more about me

Imagine results like these . . .

I’ve lost 23 pounds in 3 months! Working with Sarah has helped me feel hopeful that I can finally reach my weight loss goal. She makes me feel powerful and capable of getting to a healthy place.

Sarah never told me what to do for myself. She let me decide what was best, and thus, I always did more than I committed to!! Sarah NEVER judged me, instead, she worked with me.
L.L.
While working with Sarah, I was able to do my first triathlon in 3 years. Not only that, but I finished 7th in the 50-54 age group, with an overall finish of 131 out of almost 600 racers.
T.W.
As a result of coaching with Sarah, 1) I have lost 14 pounds - a goal I was not able to achieve in years, 2) I have an eating plan I can rely on that works, and 3) I have cut back on alcohol. Life is so much better.
B.P.
Sarah really took time to listen to me, then offered a potpourri of solutions to help me break my negative behavior cycles. She helped me to incorporate habits that made me feel like the best version of myself.
C.R.
Before I started working with Sarah, I was either “on” or “off” a diet. I didn’t know how to make good food choices or how to incorporate healthy eating into my day-to-day life. Sarah changed that.
