There are many ways to collaborate with me. Whether you are seeking support for yourself through treatment or coaching, need supervision or mentoring to better serve your clients, or need consulting for your organization, you can book time with me here.

I knew David would pioneer the eating disorder world. I’ve had the privilege to be supervised by him. I am truly grateful for his profound insight and passion in this field.

Dr. David Wiss is one of the most influential registered dietitians in the field of behavioral health because he continually strives to challenge the status quo by asking hard questions, researching difficult nuances, and seeking common ground without compromising his personal and professional integrity.

Dr. David Wiss and his cutting-edge research are gifts to the evolving fields of eating disorder treatment and applied nutrition science by challenging ideological dogma, dismantling outdated rhetoric, and upgrading old-fashioned treatment models.

Private Practice

I sought supervision and mentorship from David nearly six years ago when I started working in a treatment center for substance use. Not only did I learn valuable clinical nutrition skills, but I learned much-needed counseling skills.

David's approach is as thoughtful and compassionate as it is knowledgeable. He's not afraid to challenge the status quo if it means getting the truth to the people who need it most.

David Wiss made himself available to me as a mentor on the topics of nutrition interventions for substance use disorder and eating disorders. I find myself referencing his work often.

Working With Dr. David Wiss

At my core, I am a clinician. Before even becoming a registered dietitian nutritionist twelve years ago, I have worked one-on-one with people and developed deep passionate for this transformative work. I’ve spent a large portion of my career conducting counseling with individuals struggling with disordered eating and related health challenges.

I’m a functional medicine practitioner recognized by the Institute of Functional Medicine (IFM), which means I’m trained to think in “systems” and investigate the root causes of illness. There are many tests that can help me discover more about you in the quest to find wellness.

I’m also a person with lived experience with recovery and available for coaching, mentoring, and other forms of personal or professional support. I stand on the shoulder of giants and am happy to walk shoulder-to-shoulder with you.

Finally, I am a mental health scientist. I’m trained to conduct original research, analyze data, and disseminate findings. I love presenting to my colleagues and welcome opportunities to speak with your organization.
