Our Team

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 a private medical 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 partnered with J. Morris Hicks, the creator of the 4Leaf program, to write the 4Leaf Guide to Vibrant Health in 2015 and 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 was among the first cohort to become board certified in Lifestyle Medicine in 2018. She 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 her patients, she serves as 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 helps organize and swims in the annual Canandaigua Lake Swim that now benefits Light Hill Comfort Care Home in Canandaigua.   The Canandaigua Lake Swim was started in 2000 in memory of her dear friend and mentor, Dr. David Reed.   To date it has raised over $200,000 for hospice.

When not in the office, she is likely to be found at the farmer’s market or in the produce department at Wegmans, walking around Canandaigua with her ridiculously adorable dog, Bailey, at yoga, or on a cross-country ski path.

Katie McMillen, PA-C

Katie grew up in the Finger Lakes region and graduated magna cum laude from the Rochester Institute of Technology Physician Assistant program in 2017. Since then, she has worked as a Family Medicine PA in Canandaigua, NY. She is a member of the American Academy of Physician Assistants and Rochester Regional Physician Assistant Association.

Her special interests include women’s health and community outreach. Katie’s goal is to improve public health through a practice based in Lifestyle Medicine and Preventative Health.

In her free time, Katie enjoys reading, experimenting with new whole food plant-based recipes, and many outdoor activities including skiing, rock climbing, paddle boarding, and walking local trails with her rescue dog, Apollo.

Rebecca Kelly, RN and Health & Wellness Coach

Rebecca graduated from the Ohio Valley School of Nursing in Pittsburgh, PA in 1993 and has since worked in Family Practice, Pediatrics, Labor & Delivery, and College Health. Although Rebecca is new to this practice, she and Dr. Graff worked together at the Family Practice Residency at UPMC Shadyside from 1994 to 1997.

Since choosing a plant-based lifestyle in 2015, Rebecca has delved deeper into the health benefits of plant-based nutrition and Lifestyle Medicine.

After reading numerous books such as “The China Study”, “Whole”, and “How Not to Die”, she received a certificate from Wellness Forum Health for the Diet and Lifestyle Intervention Course.

In 2018, Rebecca enriched her years of nursing with training as a Health & Wellness Coach through Wellcoaches School of Coaching. The opportunity to help people rediscover their best selves through Lifestyle Medicine and Individual Coaching is a unique opportunity for her as a nurse, and she is very excited to be doing this work with Dr. Graff and Kristin at Rochester Regional Health!

Rebecca lives in Canandaigua with her husband, three big kids, and many pets. She has a passion for animal rescue and fostering and spends many weekends transporting dogs and cats to new and better lives! She loves yoga and cycling, but can usually be found (or lost!) on the many wooded trails all over our beautiful Finger Lakes region.

Kristin Keyes, Practice Coordinator

Kristin joined Dr. Graff at Lake Country Family Medicine in 2014 and transitioned to RRH Family & Lifestyle Medicine in 2018. She graduated summa cum laude from the University of Pittsburgh with a Bachelor’s Degree in Psychology and a Leadership Certificate. She also earned a Certificate in Plant-Based Nutrition through eCornell and the T. Colin Campbell Center for Nutrition Studies in 2014. She is currently enrolled in a year-long permaculture course to learn more about how to sustainably grow food by working in harmony with nature.

After watching Forks Over Knives and doing extensive research, Kristin transitioned to a whole food plant-based diet. Since then, her heath has improved dramatically and she has become a passionate advocate for a WFPB diet for our health, the environment, and the amazing animals we share our planet with.

In her spare time, Kristin can usually be found with her husband and rescued pets, experimenting in the kitchen, or working in her yard that she hopes to turn into a gigantic garden. Some of her favorite adventures include spending time at the ocean, exploring the Ontario County Pathways, visiting local animal sanctuaries, and practicing yoga (almost) daily.
