‍
Shelley holds a Master of Clinical Health Sciences and has additional training in nutrition coaching, parental burnout, and the Fair Play method. This background informs her approach to concerns that often overlap in midlife, including sleep disruption, stress, caregiving demands, and the cumulative mental load of work and family life.

Her care emphasizes careful clinical evaluation, appropriate diagnostic testing, shared decision-making, and treatment plans grounded in current evidence and individual patient needs. Shelley sees patients in person at Buoy Healthcare Group's Kirkland clinic and offers virtual consultations throughout Washington state.
