Why we started Athletic Foundations

AF started with a question. Actually, it started with a bunch of questions we've received over the years from our colleagues and friends who had sports nutrition questions for their athletes:

What should Peter drink before a game?

What should Lily eat after practice?

How many meals should Billy have during a triple-game tournament day?

We realized that lots of teams, gyms, physical therapy practices, and individual coaches who train athletes want to provide sports nutrition or recovery guidance to their athletes. But they don't have the time to search for, build and provide evidence-based resources. Nor do they have the budget to hire a full time sports dietitian.

So as sports dietitians and exercise physiologists who have worked with Olympians and athletes in the NFL, NBA, NCAA, USTA, and other professional organizations, we decided to tap into the knowledge we've gained and offer evidence-based sports nutrition solutions at a price that can be scaled up as your practice or team grows.

We created Athletic Foundations to give developing athletes—and their coaches—the answers they need.

Our mission is to enable coaches to empower athletes to live and perform at their best. We hope you’ll join us.

Meet the Founders

Tiffany Chag, MS, RD, CSCS, CPT

A former Division 1 soccer player, Tiffany knows firsthand the payoffs of consistent hard work. She also knows that optimal performance and a healthy lifestyle are achievable with the right kind of support.

Tiffany is based outside Boston where she runs a private nutrition and training company. She has also worked as an exercise physiologist and sports dietitian in the Sports Performance Center at the top-ranked Hospital for Special Surgery in NYC, and as the dietitian at TB12, where she revamped the company’s nutrition philosophy to be more evidence-based.

She completed her master’s degree in exercise physiology and nutrition from Teachers College, Columbia University.

Tiffany still loves putting her body to the test and has completed several marathons, triathlons, and uncomfortably long bike rides, including to raise money for cancer research. Her favorite exercise is the pull-up.

Jason Machowsky, MS, RD, CSSD, CSCS, CEP

After starting his career as an engineer and IT consultant, Jason switched gears in his mid-twenties to follow his passion for movement and nutrition. He returned to school and completed his master’s degree in exercise physiology and nutrition from Teachers College, Columbia University.

Jason is currently based in the New York City area and runs his own private nutrition and training company. He has also worked as an exercise physiologist and sports dietitian in the Sports Performance Center at the top-ranked Hospital for Special Surgery in NYC and was the instructor of the Sports Nutrition Practicum at Teachers College, Columbia University.

He serves our nation’s athletes as a member of the United States Olympic Committee Sports Dietitian Registry and has provided sports nutrition services for two Division 1 NCAA schools.

Today, Jason’s fitness routine includes trying to get back to lifting heavy things like he did in his 20’s; maintaining endurance through chasing his kids everywhere; and daydreaming about getting back to tennis, playing the guitar, and cooking for fun when he no longer has to chase his kids everywhere.
