Dr. David Wiss, PhD, MS, RDN, is a true standout in the mental health and nutrition field, a rare find after years of searching for the right provider. I first worked with him in 2015 when I was teetering on the edge of relapse and entering IOP. His genuine, down-to-earth approach instantly put me at ease, creating a safe space to explore the mind-gut-body connection and address the chronic lack of bowel movements I have struggled with for what feels like a lifetime. Dr. Wiss’s passion for his work is evident in his groundbreaking research and unwavering dedication to his clients’ well-being. His ability to connect authentically while offering expert guidance had a profound impact on my life. He’s truly extraordinary, and I wholeheartedly recommend him to anyone seeking life-changing, authentic support in recovery.

Dr. David Wiss brings a very balanced, caring, multi-faceted and fact-based approach to helping me understand what is going on behind any residual desires, confusions, feeling of lack, body misperceptions etc. where body, health and nutrition is concerned. He's one of the smartest writers out there on these subjects. Dr. David has helped me find even more balance in the way I approach my nutrition as an aging woman along with helping me have a more compassionate approach to an aging body. He is able to point to truths that I couldn't see or seem to miss and does so in a jovial and caring way. He fully understands how addiction may have affected our outlook and is able to gently bring one back into the right lane for maximum movement forward. I recommend Dr. David for anyone who wants to go further with their nutritional health and mental wellbeing.

He has a rare gift for taking complex nutritional and mental health concepts and distilling them into clear, elegant, and practical guidance. I couldn’t imagine anyone else I’d rather have in my corner when it comes to improving my health, understanding nutrition, and becoming the best version of myself. And if you’re lucky enough to hear his personal story, you’ll walk away even more inspired — and even more certain you made the right choice in seeking him out.
