“I worked with Collin over about 8 month time span in 2024. Initially he provided a daily nutrition plan that was tailored around the type and time of each days exercise or rest. We had weekly accountability calls to keep me on track. The calls also included some relevant nutritional topics that were very beneficial.
I worked with him while trying to lose weight for a specific event. Since that time, I have continued following his plan and have continued to stay on track.”

“Dr. Popp has been a fantastic resource for me as my health, fitness, and athletic goals have changed over time. His system is intuitive and made tracking macros a lot more manageable than others I've tried in the past. Plus, his approach is realistic. I never felt like I had to maintain unrealistic diet standards, which helped me integrate his tools in a more sustainable manner. Thank you, Dr. Popp!”

Working with Collin was extremely helpful on many levels. Our one-on-one sessions educated me on the path we were taking and provided weekly conversations and reviews that both acknowledged my progress and allowed us to quickly make adjustments when necessary.
Collin ensured I felt comfortble with our process and gave me complete personal access when questions came up.
I exceeded my goals through smart steps and oversight. And, what I personally enjoyed was his approach; delivering and reviewing education materials on a range of relevant topics including body dynamics, nutrition and physical activity. This helped drive my weight loss process!

Working with Collin was a pleasure. They helped me achieve every goal I had going into this. Collin and his team care, and their actions only further affirm this. The team provides true 1v1 insights, not an off the shelf template. They are available for questions during the ramp up phase and then when you feel like you have your feet under you they help you take the training wheels off so you can excel.

I recently had the pleasure of working with Collin, and I can’t say enough good things about my experience. From the very first consultation, he took the time to really understand my goals, challenges, and lifestyle. His approach was personalized and realistic, making it much easier for me to stick to the plan.
What really stood out was how supportive and encouraging Collin was throughout the process. He provided me with practical advice, meal ideas, and helpful resources that fit seamlessly into my daily routine. I’ve not only achieved my goals but also learned sustainable habits that will benefit me for the long term.
If you’re looking for a knowledgeable, compassionate, and effective dietitian, I wholeheartedly recommend Collin. He genuinely cares about his clients and is committed to helping you succeed. Thank you, Collin, for making such a positive impact on my health journey!

Collin provided weekly nutrition coaching over a four month period. I experienced great results that exceeded my expectations. Collin was knowledgeable, reliable, accessible, and easy to work with. His coaching was actionable and minimized the decision making on my part. I would highly recommend working with Collin!

Collin was a thorough and attentive nutritionist that changed my eating habits for the long term. He is able to easily convey nutrition and lifestyle facts in a way that is digestible, and therefore easy to turn into habits. He created an effective eating plan for me and my partner, and worked with us a couple and how we can incorporate a healthy lifestyle during our weekly grocery runs and also during our nights eating out. Collin was always an email or text away and would answer even the most specific questions we each had about things that were challenging in our daily lives. He always had solutions and really helped us change the way we think about food forever. 10/10 recommend!

Collin is without doubt the best nutritionist I have worked with. He is very knowledgeable but makes the process simple, attainable, and maintainable. I've worked with a few nutritionists and Collin is the first one I'd work with again. I cannot recommend him enough.

I set out with a goal to improve my diet, lose a little bit of weight and get a bit more toned. Collin was really great - developing a custom plan based off my schedule, dietary preferences, etc. He broke the process down clearly, answered all questions and was always available to answer questions.
I reached my goals and was able to maintain after the program ended.
Highly recommended.

I cannot rave about Dr. Popp enough. From our first session he listened to me and walked me through everything step by step. He is so patient. No question felt ridiculous. He was so encouraging and supportive. He kept me accountable through the whole process. I would 1000% recommend him to anyone looking to work with a nutritionist--especially if you are an athlete. As a mom of 3 and in my 40s, losing weight isn't easy by any means. But Dr. Popp helped me to feel good in my body again.
