What we do

Detoxes and diets are dead-ends when it comes to making real changes in your wellness. At Culina Health, we know that getting healthy is a multifaceted and oftentimes difficult journey. That's why we provide trustworthy support and resources to help you understand and overcome the physical, mental, environmental, and behavioral challenges that get in the way of being healthy. 

Tired of feeling powerless, confused, and frustrated about your health?
Eating should be easy, right? 

we're here with a smarter approach to reaching your health goals

Our personalized nutrition coaching and science-based online education helps take the stress away from eating so you can transform your health and live a balanced life. 

Our goal is to help you understand your body, change your relationship with food, and build healthy habits so you can get results that actually last.

We respect the role of family, community, and culture in shaping health behaviors, and celebrate the diversity of the human condition and experience regardless of race, socioeconomic status, gender, sexual preference, body size, or health condition. 


We honor the fact that you know your body better than anyone else. That's why we work WITH you to find a plan that works for your unique needs.  We support you along the way by respecting you and your decisions, and providing non-judgmental and mutually collaborative care that emphasizes communication, empathy, and positivity.


As Registered Dietitian Nutritionists our care plans are rooted in our professional training and continued education in nutrition, health and behavioral science. Our coaching methods and education are always informed by science, research, and clinical experience.  


We help our clients feel empowered in all facets of their life. We provide the tools and support so that you can take an active role in your health and keep doing the work when we're not around.


We strongly believe that food is medicine, and that what we eat can have a powerful impact on so many aspects of life - physical health, mental and emotional health, stress management, work performance and relationships. That's why all of our work is centered around these core values:
