I know how heavy life can feel when you’re carrying pain, uncertainty, or self-doubt. But I believe, as a wise old wizard once said, “Happiness can be found even in the darkest of places, if one only remembers to turn on the light.” My role is to help you find that light again. I work with Gen Z and Millennial adults facing anxiety, depression, trauma, bipolar disorder, ADHD, and more. Through integrative, culturally responsive care, I combine evidence-based psychiatry with holistic strategies to help you feel heard, supported, and empowered to create a life that aligns with your true self.
Hi! My name is Terri Carsley and I have been practicing as a Marriage and Family therapist for the last 16 years. I am a transplant from the East Coast, but have lived in Los Angeles for over 30 years. I have a background in treating addiction and trauma. I am an advanced level somatic practitioner, using both my talk therapy and trauma therapy to help individuals, couples and families achieve healthy communication and heal emotional wounds.
I am a Licensed Marriage and Family Therapist (LMFT) based in California. I graduated from Alliant International University and have 12 years of experience in treatment settings ranging from residential care to routine outpatient care, treating self-harm, addiction, PTSD, anxiety, depression, relation and family conflict, life adjustments and more.
As an African American social worker educated in Alabama, I bring both cultural awareness and a deeply grounded, compassionate approach to my practice. My goal is to create a safe, affirming space where clients can explore their experiences, build resilience, and move toward meaningful change.
My style is collaborative, empathetic, and empowering—I believe in meeting clients where they are while helping them identify their strengths and develop practical tools for growth. I draw on evidence-based practices through a trauma-informed and person-centered lens, supporting clients in navigating challenges such as anxiety, depression, life transitions, identity, and recovery.
Having trained and practiced in diverse communities, I understand the importance of cultural context, lived experience, and social environment in shaping one’s well-being. Whether you’re seeking support for personal growth, healing from trauma, or strengthening coping strategies, I’m here to walk alongside you in the process of building a more balanced and fulfilling life.
I am a highly skilled therapist with a strong focus on trauma therapy, substance abuse, and mental health. I hold dual licensure as a Licensed Marriage and Family Therapist, and as an Associate Clinical Counselor. My educational background includes a Master of Arts in Counseling Psychology from William Jessup University and a Bachelor's degree in Psychology with a minor in Child Development from California State University, Chico.
Hello and welcome! My name is Shannon Merritt and I am a Licensed Marriage & Family Therapist (LMFT). I am based in Southern California and offer telehealth services to clients across the state. My expertise includes supporting individuals through life transitions, managing depression and anxiety, coping with loss, and addressing various mental health challenges. I am also passionate about helping people recover from addiction and/or trauma.
What is your approach to therapy?I draw from various modalities and tailor my approach to each individual and their specific needs. I aim to create a safe and supportive environment where clients feel at ease, can build resilience, and ultimately thrive. My communication style is straightforward, calm, and approachable. I offer clear and honest feedback in order to foster clients' wellbeing while developing hope for their future.
What can clients expect to take away from sessions with you?In our first session together, we'll start with brief introductions, then dive into the specific challenges you're facing. This will help me create a tailored plan for us to work through in follow-up sessions. Clients can expect to develop valuable insight and gain the tools needed to make meaningful changes in their lives.
Georgia Barnes, MSN, FNP-C, PMHNP-BC
I am a dual board-certified Advanced Practice Registered Nurse (APRN) with more than 25 years of clinical experience and board certifications as both a Family Nurse Practitioner and Psychiatric Mental Health Nurse Practitioner. I provide compassionate, evidence-based mental health care for adolescents and adults experiencing anxiety, depression, PTSD, ADHD, mood disorders, and other psychiatric conditions through personalized medication management and supportive psychotherapy.
I believe meaningful mental health care begins with trust, respect, and collaboration. My approach is patient-centered, recognizing that every individual's experiences, strengths, and goals are unique. I work closely with each client to develop a personalized treatment plan that promotes emotional wellness, resilience, and long-term recovery.
My priority is to create a safe, welcoming, and nonjudgmental environment where you feel heard, valued, and empowered to participate in your care. Together, we focus not only on reducing symptoms but also on building healthy coping strategies, restoring balance, and improving overall quality of life. Whether you're facing anxiety, depression, trauma, mood disorders, ADHD, or co-occurring substance use concerns, I am committed to providing thoughtful, evidence-based care that supports your journey toward lasting wellness.
