Hello! I was born and raised in Michigan and have been happy to call Texas home since 2014. In my personal time, I enjoy playing with my two young children, laughing with my husband, exploring nature, messing with watercolor paints, and figuring out how to piece together simple ingredients into exciting meals.
My Experience
I spent over 10 years at Ascension Seton Medical Center Austin, including nine years as the primary dietitian for their Heart Specialty Care and Transplant Center (2017-2026), 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 worked across the full spectrum of cardiac disease:
from supporting critically ill patients in the ICU on life support
to counseling busy executives on their lunch break.
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.
I founded Longevita to extend the level of nutrition care that exists inside hospital specialty programs to others who need it — earlier in their health journey, more continuously, and in a way that fits daily life.
