Clinical nutrition with heart

"Food is fuel; it can also be a source of comfort, of stress, and one of our longest lasting relationships. I believe we can eat in a way that supports health, helps us feel our best, and still leaves room for joy.”

— Michelle Shamailov, RD, LD, CCTD

Our Philosophy

Longevita care is evidence-based and rooted in medicine, and also appreciates a whole-person holistic approach incorporating mind, body, and lifestyle into your care. When one of these parts is broken, the whole system struggles.

We will educate and implement clinical guidelines; we will help provide structure and results-driven interventions. We also understand that eating behavior is shaped by more than knowledge. Many factors play a role in our habits and what actually works. Flexibility and balance matter. Your quality of life matters.

For effective nutrition counseling, we’ll account for all of it.
