Kim Clifford, PA-C
Kim is a certified physician assistant specializing in adult ADHD and integrative psychiatric care. Originally from Colorado, she completed her bachelor’s degree in Sport & Exercise Science at the University of Northern Colorado, earned a graduate certificate in Public Health from OHSU, and completed her PA training at Heritage University in Toppenish, Washington.
Kim spent seven years practicing emergency medicine in Portland, building a strong foundation in acute care, patient advocacy, and trauma-informed practice. During the COVID-19 pandemic, she experienced significant burnout in the emergency department and became increasingly disillusioned with the constraints of large hospital systems. This led her to transition into outpatient psychiatry, where she could practice more relational, patient-centered care and support individuals over time rather than only in crisis.
Kim has experience in both traditional outpatient psychiatry and ketamine-assisted psychotherapy. She completed the Neuroscience Education Institute’s Master Psychopharmacology Program and has pursued additional advanced training in functional psychiatry with a focus on ADHD. Kim is passionate about ongoing learning and staying current with the latest developments in psychiatric research and treatment. After witnessing firsthand the barriers her husband, family members, and others in her community faced when trying to access mental health care, she founded Tidal Health NW to offer accessible, individualized, and compassionate care for her patients.
Before becoming a PA, Kim worked as a massage therapist in integrative medicine clinics—experience that shaped her appreciation for both Eastern and Western approaches and continues to inform her functional, whole-person approach.
Kim has a long history of community service. She began volunteering as a massage therapist at Outside In, supporting youth and houseless community members, and later transitioned into medical outreach through street medicine. For the past eight years, she has provided direct care and harm-reduction–focused support to individuals experiencing houselessness throughout Portland. This work deeply informs her practice philosophy, including her commitment to accepting Medicaid plans and offering sliding-scale cash options—ensuring that high-quality mental health care remains accessible regardless of financial circumstances.
Kim is licensed in Oregon and Washington and is currently accepting new patients and is in-network with Moda, Regence BCBS Oregon, Cigna, Aetna, and select CareOregon plans.
