Kerry Graff, MD


Dr. Graff graduated from Cornell University Summa Cum Laude as a Biology major in 1990.  After graduating from the University of Pittsburgh School of Medicine Cum Laude in 1994, she completed a three-year Family Practice Residency at UPMC Shadyside in Pittsburgh, PA.

Dr. Graff relocated to Canandaigua, NY in 1997 following completion of her residency. She was employed by Thompson Health, providing primary care including obstetrics at the Honeoye Family Practice, for nine years before deciding to open her own practice in Canandaigua in 2006.

After learning about the impressive health benefits of a whole food plant-based, she personally adopted this way of eating and has been teaching it to her patients ever since. She has partnered with J. Morris Hicks, the creator of the 4Leaf program and author of Healthy Eating, Healthy World to further develop tools for educating patients. You can learn more about her personal journey here.

Dr. Graff is a member of the American College of Lifestyle Medicine and holds a Certificate in Plant-Based Nutrition from the T. Colin Campbell Center for Nutrition Studies and eCornell. She remains board certified in Family Medicine and a member of the American Academy of Family Practice. In addition to caring for patients and running her primary care office, she is the Chief Medical Officer of 4Leaf Global.

She has two children—David, age 18, adopted from Vietnam, and Erica, age 15, adopted from South Korea. Dr. Graff organizes and swims in the annual Canandaigua Lake Swim to benefit hospice care. This one mile swim across the width of Canandaigua Lake was started in 2000 in memory of her dear friend and mentor, Dr. David Reed.  To date it has raised over $160,000.

She also holds a Certificate in Plant-Based Nutrition, which she earned through eCornell and the T. Colin Campbell Center for Nutrition Studies.

After watching Forks Over Knives and doing extensive research, Kristin began steadily transitioning from a vegetarian to a whole food, plant-based diet. Since then, her heath has improved dramatically and she feels better than ever.

In her spare time, Kristin enjoys learning everything she can about health and nutrition. She also likes running, biking, swimming, hiking, and spending time with her husband and pets.
