Hi, I’m a Board-Certified Psychiatric Mental Health Nurse Practitioner with over 20 years of nursing experience.

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.

Please note that I do not provide disability paperwork, leave of absence documentation, FMLA forms, legal letters, school accommodation letters, or other administrative forms. The only documentation I provide is a work excuse note for the date of your appointment and, when clinically appropriate based on my evaluation and professional judgment, up to three (3) days off from work. 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.

Welcome, and thank you for considering me as a partner in your wellness journey! My therapeutic style is warm, gentle, and supportive, while also being direct and accountability focused. I believe meaningful change happens when compassion and honesty work together. In our time together, we will explore what’s getting in the way of your well-being and identify practical, sustainable ways to improve your daily functioning and overall quality of life.

With over a decade of experience in the mental health field, I bring a grounded, steady presence to the therapeutic space. I support clients through life transitions, emotional challenges, and periods of feeling stuck, always meeting you where you are while helping you move toward where you want to be. Therapy with me is collaborative, intentional, and centered on your goals, your values, and your lived experience. Together, we’ll work toward clarity, resilience, and growth at a pace that feels both supportive and empowering.

I believe people carry far more strength, clarity, and resilience than they often realize. My role is to help you understand the emotional patterns and internal narratives that shape your experience, so you can move through life with greater freedom and self‐trust. I’m engaged, attuned, and honest in the room — offering reflection, insight, and steady collaboration as we explore what’s happening beneath the surface. We work at a pace that feels grounded for you, creating space for real change to germinate.

I offer a space where rigorous thinking and genuine connection work together. I draw on psychoeducation and clinical reasoning to help adults make sense of complex patterns in their relationships, identities, and the systems that shape daily life. I see clients remotely throughout California and Nevada, with one goal: moving you from insight to sustainable progress.
