Mercer University School of Medicine conferred the MD in 2010, followed by a transitional-year internship at Cedars-Sinai Medical Center and published research in transplant immunology appearing in Diabetes and the American Journal of Transplantation. Clinical focus areas include mood disorders, psychotic-spectrum conditions, reproductive psychiatry, substance-use disorders, PTSD, personality disorders, and ADHD, with particular specialization in transitional-age youth and college-student populations beginning at age 13. Eating-disorder pharmacotherapy protocols coordinate with dietary-intervention specialists at Nurture & Flow Nutrition for patients requiring concurrent nutritional rehabilitation. Highest-tier services include complex psychopharmacological cross-titration for treatment-resistant psychosis, Spravato-era REMS-compliant prescribing frameworks, and perinatal psychopharmacology risk-benefit analysis for reproductive-age patients.
