I specialize in treating the full spectrum of eating disorders in both adults and adolescents. I began my work at the residential treatment level of care working with both adult and adolescent eating disorder patients. I then widened my experience and furthered my skills by working in the outpatient setting.

Since that time I have worked as the lead dietitian at the residential treatment level of care treating adolescents with severe eating disorders.

My specialty and expertise is working with clients who have seen dietitians before and are looking for something different-more individualized care, incredibly personal, and someone they can trust.
