Johnna Hartenstine, MCN, RDN, LD is known for her down-to-earth
yet direct, kind, and supportive approach with her patients. Her
primary focus is eating disorder treatment from an all foods fit
philosophy working towards mending one's relationship with food.
Additionally, she focuses on nutrition counseling for oncology & renal
conditions as well as general nutrition.

She integrates this with an evidence-based approach rooted in
medical nutrition therapy. This provides the right mix of creative and
logical understanding to one's own health journey. Her global culinary
perspective stems from her time living & traveling in Europe & Australia as well as the United States.

degree in Molecular and Cellular Biology from the University of
Arizona in Tucson, AZ. This led her to pursue a deeper understanding
of the role of nutrition at all stages of life & medical ailments through

Southwestern's Coordinated Program.

She previously worked with clients at Center for Discovery as their
national virtual dietitian for all levels of care (RTC, PHP, IOP) as well
