Olivia incorporates mindfulness, lifestyle modifications, and nutrition into her medical practice.

Olivia completed her Bachelor of Science in Nursing from James Madison University in Harrisonburg Virginia. Olivia then continued her education and graduated with her Master’s in Nursing from Regis College in Wellesley Massachusetts. During her education, Olivia received specialized training in psychopharmacology from Harvard University-educated physicians.

Her training includes residential eating disorder treatment and inpatient psychotic disorders. Olivia believes in a comprehensive and collaborative approach while caring for her patients.
