Marsha Wheatley, MD

Staff Psychiatrist

What has motivated Dr. Wheatley over the course of her career as a caregiver? Dr. Wheatley is a native Houstonian who grew up in a working-class community. Through curiosity and hard work, she was able to attend a university that included people of vastly different life experiences. She was molded by both communities to appreciate the commonalities of humanity. That broad exposure extended her empathetic spectrum to grasp the needs of the American diaspora.

Dr. Wheatley uses a biopsychosocial approach to evaluate the patient. She gathers patient history with a mindset that considers the neuroscience that chemically shapes mood, thoughts, and behavior. She is able to uncover factors that can inhibit psychological growth and development. She has experience in seeing how the social conditions of the “then” can influence the resiliency of the “now”. Dr. Wheatley appreciates, and is proficient in, advances in technology, but prioritizes the analog relationship between doctor and patient.

Meeting people where they are. It is an old trope, but describes how one allows a patient to set the path forward. An open-ended interview is conducted with an open mind towards resolution. When being evaluated and treated by Dr. Wheatley, a patient can expect to be met in a cordial but professional manner. Treatments are discussed and considered based on the mental state of the patient and the clinical efficacy and scientific evidence of benefit. The patient is invited to ask questions and consider whether they wish to pursue the suggested treatment plan.
