When appropriate, we also work alongside physicians, pediatricians, and other healthcare professionals to support coordinated care.

Laura Walsh, RDN, LDN, CPT
President and Founder, Walsh Nutrition Group, Inc.
Laura Walsh is a registered and licensed dietitian nutritionist, culinary dietitian, and ACE-Certified Personal Trainer. She founded Walsh Nutrition Group in 1999 to give clients highly individualized nutrition guidance that connects sound science with the realities of everyday life.
