ADHD therapists and psychiatrists in Thousand Oaks, CA

I'm a Licensed Marriage and Family Therapist based in Sonoma County with six years of clinical experience working with young people and families. I've worked across a range of settings including intensive residential treatment, county behavioral health, and outpatient care, and I bring that breadth of experience into my private practice. I specialize in working with preteens, teens, young adults, and families navigating anxiety, trauma, identity, family conflict, and life transitions. I also work with couples on a private pay basis.

I’m a licensed therapist with a background in supporting adults and teens through anxiety, trauma, life transitions, and relationship stress. I earned my graduate degree in counseling and have worked in both community-based and private practice settings, which has helped me understand the real-life pressures people carry—work, family, finances, identity, and burnout.

My style is practical and compassionate: we look at patterns, the stories you’ve learned to live by, and what it would feel like to respond differently—more grounded, more empowered, and more like “you.” I often integrate inner child work, trauma-informed care, and skills for emotional regulation and ADHD/executive functioning.

I primarily work with adults who want to improve communication, rebuild trust, and create more secure connection.

As a Psychiatric Mental Health Nurse Practitioner, I aim to create a space where you feel heard, respected, and understood. I believe mental health care should be collaborative, practical, and tailored to your unique needs. My approach combines evidence-based treatment with real-life understanding whether that includes therapy, lifestyle changes, or medication management when appropriate. I value honesty, cultural awareness, and meeting you where you are. My goal is to help you feel more stable, confident, and in control of your mental health not just during appointments, but in your everyday life.

I bring a wealth of experience from my work in child welfare for nearly 10 years, which has shaped me into a deeply trauma-informed practitioner. Over the years, I have supported clients of all ages and walks of life, including individuals facing complex socioeconomic stressors and diverse life circumstances. I am comfortable working with a wide range of mental health concerns, from mood disorders like anxiety and depression to more complex personality-based struggles. No matter your background or the challenge you are facing, I offer a stable, professional, and non-judgmental presence designed to help you process your experiences and move toward a healthier future.

I believe that therapy is a partnership, and my goal is to provide a safe, non-judgmental space where you feel truly heard. As a licensed clinical social worker, I specialize in supporting individuals as they navigate life’s transitions, stress, and anxiety. My approach is rooted in compassion and evidence-based practices, primarily utilizing Cognitive Behavioral Therapy (CBT) and a client-centered perspective to help you develop practical tools for your daily life. I am dedicated to working alongside you to build on your existing strengths, foster resilience, and help you create the change you are seeking. You don’t have to navigate these challenges alone; I invite you to reach out so we can start this work together.

My clients should know that I truly care about their well-being and take the time to listen. I want them to feel comfortable, respected, and never rushed. I believe in providing care that is compassionate, thorough, and personalized to their needs. I also value honesty, trust, and clear communication, so clients feel informed and supported every step of the way.

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.

Great to meet you!

As a licensed clinical social worker and psychotherapist, I believe prioritizing mental health is key to happiness and overall well-being. Seeking help can be very difficult, so congratuations on taking that first step! I've been working to help teenagers and young adults over the past 15 years and look forward to supporting you in this journey!

I am a board certified, doctoral prepared PMHNP. I completed my post graduate at National University in Adult, Child and Adolescent Psychiatry. I earned my DNP from Azusa Pacific University and graduated from CSUSB MSN program. I have been a faculty at CSUSB since 2014. Extensively trained and a certified Trauma-Informed specialist. I diagnose and treat mental disorders including medication-assisted treatment along with counseling for chemical dependency and substance use disorders.

I work with adults and teens navigating trauma, burnout, identity, and the particular exhaustion of being a sensitive person in a fast-changing world. My work goes beyond talk therapy to build a flexible nervous system, helping to regulate it, reduce symptoms of trauma, and build resilience.

Many of the people I work with are doing everything right on paper. They are the ones who keep showing up, holding it together, being the person everyone else leans on. And they are exhausted in a way that is hard to explain to the people around them. They worry they are making the wrong choices or that everyone else has it together.
