About Andrew
Dr. Andrew Mendonsa offers a direct and steady presence for people facing stress, anxiety, depression, addiction, and identity-related questions. He is a clinical psychologist with more than two decades of experience and practices from California.
His style is straightforward and collaborative, aimed at helping people make practical changes they can live with. He draws on existential ideas to help people find meaning in hard moments and clarify what matters most.
Background and approach
He also uses Acceptance and Commitment Therapy and cognitive-behavioral techniques to turn insights into everyday steps. Sessions are focused on clear goals and skills you can use between meetings. His background includes work across community mental health, addiction services, criminal justice settings, and corporate environments.
That range informs a flexible approach for people who carry shame, grief, or high pressure from work and life circumstances. He also has experience supporting people navigating sexual identity, kink and alternative sexual cultures, and concerns around problematic sexual behavior. In the room he helps clients identify what motivates their choices, reduce guilt, and rebuild routines that feel sustainable.
He balances practical coping tools with conversations about values and connection. The aim is often to reduce symptoms and to help clients move toward a life that feels more honest and manageable. People who reach out can expect a therapist who blends realistic strategies with deeper questions about purpose and identity.
Dr. Mendonsa works in English and sees people who live in or outside the United States.

Online support
Therapeutic approaches for online work
Dr. Mendonsa uses existential therapy to ask practical questions about meaning, purpose, and personal values; this helps when life changes or identity questions feel overwhelming. He also integrates Acceptance and Commitment Therapy (ACT) to teach ways of living with difficult thoughts and feelings while moving toward valued goals. Attachment-Based Therapy informs how he looks at patterns of connection and communication that affect relationships and intimacy.Choosing the right approach is part of the work. He will talk with each person about what feels most useful and adapt methods to fit the person's needs, goals, and preferences. That collaborative process helps make sessions feel relevant from the start.
Online sessions are offered as video calls, phone sessions, live chat, or text-based messaging to make therapy easier to fit into daily life. Video calls work well for deeper conversations and visual connection. Phone sessions can be simpler when bandwidth is limited or when someone prefers not to be on camera. Live chat and text messaging offer brief check-ins or ongoing support between longer sessions. These options help people access therapy with more flexibility and fewer scheduling barriers.
