Trauma and PTSD therapists & psychiatrists in Westlake Village, CA

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.

I hold a Master’s degree in Clinical Psychology from Antioch University, Santa Barbara, California. My practice blends both psychological approach as well as eastern wisdom. With a diverse background of professional and life experiences, I bring empathy, warmth, and a solution-focused mindset to my clients. My goal is to help clients alleviate suffering, boost their productivitiy, and enhance well-being.

I am a bilingual (Spanish & English) marriage and family therapist licensed in California with over 14 years of experience working in clinical practice. I am born and raised in San Francisco's Mission District. I am Salvarodan and Nicaraguan; and a native Spanish speaker. I have served clients experiencing multiple occurring conditions requiring some form of crisis stabilization service or intervention. I have counseled individuals and families dealing with an array of issues such as immigration/deportation, domestic and community violence, teen pregnancy, work – readiness, homelessness, substance abuse, and more. I use a client-centered and strengths-based approach when I work with clients. I believe that it is critical to collaborate with cleints in identifying and attaining what they are seeking. I believe that clients are experts in their lives and I am an expert my field.

It is my prayer to build a practice that helps you reach a place where your mental health is truly at the forefront. My hope is that with each appointment—and each day—you feel supported in moving closer to the best version of yourself.

My work centers on helping clients navigate difficult transitions, strengthen relationships, and reconnect with their capacity for growth and healing. As a social worker with five years of experience, I believe every person deserves to feel heard, supported, and empowered. I’m passionate about creating a space where clients can show up as they are and feel met with compassion, curiosity, and care.
