Board Certified Psychiatric Physician Assistant

Working in healthcare since 1997, board-certified physician assistant Mandie Anderson has possessed a lifelong passion for the practice of medicine. While completing her Master's in Medical Science at Midwestern University's PA program, she took a special interest in neuropsychiatry. Since 2011, Mandie has provided full-time, office-based psychiatric services, then spent a year in the emergency department before returning to her true passion of mental health. Mandie obtained her Certificate of Added Qualifications in psychiatry through the National Commission for the Certification of Physician Assistants in October 2016, furthering her specialization in the field she loves.

Mandie frequently performs pharmacogenetic and laboratory testing to identify contributing factors toward patients' symptoms, and she wholeheartedly advocates addressing the often neglected mind-body connection. She is an adjunct professor for NAU, Midwestern University, and A.T. Still University's physician assistant programs, and she precepts PA students from A.T. Still, NAU, Midwestern, and Yale PA programs, as she strongly believes that the best solution to the psychiatric healthcare shortage is to create more providers! 

Her clinical work history also includes hospital neurology, physical medicine & pain management, and psychiatric consulting for a local Department of Corrections.

Mandie sees adolescents and adults ages 16 and up.


Board Certified Physician Assistant

Jessica is a board-certified physician assistant who first joined us as a PA student in early 2018, while completing her clinical rotations.  This experience sparked in her a deep appreciation for the field of behavioral health. She previously completed her Bachelor’s in Elementary Education from Central Michigan University and worked in education for seven years, prior to pursuing her passion for the field of healthcare. She completed her Master's of Science in Physician Assistant Studies at A.T. Still University in 2018, and we brought her on board the very moment we could! She demonstrates an infectious motivation to deliver whole-person care. In her free time, she enjoys travelling, running, and exploring the outdoors.


Medical Assistant

Sherri and Mandie first began working together in February of 2010 at Arizona Neurological Institute, where Sherri managed three medical providers herself!  Whether it's taking your call, meeting all your patient needs, or just entertaining you with her chipper personality and delightful singing voice, she is everything a provider could wish for in a medical assistant, and more! We all feel truly blessed to have her complete the Pinnacle Team.
