Maggie Throckmorton, APRN, PMHNP-BC

Co-Owner, Transcend TMS

Maggie Throckmorton, MSN, PMHNP-BC, is a board-certified Psychiatric-Mental Health Nurse Practitioner, certified to treat patients across the lifespan—from children to older adults. She brings over a decade of nursing experience in inpatient psychiatry, detox care, and mental health recovery. In addition to clinical work, she has served as a clinical instructor for nursing students and a preceptor training future PMHNPs. Maggie holds three nursing degrees: an ASN and BSN from Aquinas College of Nursing and an MSN from Vanderbilt University School of Nursing. She is also the founder and owner of SHEchiatry, a private psychiatric practice devoted to women’s mental health.

Maggie integrates traditional psychiatric care with nutritional and functional psychiatry, believing that what fuels the body also fuels the mind. She is especially passionate about non-pharmacological treatments, including NeuroStar Transcranial Magnetic Stimulation (TMS)—an FDA-approved, non-invasive therapy for depression and other mood conditions. Her approach is both evidence-based and holistic, blending cutting-edge science with practical strategies to help patients live optimally—mentally, physically, and emotionally.

Outside of her work, Maggie enjoys traveling, laughing with friends, and spending time with her husband. At home, her Boston Terrier, Dove, truly runs the household—Maggie admits she’s happily wrapped around her paw, but Dove also brings her peace and joy.
