Hello! I am Renell Kumeh, an advanced practice registered nurse, with dual certification in family medicine and psychiatry, licensed in OR, WA, DC, TX, FL, NV, ND, CT, MA and pending licensures in other states. At the core of my values is treating others the way I would like to be treated.
As a dually certified provider, I offer a unique blend of clinical precision and compassionate, holistic care for both the body and soul. My journey began in 1995 as a nurse, followed by earning my medical degree in 2002 and completing a residency in General Pathology in Postgraduate Education Academy, Kharkov, Ukraine, which provided me with a profound understanding of the biological foundations of health. In 2006, I met my future husband and moved to the United States.
In the United States, I advanced my nursing career, working as a Registered Nurse and becoming a Family Practice Nurse Practitioner (FNP) in 2019. During this time, I managed complex primary care and detoxification protocols for adults and adolescents in behavioral health inpatient settings. In 2024, I achieved my Doctorate in Nursing Practice (DNP) and certification as a Psychiatric Mental Health Nurse Practitioner (PMHNP).
I’m a board-certified psychiatric nurse practitioner passionate about supporting preteens, teens, and adults through ADHD, anxiety, mood disorders, and life transitions. I provide medication management with therapy woven into every visit.
