Steadier blood sugar, with food you actually like.

VisitsIn person and telehealth

Care built around your kind of diabetes.

Every type of diabetes asks different things of you. Your plan starts with your labs, medications, devices and daily routine, and builds from there.

Type 2 and prediabetes

Bring your A1c down with meals built around your schedule, culture and cravings.

Whole grains and complex carbs: brown rice, soba noodles, jicama and dal

Type 1 and insulin-dependent diabetes

Today's pumps forgive imperfect carb counts. We focus on what still matters: knowing how your meals, from rice to pizza night, move your glucose.

GLP-1 medications

On Ozempic, Wegovy, Mounjaro or Zepbound? Enough protein and nutrients while your appetite is low, fewer side effects, and keeping the muscle you've built.

Proactive care starts at the table.

Nutrition is one of the most powerful tools you have for managing diabetes. I help with the daily details that move your numbers: breakfasts that don't spike you by 10am, afternoons without the crash, and dinners out without a night of alarms.

Your medication does its best work alongside foods that work for you.

What we can dig into

For people with type 1, type 2, or prediabetes who are tired of chasing their numbers and want a plan that fits how they really eat.
