The most effective way back to a functioning brain and the beginning of the end of your eating disorder, is personalized nourishment and a solid strategy.

My mission is to help my clients learn to:

  • Stop obsessing over food

  • Start appreciating and trusting their bodies

  • Normalize their natural eating cues and discover what role food plays in their personally defined health.


I have specialized experience in the re-feeding of high medical risk cases, Binge Eating Disorder (BED), and I only work within a complete treatment team model. It is a policy of my practice that all clients must be working with a therapist with whom I may consult with in order to begin medical nutrition counseling sessions. This aligns with professional standards in the field and ensures each client is receiving the inter-professional expertise they need to fully heal from these multidimensional disorders. In order to make treatment more manageable I provide the option to work virtually with my clients in addition to in person appointments in Scottsdale.

Building trust and ensuring safety are key elements to my practice. I use humor and metaphor, helping clients to laugh, honor their achievements, and problem solve when we get stuck. Every client is unique and my combined expertise in both the psychological and nutritional aspects of these disorders gives me and edge in helping clients to overcome their illnesses. My direct, yet compassionate, support style will help you conquer even the most defiant eating disorder. Time to reclaim your power and rest assured... I’ve got your back!

I am a Certified Eating Disorder Registered Dietitian (CEDRD) and Medical Nutrition Therapist with extensive experience treating eating disorders exclusively since 1991. I have seen it all while fighting alongside my clients and against their eating disorders at every level of care. I can confidently say that those who make nutritional intervention, restructuring, and rehabilitation a priority in their recovery consistently have far greater and more sustainable outcomes. People suffering from eating disorders come in all shapes and sizes and present with a myriad of health complications all at varying levels of severity. Regardless of your body size, a starved and malnourished brain is a malfunctioning one!


Before you can get to work on the psychological components of what caused, and keeps you in your eating disorder behaviors, you have to provide your brain with the fuel it needs to do so. This has held true with my patients time and time again. I earned dual undergraduate BS degrees in counseling psychology and clinical nutrition at Arizona State University where I continued on to earn my graduate degree in clinical nutrition as well. I recently completed the requirements and am a Certified Eating Disorder Registered Dietitian as recognized by the International Academy of Eating Disorder Professionals.

I have had the opportunity to work in a number of different facilities in all levels of care while collaborating with wonderful doctors, dietitians, and mental health professionals. Some of these roles include:
