Now accepting new clients!

In-network with Anthem Blue Cross, Aetna, and United Healthcare.

At Renu Eating Disorder Treatment, we provide compassionate, evidence-based nutrition therapy to support individuals in their recovery journey. Our focus is on helping clients heal their relationships with food and body through individualized nutrition counseling, meal support, and a non-diet, weight-inclusive approach.

While our current focus is on nutrition therapy, our vision is to grow into a multidisciplinary practice that offers a full spectrum of eating disorder treatment services. We believe comprehensive care is essential for lasting recovery, which is why all clients are required to work with a therapist and maintain ongoing medical oversight. If you don’t already have these supports in place, we’re here to help connect you with trusted professionals in our network.

Meet Your Dietitian

Marisa Hernandez, RD

I’m Marisa Hernandez, a Registered Dietitian Nutritionist specializing in eating disorder recovery. I’ve worked across multiple levels of eating disorder care, including inpatient residential, intensive outpatient, and now private practice. My work is deeply shaped not just by my clinical experience, but by my own recovery journey—allowing me to bring empathy, understanding, and a non-judgmental approach to the clients I serve. I hold a Bachelor of Science in Nutrition & Dietetics from San Francisco State University and have been working with adolescents and adults in eating disorder treatment since 2021. I am currently pursuing certification as a Certified Eating Disorder Specialist (CEDS) to further deepen my expertise in this field.

I started Renu Eating Disorder Treatment with the vision of creating a supportive space where clients can explore healing at at pace that feels manageable for them. I believe recovery isn’t about achieving perfection—it’s about meeting each individual where they are, building trust, and gently working toward a more peaceful relationship with food and body. My approach is collaborative, compassionate, and rooted in evidence-based care, drawing from the principles of Health at Every Size (HAES) to support body acceptance and self-compassion.

I’m committed to walking alongside each client as part of their treatment team, offering guidance, encouragement, and hope as they navigate their healing journey.

Services:

Our practice provides individualized nutrition therapy to support clients struggling with eating disorders, disordered eating, and body image concerns. Our services include:

  • One-on-one nutrition counseling for eating disorder recovery

  • Meal planning and meal support

  • Intuitive eating and weight-inclusive care

  • Collaboration with your treatment team for coordinated care

Since eating disorder recovery requires multidisciplinary care, we require all clients to have a therapist and medical provider as part of their support system. If you need assistance finding these providers, we can help connect you with trusted therapists and medical professionals who specialize in eating disorders.

As we grow, our goal is to build a multidisciplinary team to provide even more comprehensive care under one roof.
