Hello, I’m Michelle! I was born and raised in Michigan and have happily called Texas home since 2014. Outside of “dietitian life” and building my small business, I enjoy spending time with my two young children, making art & crafts, being in nature, and creating tasty, low effort meals from simple ingredients.

My Experience
Prior to founding Longevita, I was honored to spend the last decade as the primary dietitian for the Heart Specialty Care and Transplant Center at Ascension Seton Medical Center Austin, specializing in advanced heart failure, LVAD, and heart transplantation. In this role, I worked concurrently in both the inpatient and outpatient settings to provide the full continuity of care.
I’ve experienced the full spectrum of cardiac disease:
from counseling busy executives during their lunch break
to supporting critically ill patients in the ICU on life support.
Previous positions in rehabilitation and long-term care deepened my understanding of how nutrition and lifestyle shape resilience and long-term health outcomes.
These experiences — evaluating transplant candidacy, developing nutrition protocols, and guiding patients through heart failure, diabetes, malnutrition, surgical recovery, and major lifestyle change — now inform every client interaction.
I never wanted to be the person who handed patients a list of restrictions and sent them home. I wanted to be the one who helped them figure out how to keep eating what they love, while taking care of themselves at the same time.
My Mission
I’ve watched individuals’ health trajectories unfold over a span of many years, and have seen firsthand how habits can influence whether someone returns to a full, independent life after a major health event, or faces ongoing challenges and repeated hospitalizations.
I’ve also seen what happens when nutrition is addressed too late — or not at all.
My goal for Longevita is to extend specialist nutrition care outside of medical centers to reach others who would benefit — earlier in their health journey, more continuously, and in a way that fits daily life.
