Irish McCarthy

Second to none in customer care and service.

Born in Hartford, Connecticut, and raised across the U.S., moving frequently. Her mother, sister and brother all migrated to New Mexico, and she followed.

A passionate sports fanatic, Irish lives for fantasy football, dabbles in pickleball, loves hiking, and is an active member of Rotary. Her personal battle with weight sparked a deeper commitment to health and wellness, inspiring her to pursue nutrition education right here at both CNM and UNM.

Before stepping into the world of nutrition, she was a marketing and advertising manager for the Larry H. Miller Group of Companies. She also holds a degree in general business and marketing from Galen College in Fresno, California.

With over 20 years of experience helping individuals achieve their health, nutrition and weight‑loss goals, Irish is driven by a single motto.
