Hello, and welcome. I'm Khandice Popley, PMHNP-BC, a board-certified Psychiatric-Mental Health Nurse Practitioner with more than seven years of nursing experience in medical-surgical and psychiatric care.

I believe every person deserves compassionate, respectful, and evidence-based mental health care. My goal is to create a safe, supportive environment where you feel comfortable sharing your concerns and confident that you're being heard.

I work with adults experiencing anxiety, depression, ADHD, mood disorders, trauma-related concerns, stress, grief, life transitions, sleep difficulties, and other mental health challenges. Whether you're seeking care for the first time or returning to treatment, I will work with you to develop an individualized treatment plan that fits your goals, values, and lifestyle.

My approach combines medication management, education, and supportive therapy to help improve symptoms while promoting long-term emotional wellness and resilience.

I'm a Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC) offering compassionate, evidence-based care for adolescents, adults, and older adults. If you're navigating anxiety, depression, ADHD, bipolar disorder, or trauma-related concerns — or simply feeling unlike yourself — you'll be met with compassion, never judgment.

With more than 16 years of clinical experience (7 of them in psychiatry), I specialize in comprehensive psychiatric evaluations, accurate diagnosis, medication management, and individualized treatment plans built around your unique needs and goals. My background spans outpatient private practice, telepsychiatry, and inpatient geriatric behavioral health, so I'm able to support people across a wide range of life stages and concerns.

At Nurelevate, I believe mental wellness is about more than managing symptoms — it's about helping you rediscover balance, build resilience, and thrive with confidence. I'm honored to walk alongside you on that journey.
