About
Hi, I’m Dr. Andreas Marwick. Originally from New Zealand, I specialize in working with adults aged 20-50 — Whether you're navigating anxiety, depression, anger, relationship challenges, or just a deep sense of “something’s not quite right,” I’m here to help you untangle what’s going on and move forward. My approach is compassionate, collaborative, and rooted in the belief that therapy should feel like a safe space where you can show up exactly as you are—no judgment, no pressure. I offer telehealth services throughout California, making therapy more accessible no matter where you are located. With a focus on telehealth services, I provide convenient and accessible therapy to individuals across California, ensuring that distance is never a barrier to receiving quality mental health care. I'm Dr. Andreas Marwick, a passionate and dedicated clinical psychologist committed to helping individuals navigate life's challenges and find their path to fulfillment and well-being. Specialties: I specialize in working with adults aged 20-50 who are navigating anxiety, depression, anger, relationship challenges, or a sense of "something's not quite right". During initial sessions, we strike a balance between a quality assessment and practical steps you can take to make changes. Most of my clients see an improvement of symptoms within the first six sessions. Credentials & Experience: I have over 10 years experience helping adults and older adults in a private practice setting to manage low mood, anxiety, relationship challenges, health conditions and pain, as well as substance use difficulties. I am licensed in both California and New Zealand.
"My therapeutic approach is collaborative, compassionate, and culturally sensitive. I believe in creating a non-judgmental space where you can openly explore your thoughts, feelings, and experiences. Drawing from cognitive-behavioral therapy (CBT), acceptance and commitment therapy (ACT), and compassion-focused therapy (CFT), I tailor my interventions to meet your individual needs and goals."
