Dietitian vs. nutritionist
Which do you actually need?
A Registered Dietitian (RD) is a credentialed health professional who has completed accredited training, supervised practice and a national exam, and can provide medical nutrition therapy. A nutrition coach or nutritionist can be a great resource for everyday habits and accountability too — it's a different credential with a different scope. For medical nutrition needs, you want an RD, and ours is on-site, downtown.

Common questions
Nutrition, answered.
What’s the difference between a dietitian and a nutritionist?
A Registered Dietitian has completed accredited clinical training and can provide medical nutrition therapy. A nutrition coach or nutritionist is a great resource for everyday habits and accountability — a different credential, a different scope. Our resident practitioner is a Registered Dietitian.
Do I need to be a member?
No — the resident RD sees clients who aren’t gym members. Members get seamless, one-roof coordination with their trainer.
Do you help endurance athletes and over-40 muscle goals?
Yes — performance and endurance nutrition, plus healthy-aging and body-composition support, are core focuses.
