  • Megan Cavanaugh, MD

    Born and raised on Long Island, New York, Megan went on to receive her Bachelor of Science in Biology from Northeastern University in Boston. At Northeastern, she developed her interest in medicine while simultaneously discovering a passion for working with underserved communities through volunteering at local hospitals and working on the planning board of the University’s Relay For Life fundraiser. Megan stayed in Boston to work in cancer research,contributing to several immunotherapy clinical trials at Dana-Farber Cancer Institute.

    After many Red Sox games and runs along the Charles River, Megan finally made her way back to New York to become the first physician in her family, attending New York Medical College. As a medical student working in New York City’s public health care system, she learned more about the socioeconomic and racial disparities patients face and became involved in research efforts to educate fellow medical students on ways to mitigate their implicit biases. In addition, Megan advocated for patients during her time on the Public Health Commission with the New York State Academy of Family Physicians, where she also gained insight into how physicians can fight for their patients through proposing legislation and lobbying government officials. She believes in a doctor’s responsibility not only to their patient but the community as a whole, one of the many reasons she pursued family medicine!

    Megan is excited to continue her journey at NYP-Columbia Family Medicine, where she hopes to give patients and their families the comprehensive healthcare they deserve. She is thrilled to pursue her interests in reproductive health, advocacy, and preventative medicine, among many others. Outside of medicine, Megan enjoys time consuming baking projects, running all over the city, and spending time with her family and friends.

  • Ella Chaffin, DO

    Ella was born in Maine and raised in a small town in the mountains of Colorado. She attended Colorado State University and majored in Human Development & Family Studies. As a University Honors Scholar she completed her Senior Honors Thesis on a research project exploring type 2 diabetes mellitus risk factors in adolescent girls with depressive symptoms. This experience helped form her interests in primary care, mental health, and disease prevention. Following graduation Ella moved to Madrid, and later Barcelona, to work as an English language teacher, primarily with elementary school children. During this time, she took advantage of the opportunity to improve her Spanish language skills to better serve her future patients. She fell in love with the Spanish language, culture, food, atmosphere, and lifestyle, and met her husband, Pablo.


    Ella attended the Chicago College of Osteopathic Medicine at Midwestern University. While in medical school she became involved with the Community Health Clinic, a volunteer-based health center providing free primary care and mental health services to uninsured patients in the Chicago area. This furthered her passion for community medicine and working with underserved populations in an urban setting.


    She is thrilled to be joining an incredible team of physicians at the NYP-Columbia Family Medicine Program. Her interests include reproductive health, addiction medicine and preventative care. Outside of medicine, Ella can be found baking sourdough bread (a pre-pandemic hobby if you can believe it), exploring the various neighborhoods in Manhattan, and taking weekend escapes to the mountains that remind her of her hometown in the Rockies. 

  • James Camacho, DO

    James was born and raised on the island of Saipan, the capital of the U.S. Territory recognized as the Commonwealth of the Northern Mariana Islands (CNMI). It was in high school where his journey to medicine began, providing music therapy to his grandmother in hospice before her eventual passing during his senior year. After graduating from high school, James moved away from home to pursue his dream of becoming a physician to one day return to serve his own island community in the CNMI. 

    James went on to pursue a Bachelor of Arts degree in Biology from the University of Hawai’i at Manoa. While completing his prerequisite courses for medical school there, James learned so much about the importance of his cultural identity as an indigenous person, modeled very passionately by the Native Hawaiian community. This deeper understanding of his culture became reflected in his work as a resident assistant, upholding student safety as taught by native Hawaiian and his own Samoan and Chamorro cultural values, respectively. This type of service work helped him garner an internship at the Office of Insular Affairs under the Department of the Interior in Washington, D.C., where he learned about strategies to improve the operational capacity of indigenous communities and how they can move forward to a state of self-determination with guidance from the federal government. Following his graduation from the University of Hawaii in 2016, James relocated to Portland, Oregon to obtain more healthcare experience as a medical scribe and hospice volunteer before applying to medical school.   

    James attended Western University of Health Sciences College of Osteopathic Medicine of the Pacific Northwest (WesternU COMP-NW) in 2019. He served as the president of the Equality Alliance Club and even founded the school’s Cultural Awareness Club. He was COMP-NW’s very first Diversity Officer under Student Government and even helped organize in-person and virtual leadership seminars for physicians during the Covid-19 pandemic for several counties in the State of Oregon. He was also a member of the Gold Humanism Honor Society, recognized for their attention to compassion and humanism in clinical practice. His medical passions include diabetes medicine, palliative care medicine, improving the health literacy in indigenous communities, and advocating for an increased capacity of healthcare services to remote island communities around the world. 

    James is so excited to be a part of the NYP-Columbia Family Medicine Residency program and looks forward to serving the community of Washington Heights by learning more about the people through their language and culture. In his spare time, James enjoys reading, exploring the city via public transportation, playing racquet sports and volleyball, celebrating The Arts, going thrift shopping, grabbing boba tea, and reflecting in his journal.

  • Robert Volodarsky, MD

    Robby and his fraternal twin were born on the Upper East Side at The New York Hospital which merged with Presbyterian Hospital a couple years later to form NewYork-Presbyterian. During high school he played home football games on 193rd and Audubon Ave, about halfway between Columbia University Irving Medical Center and The Allen Hospital. As an undergraduate he attended SUNY Binghamton in upstate New York where he studied Biochemistry and served two terms as Service Chair of his medical organization. After graduating he completed one year of biochemistry research studying cellular trafficking proteins which play a role in disease states such as Spinal Muscular Dystrophy when mutated. He attended Drexel University College of Medicine in Philadelphia for medical school where he was twice elected Service Representative of his learning society. During pre-clinical years he enjoyed volunteering at health fairs and free clinics that provided underserved residents of Philadelphia with medical care. His third year was completed at Crozer-Chester Medical Center in impoverished Chester, PA. It is there that he discovered his love for Family Medicine as he witnessed the breadth of care that doctors in that specialty were able to provide their patients. He particularly enjoyed conducting home visits and working at the Federally Qualified Health Center that served underinsured patients including several undocumented families spanning generations. Many of these patients were seeking medical care for the first time in the United States and had severely untreated conditions. Through it all Robby was blown away by the compassion and dedication to holistic care that the Family Medicine doctors embodied and decided that was the kind of physician he wanted to be. Prior to graduating he was awarded the Daniel M. Tabas Award for outstanding scholarly achievement within the pursuit of Primary Care.

    Robby is elated to return home to NYC and train within the prestigious NYP-Columbia system while serving his community. In his down time he enjoys watching professional football and basketball or anime, going to the gym, playing videogames, and hanging out with his childhood friends – many of whom still reside in the city.
