    About me – I am originally from Central Wisconsin and am currently living in Denver, Colorado. I am a PhD student at the University of Colorado Anschutz Medical Campus. When I am not in the lab, clinic, classes, or coaching, I enjoy exploring Colorado via mountain biking, kayaking, hiking, mountaineering, skiing, and overlanding. 


    Why did you start coaching? I started coaching because I have a passion for maximizing human performance and reducing the rates of obesity in the US. My overarching aim is to make a large-scale impact on the overweight and obesity rates in the US. I am working at a local level (coaching clients) and a global level (large-scale clinical interventional weight-loss trials) to achieve this goal. I hope to combine my training in nutrition and exercise (hence becoming a Registered Dietitian and MS in Exercise Physiology) to provide the highest quality information to my clients for maximal results!


    What is your coaching style? My coaching style is very supportive and empowering. I will be there for every client and treat each client as a unique individual to tailor their plan to their goals. I am very science-based and will provide clients with the most up-to-date research in the field. I cheer on my clients and help them through tough times, while always striving for consistency in the diet. I enjoy problem solving with clients if situations arise to help them overcome any obstacle. Intrinsic motivation is a powerful trait that I want to instill in my clients (but I am always there for some external motivation!)


    What kinds of clients do you work with? I enjoy working with any and all clients! From the untrained individual looking for some support on meal structure and general weight loss, to the hardcore strength/CrossFit athlete looking to improve performance. As a dietitian, I also enjoy working with people with medical conditions, such as T2DM, PCOS, hypothyroidism, etc.


    What is your favorite part of coaching? The best part about coaching is witnessing clients have success and seeing the “lightbulb moments.” Nutrition and weight loss can be overwhelming, but giving clients the tools to succeed is the most valuable thing I can do.


    What type of client would be the best fit to work with you? Recreational athletes who have performance and/or body composition goals. Untrained individuals looking for general weight loss and lifelong nutrition tips to maintain weight loss.
