passion for palliative care was profoundly influenced by his grandfather’s situation, an experience that shaped him as a physician and deepened his resolve to provide compassionate care for patients and their families.

Vanessa Boosahda, MD

Medical Education: Xavier University School of Medicine
Undergraduate Education: University of Mary Washington

Born and raised in Northern Virginia, Dr. Boosahda has been on a winding (but rewarding!) path to Family Medicine. She completed her undergraduate studies at the University of Mary Washington and earned her medical degree from Xavier University School of Medicine.

Along the way, she discovered a passion for mentorship, especially helping students prepare for the USMLE and residency. After navigating her own set of hurdles, she realized how powerful it is to hear “you’re not alone” and has been paying that message forward ever since to the students she tutors and supports each and every week.

She fell for Family Medicine after going through each rotation in medical school and thinking, “this might be the one!” But it was at the AAFP conference where everything truly clicked. Hearing the stories of attendings and residents who were passionate about full-scope patient care, meaningful relationships, and making a difference in their communities, she saw herself in those stories and knew she’d found her people.

Dr. Boosahda chose Saint Francis because she finally felt the “click” everyone talks about when you know you’ve found your match. From the moment she met the faculty and residents, she knew this was the place where she belonged.

Clinically, she’s interested in full-scope Family Medicine, with a special love for women’s health, obstetrics, mental health, and procedures. Outside the hospital, she keeps her hands just as busy with decorating intricate pysanky, turning wood into one-of-a-kind art, trying to convince her cat Southpaw to cuddle with her, and spending as much time as possible with her family and the ones she loves. Her nieces and nephew are her greatest motivation because they remind her of what matters most and who she’s working so hard for (besides Southpaw).

To further his professional career, Luis relocated to New York and began working at Jamaica Hospital.

Inspired by the dynamic and fast-paced environment, he decided to pursue medical school at St. George’s University in Grenada. During his clinical rotations, he found great fulfillment in the variety of cases and the opportunity to provide comprehensive care to patients, which ultimately led him to choose family medicine as his specialty.
