About Andrew

Dr. Andrew Mendonsa helps people who are feeling stuck, overwhelmed, or unsure about their relationships and identity. He sees people dealing with stress, anxiety, depression, grief, addiction concerns, and intimacy or relationship struggles. He is Dr. Andrew Mendonsa and brings 22 years of experience as a psychologist in California.

Dr. Mendonsa uses straightforward, collaborative work. He listens to what matters most and helps set clear goals. Sessions focus on practical steps you can try between meetings, and on understanding patterns that keep problems repeating.

His background spans community mental health, work with marginalized groups, the criminal justice system, and high-pressure professional settings. That range informs a flexible style that adapts to different life circumstances and pressures.

He draws on several approaches including Acceptance and Commitment Therapy, Attachment-Based methods, Client-Centered practice, Cognitive Behavioral Therapy, and Dialectical Behavior Therapy. Those tools are used to address concerns like shame, compulsive sexual behavior, communication problems, and stress related to work or caregiving.

Dr. Mendonsa is an experienced clinician with licenses in California and Colorado who works in English. He accepts international clients. Before starting, a brief matching questionnaire and scheduling step helps connect you and plan sessions that fit your needs.

How his approaches translate to online work

Acceptance and Commitment Therapy helps people notice painful thoughts and feelings without getting stuck in them, then take actions that match their values. It is often useful for anxiety, depression, and stress when someone wants clearer direction on what matters.

Attachment-Based Therapy looks at how early and current relationship patterns shape trust and closeness. It can help people who struggle with intimacy, commitment concerns, abandonment issues, or recurring relationship conflicts.

Finding the right approach is part of the work together. The therapist will talk with the client about goals, preferences, and life context and then try methods that fit. That decision is collaborative and can change as progress is made.

If you are considering online sessions, confirm the current session options before booking since the biography does not list exact formats. Online work can make it easier to fit appointments into a busy day, shorten travel time, and allow brief check-ins when a quick touchpoint helps keep momentum. It can also let someone choose whether to be on camera or use audio only, which can reduce bandwidth needs or make sessions feel less intense while still allowing meaningful therapeutic work. Licensed professionals can adapt behavioral and values-based exercises, communication skill practice, and coping strategies to an online setting so progress continues between sessions.
