Hallo! And welcome to Transition Nutrition.

We specialize in healing relationship with food, movement, and body - and helping you figure out what that even means in the first place.

This includes making life after sport suck less and mean more by supporting former athletes navigate the transition from competitive athlete to "normal" human bean.

Athletes face unique challenges when it comes to food, movement, and body image pressures. We understand how intricately - and messily - they all intertwine.

Which is why we not only focus on healing relationship with all of those things, but also work on addressing identity, purpose, and values specific to athletes in life after sport.

Meet the Team

Former competitive distance runner turned anti-diet sports dietitian


Food has not always been my friend. Neither has my body.


I started competing in cross country/track & field at 10 years old. I earned my first national title at 15. By the time I was a senior D1 scholarship student-athlete, I was struggling with food, fitness, and my body. Hard.


My decade-long athletic career abruptly ended when a torn hip labrum led to surgery. My body started to change. Restrict/binge patterns became more prevalent (and exhausting). I found myself feeling scared and embarrassed to be around people because I felt so out of control around food, hated my body (and exercising), and I felt like the classic "washed up" athlete who no longer had the athletic accolades to prove my worth. The worst part? I felt so, so, unbelievably lonely.

In short, retiring from sport sucked.

I slowly but surely learned how to navigate all of that through a LOT of trial and error and what felt like last-ditch, radical efforts. Now, I use my experiences to relate to other retired athletes and my clinical expertise to guide them in healing their own relationships with identity, food, movement, and body.

Because food is more than fuel, you are more than a body, and life is more than sport.

Anti-diet & eating disorder dietitian

Hello! I'm so happy you're here.


I specialize in working with adults with eating disorders, disordered eating behaviors, and those who have experienced chronic dieting. I have previously worked at PHP, IOP, and outpatient levels of care for eating disorders with both adults and adolescents.


While I understand the desire to focus on weight loss, it is not the focus of our sessions.

I am a weight-neutral RD and practice from a non-diet, all foods fit, intuitive eating, and Health at Every Size approach, which I believe is crucial when working to restore your relationship with food.


I take a person-centered approach: I see clients as a whole and not as the disorder or issue they wish to overcome. I believe that in order to heal, one must feel seen and understood. I strive to meet clients with compassion exactly where they're at and provide them with tools and information they can learn to use themselves.


My ultimate goal is to help guide you towards freedom from food rules and diet culture and to heal your relationship with food and body. Full recovery from an eating disorder is possible and I would be honored to support you on your journey!


Outside of work, you can find me spending time outside, reading in the park, and playing with my dog. I'm also a somewhat seasoned traveler and have visited over 30 countries - with new food experiences being central to my adventures!
