Dr. Stoddard earned his medical degree from the University of Arizona College of Medicine - Tucson and completed his residency at the University of Arizona College of Medicine - Phoenix. He is board-certified in psychiatry and provides care for adult patient populations. Prior to his career in medicine, he proudly served in the U.S. Air Force.

Although Dr. Stoddard specializes in medication management of psychiatric conditions, supportive psychotherapy is often incorporated into his visits, as he believes a combined approach leads to a more robust treatment response. Additionally, he aims to enhance wellness through discussion of lifestyle modifications that emphasize quality sleep, a healthy diet, and regular exercise.

Initial appointments consist of a psychiatric evaluation and discussion of evidence-based treatment options. If telehealth is deemed to be an appropriate modality and pharmacotherapy is recommended, discussion will consist of selecting a suitable medication to address target symptoms while minimizing adverse effects. Follow-up visits focus on assessing treatment response and adjusting regimens to optimize outcomes.
