Theresa Shank is also Lancaster’s Dietitian

After five successful years of counseling clients in the Philadelphia and surrounding suburban areas, Theresa was presented with the chance to grow the Philly Dietitian brand to her hometown of Lancaster, Pennsylvania. By launching Lancaster Dietitian, she would be able to promote a healthy and balanced lifestyle in the place where her dreams of fundamental nutrition and overall wellness began.

It was I Am Limitless that gave her the opportunity to expand her reach to her hometown. She went in for a spin class with her Aunt, and left feeling inspired, having experienced the same values and principles that she aspired to provide to her own clients. It only took one visit to I Am Limitless for Theresa to realize that it was a wellness community with which she wanted to align her practice.
