Nutrition Philosophy: Using a whole-person approach, I help my clients learn how to care for and fuel their bodies to support both physical and emotional wellbeing. I help my clients learn how to support their digestion through an individualized, total lifestyle approach.

Programs: Nutrition Counseling Package and Nutrition Presentations

Hi! I’m Catherine. My interest in nutrition began during my freshman year of college when my soccer coach taught our team about the impact of fuel on athletic performance. I transferred to Winthrop University my junior year to pursue my undergraduate degree in Human Nutrition and went on to complete my dietetic internship through Winthrop with rotations around Columbia, SC.

I started my dietetics career almost a decade ago in clinical nutrition and food service, but I soon realized I desired to develop long-term relationships with clients to help foster behavior change. While working in an outpatient nutrition clinic, I completed my Masters degree in nutrition with my thesis on corporate wellness program implementation and success. I worked in corporate wellness coaching and nutrition counseling for over five years with clients such as BMW supporting clients in improving their wellbeing through sustainable habit change.

I love helping clients with many goals and conditions, and my nutrition passion is digestive health. Throughout the years, I have spoken with many clients who feel frustrated and confused regarding their gastrointestinal health and I help my clients learn how to support their digestion through an individualized, total lifestyle approach.

I help people address their health concerns by working together to form personalized, achievable habits to feel their best. I aim to meet clients where they are without judgement and help them feel confident in their nutrition knowledge as we work together to improve their health!
