Jacqueline is a Maryland native.  She completed her undergraduate studies with a B.A. in Psychology from St. Mary’s College of Maryland.  She is driven by her passion for clinical work.  Prior to the start of her professional career, she completed an internship working with children with autism in the neuropsychology program at Children’s National in Washington, DC.   She received her Masters of Medical Science from Saint Francis University while completing her certificate of Physician Assistant studies at Anne Arundel Community College.  She graduated with honors in the top 5% of her PA class.  She joined Horizon in 2020 with over 10 years of experience in several subspecialties of medicine.  She started her career at MedStar Good Samaritan Hospital working with Johns Hopkins Orthopaedics.  She worked alongside a fellowship trained Foot and Ankle Orthopaedic surgeon to treat patient in the office setting and spent over 6 years first assisting in the operating room.  She also worked per diem in the urgent care center of the Emergency Department during that time.  She followed her orthopaedic experience with two and a half years in Cardiology at MedStar Union Memorial hospital.  During this time she worked closely with physicians of several subspecialties, including heart failure, structural heart disease, electrophysiology, and sports cardiology.  She performed exercise and pharmacologic cardiovascular stress testing.  In addition, she consulted patients both in the critical care unit of the hospital as well as carried an outpatient patient base.  Jacqueline enjoys the balance between the office and hospital settings to allow continuity of care for her patients.  She values communication with her patients to encourage preventative medicine practices.
