Richmond’s Premiere Health and Weight Management Center, specializing in a customized approach to permanent, healthy, lifestyle change.



Zacharias Ganey Health Institute (ZG) specializes in weight management and lifestyle change, by providing health related education, progressive physical activity, and a myriad of supports.

The ZG KEY (Knowledge, Energy and You) Healthy Lifestyle Change Program was designed to help ZG members lead a healthier, more active life, including helping members boost metabolism, lose weight, reduce medications, improve body composition, and take ownership of their health. The main purpose of the ZG KEY Program is to not only help members achieve optimal personal success by giving them the necessary tools and support, but also to assist in removing obstacles to healthy habits.

Since 2002, over 12,000 people from all walks of life and from over a hundred mile radius come to ZG for the ZG KEY Program. After the first ten weeks of the more intensive phase, most continue on as program members in order to make their new health habits permanent.

Some members with specific health conditions such as chronic pain, orthopedic disorders, arthritis, and fibromyalgia travel from afar to enjoy the large, heated shallow pool at our Ginter Park location.

ZG has two locations, one in the Ginter Park area on the Northside of Richmond and one in Chesterfield on the Southside of Richmond. At ZG we are proud to serve the health and wellness needs of Richmond and the surrounding community.

Our Mission


Zacharias Ganey Health Institute’s mission is to empower individuals to take control of their health and improve their quality of life through medical and nutrition education, individual counseling, group support, supervised group strength and cardio training, and continuous follow-up and accountability.
