Your clinic’s nutrition partner

Longevita provides evidence-based, individualized nutrition care for cardiovascular disease, surgical optimization, cardiometabolic health, and resilient aging.

Led by Michelle Shamailov, RD, LD, CCTD — with fifteen years of clinical experience including nine years as the advanced heart failure, LVAD, and transplant dietitian at Ascension Seton's Heart Specialty Care and Transplant Center — Longevita brings hospital-level clinical nutrition expertise into private practice.

The 'Partners' in our name is intentional.

We operate with empathy and integrity for care that you and your patients can trust.

How to refer patients

Telehealth services available across Texas & beyond. In-home services offered within Travis & Williamson counties.

Direct patient referral

Share our contact information or flyer with your patient. They book directly online at longevitanutrition.com at their convenience.

Coordinated referral

Your office can send a referral note via HIPAA-compliant fax or secure e-mail. Upon request, we will follow up with our assessment and clinical summaries of our visits — provided the patient has consented to record sharing.

In-office and partnership services

For clinics seeking a more integrated arrangement, Michelle offers a limited number of recurring in-person, on-site partnerships in the greater Austin area. Cases are discussed in real time with a written assessment provided to your team after each visit, with patient consent. 

Starting September 2026. 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 recommendations 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

Feel confident in the nutrition advice and materials your team is sharing with patients daily.

A note on in-office partnerships:

In-office services are available to a limited number of clinic partners, depending on location and scheduling. All patient services are billed directly to patients through Longevita LLC. Alternative billing arrangements, including clinic-bundled services, can be discussed on inquiry.

Longevita operates as an independent contractor. Patient consent for record sharing is obtained prior to any clinical communication with your practice.

Designed for meaningful results

Longevita nutrition counseling can help:

  • Improve dietary compliance and guide behavior change

  • Reduce complications and hospital readmissions

  • Improve surgical outcomes and recovery

  • Aid wound healing, reduce infection risk

Nutrition is consistently undertreated in cardiometabolic and surgical populations — not because clinicians don't recognize its value, but because accessible, qualified outpatient nutrition care is genuinely hard to find. Longevita fills that gap with a level of specialization and communication most practices cannot offer.
