Find a psychiatrist in El Cajon, CA — covered by insurance

For the past year, I've worked with adults facing serious mental health challenges at one of Los Angeles's largest public health systems, and what I've learned is that lasting change comes from relationships built on trust. Now I'm bringing that experience into private practice, where I can focus on what matters most: your individual progress. I work with people navigating anxiety, depression, and PTSD, and I offer flexible evening and weekend availability via telehealth throughout California. As a PMHNP, I'm here to support your whole mental health journey.

I assess mental health concerns, diagnose conditions, prescribe and manage psychiatric medications, and provide psychotherapy.

Hi, I’m Mercy Nyeche, DNP, PMHNP-BC. I’m a board-certified Psychiatric Mental Health Nurse Practitioner dedicated to helping adults regain clarity, confidence, and emotional balance.

Reaching out for support can feel overwhelming especially when you’re used to being the strong one for everyone else. Whether you’re navigating anxiety, depression, burnout, life transitions, or feeling stuck in patterns that no longer serve you, you don’t have to do it alone.

My approach is compassionate, collaborative, and evidence-based. I take time to truly listen, understand your goals, and create a personalized treatment plan that fits your life, not just your symptoms.

If you require any of the services or documentation listed above, I kindly ask that you schedule with another provider who offers those services. Thank you for your understanding and for helping ensure that your healthcare needs are matched with the appropriate provider.
