About Andrew
Dr. Andrew Mendonsa is a clinical psychologist licensed in Colorado and California with 22 years of experience. He works with adults facing stress, anxiety, depression, relationship and intimacy concerns, addiction-related problems, grief, sleep trouble, parenting strain, career transitions, and issues tied to sexual identity and kink culture. He also addresses compassion fatigue and caregiving stress.
He uses straightforward, goal-focused work. Sessions center on identifying unhelpful thoughts and habits, trying practical skills, and measuring small changes over time. Cognitive Behavioral Therapy is one of the methods he uses alongside Acceptance and Commitment Therapy and attachment-based ideas. Dialectical Behavior Therapy and client-centered methods inform his style when emotion regulation and values clarification are needed.
Andrew draws on two decades of work across community mental health, addiction services, criminal justice, and corporate settings. That range shapes his practical approach with people who face both everyday pressures and complex situations. He aims to help clients set clear goals and learn tools they can use between sessions.
He has worked with people navigating sexual shame, compulsive sexual behavior, kink and alternative sexual cultures, and LGBTQ concerns. He also helps those coping with medical illness, chronic pain, adoption and foster care issues, attachment and personality-related challenges, and relationship communication problems.
Sessions are conducted in English and he accepts international clients. Cost varies by location and sessions use a subscription that can be canceled at any time. To begin, choose the See online therapy options button, complete the short matching questionnaire, and schedule a first session.
How his approaches translate to online sessions
Dr. Mendonsa commonly uses Cognitive Behavioral Therapy to help people identify unhelpful thoughts and test new ways of responding. CBT breaks problems into manageable parts - thoughts, feelings, and behaviors - and teaches concrete skills for change. Acceptance and Commitment Therapy focuses on clarifying values and taking action toward them while accepting difficult feelings, which helps with life transitions and chronic stress. Attachment-Based Therapy looks at patterns in close relationships and how early bonds shape current trust and intimacy issues; it can help with relationship and intimacy concerns.Choosing the right approach is collaborative. He works with each person to match methods to their goals, preferences, and what they’ve tried before. That means trying skills, checking what helps, and adjusting the plan over time rather than committing to one single method from the start.
Session formats are not listed in the biography, so confirm current online options before booking. Online work can make it easier to fit sessions into a busy life - for example, shorter check-ins during a work break or sessions that avoid a commute. It also lets people continue care when they move or travel. Practical benefits include easier scheduling, using exercises between sessions, and keeping momentum on concrete goals without requiring frequent in-person visits.
