We have helped hundreds of people within all levels of treatment get through it by developing EFFECTIVE nutrition restructuring & rehabilitation plans that work! Nutrition re-stabilization is the cornerstone in ED recovery; those who achieve it have far greater and more sustainable outcomes than those who do not.

We work with adolescents and their families as well as adults of all ages. To accommodate those with busy weekday schedules, our clients appreciate the scheduling flexibility they have with evening and weekend appointment as well as virtual options. We utilize a HIPAA & PCI-Compliant Virtual/Telehealth platform so if you are stuck at work, in traffic, can't find child care, or don't have a qualified provider where you live, rest assured you can have your nutrition counseling sessions wherever you can connect to the internet.

We have functioned as proactive members of multiple clinical nutrition and interdisciplinary care teams. We develop and manage nutrition care plans for the most complex patients and have been known to develop and recommend creative ways to motivate proper food and fluid intake. Eating disorders can be quite unpredictable, therefore without the right experience they can be very challenging to treat.
