Lifestyle Medicine

A primary care membership program treating the whole person

The lifestyle medicine institute is now a wellness membership program. Patients can closely partner with their provider on their healthcare journey through more in-depth visits, advanced screenings, access to specialists and custom plans that are developed to reach your personal health goals.

This one-to-one, personalized care requires membership into the program.

The wellness membership program provides many associated benefits, which include:

  • Visits in the same convenient medical office with minimal wait time
  • Same-day or next-day appointment availability
  • Direct access to provider team via email
  • Longer, more in-depth visits that include lifestyle/health assessment, full lab review and customized wellness plans
  • Additional health resources, such as sleep pattern review, and access to a new body composition machine to help with weight loss and fitness goals
  • Personalized lifestyle education
  • Access to physician/patient library and reading recommendations for specific health concerns
  • Expedited access to specialists, as needed
  • Accessible healthcare to lower-income families
  • Dependents (18-24 years old) out-of-town family and friends can be seen as non-members for acute medical problems
