In-office partnership services

For clinics seeking a more integrated arrangement, Michelle offers a limited number of recurring on-site partnerships. Patients are seen in person in your office, with cases discussed in real time and a written assessment provided to your team after each visit. 

Starting October 2026 in the greater Austin area. To inquire, please use our contact form or email michelle@longevitanutrition.com

Pre-op nutritional risk and frailty assessments

Using validated assessment tools, Michelle will stratify your surgical patient's nutritional and frailty risk, providing either clearance or suggested target goals and an individualized prehabilitation plan.

Nutrition consultations

Individual nutrition assessments, education, and care plans conducted in your office alongside your clinical visit.

Group classes

Single sessions or series, on-site or virtually. Content is tailored to your patient population and co-branded with your clinic. 

Professional consulting and staff education

Nutrition is addressed in medical offices daily — feel confident in the advice and materials that your team is sharing. Examples include lunch & learns or creation of custom educational handouts.

A note on in-office partnerships:

Longevita operates as an independent contractor. Patients must sign Longevita’s consent to record sharing prior to any case-specific discussion or notes. All patient services are billed directly to patients through Longevita LLC. Alternative billing arrangements, including clinic-bundled services (example: including a dietitian visit at your clinic as part of a surgical package), can be discussed on inquiry.

Designed for meaningful results

  • Improve dietary compliance and guide behavior change

  • Reduce complications and hospital readmissions

  • Improve surgical outcomes and recovery

  • Aid wound healing and reduce infection risk
