About Justin

I'm a California-based, registered dietitian with several years of experience working in both inpatient (hospital) and outpatient settings. My passion for nutrition originated from my own journey managing a chronic health condition, Crohn's disease, which proved a significant challenge during my teenage years. Becoming knowledgeable and intentional about nutrition changed my life and led to a desire to help others to do the same.

Approach to care

Nutrition sessions with me will focus on developing a personalized nutrition plan that balances your nutrient needs and health goals with your food preferences and lifestyle. I translate the latest nutrition and exercise research into practical advice and resources that you can apply in meaningful ways. Clients will receive meal planning guides, grocery lists, meal & snack ideas/recipes, and exercise plans.

Your first session with Justin

During your first session, expect some basic questions to get to know you, your health, and goals. Then, we will get to work on developing your personalized nutrition plan to meet your health goals. I encourage you to come prepared with questions and interrupt me anytime a new one pops into your head. The more questions you ask, the more confident you will feel when you leave the session and start to apply my recommendations.
