Meet Kathy

Food has always been a source of joy, nourishment, and overall well-being in my life. I learned to cook at a very young age, and enjoyed creating dishes for my family and friends. Food was the center of every gathering, in a positive and nourishing way. Growing up with a backyard vegetable garden nurtured my understanding of the benefits that fresh, nutritious ingredients bring, as well as fostering the connection of food as medicine to nourish your body for optimal health. If you want to feel good, eat real whole food. Food plays a role in sustaining health and preventing disease. Today, as a mother and nutritionist, I am inspired to create healthy, delicious-tasting dishes to share with all of you. So you, too, could create a lifestyle that promotes wellness.


Kathy’s Health Philosophy

My health philosophy centers around lifestyle interventions to promote optimal wellness and combat chronic disease. My focus is rooted in following a whole-food, predominantly plant-based eating pattern that is satisfying and delicious. When you nourish yourself with plant-based, nutrient-dense foods, you’ll feel better now and live longer later.

Nourish Yourself With Delicious, Real Food.

It’s about what you add to your recipes, not what you take away. I show you how to create more nutrient-dense, whole food dishes that are nourishing, delicious, and mostly plants!

Nourish Yourself Through Movement.

Nourishing your body is more than the food you eat. I share how to nourish yourself with activities that promote movement, strength, and flexibility.

Nourish Yourself and Thrive Everyday!

Create a healthy body, mind, and nourishing life by eating intuitively, encouraging self development, and caring for your environment.  

Kathy’s Professional Organizations & Certifications

Kathy is a member of the American College of Lifestyle Medicine (ACLM). ACLM is the medical professional society providing quality education and certification to those practicing lifestyle medicine.

Lifestyle medicine is a medical specialty that uses therapeutic lifestyle interventions as a primary modality to treat chronic conditions including, but not limited to, cardiovascular diseases, type 2 diabetes, and obesity.  Lifestyle medicine clinicians apply evidence-based, whole-person, prescriptive lifestyle changes to treat, reverse, and prevent chronic disease. ACLM members promote lifestyle medicine as the first treatment option for chronic disease, as opposed to the first option of treating symptoms and consequences with expensive, ever-increasing quantities of pills and procedures. ACLM members are united in their desire to identify and eradicate the root cause of chronic disease.

The six pillars of lifestyle medicine are the following: a whole-food, plant-predominant eating pattern, physical activity, restorative sleep, stress management, avoidance of risky substances, and positive social connections.
