Additional Information

The Choctaw Nation Diabetes Prevention Program (DPP) is a year-long program. The program is group based with up to 12 people in a group and one lifestyle coach to guide and support participants throughout the program. The lifestyle change program is conducted via WebEx, a virtual meeting platform allowing more flexibility for participants with in person cohorts coming soon in various locations. In this program, participants will learn how to eat healthier in a realistic manner that fits individual needs, how to increase physical activity level and how to manage the stress of everyday life. Participants will set goals, and with the help of a lifestyle coach and group support, reach individual goals and be able to maintain them for a lifetime.

Sessions will be held once a week for 16 weeks, then twice a month for two months, and finally once a month for six months until the year is completed. This program is not intended for those who already have diabetes. If you do have a diagnosis of diabetes and want help making lifestyle changes, contact your local clinic and speak with the Diabetes Educator.

Instructor: Lee Ann Sherrill
I have been a lifestyle coach for the National Diabetes Prevention Program since 2012 and a Master Trainer since 2018. I started my career with Choctaw Nation in 2001 as Diabetes Educator and became a Certified Diabetes Educator in 2004. I believe small lifestyle changes can delay or prevent diabetes, keeping Choctaw Nation families and community members strong and healthy.

Instructor: Jay Tisho
I have been a lifestyle coach for the Diabetes Prevention Program since 2018, and I’ve enjoyed working with community members as a health coach for the Choctaw Nation since 2005. Diabetes is a condition that is all around us in Oklahoma, and the first line of defense is prevention. I want to help you prevent diabetes and become the healthiest version of yourself. Together we will work on making healthy changes to your diet, activity level, and stress management that you will be able to sustain for a lifetime.
