About Andrew

Dr. Andrew Mendonsa meets people where they are and helps them find clearer ways forward. He focuses on stress, anxiety, depression, relationship and intimacy concerns, trauma and abuse, and issues that come up around identity and sexuality. He is a California and Colorado psychologist with more than two decades of practice experience.

He uses a direct, collaborative style. Sessions aim to identify what is getting in the way and to build specific steps clients can try between meetings. That can mean working on behavior changes, learning new coping skills, or looking at patterns in attachment and relationships.

His background includes community mental health, addiction work, the criminal justice system, and consulting with high-achieving professionals. That range informs how he talks about career stress, burnout, and the pressures many clients face at work.

He offers an affirming approach for LGBTQ clients and people involved in kink, alternative sexual cultures, or nontraditional relationship arrangements. He also provides help for those dealing with compulsive sexual behavior and related shame or consequences, focusing on understanding motivations and making practical changes.

Therapy with him is described as collaborative and goal-focused. He draws on methods such as Acceptance and Commitment Therapy, attachment-based ideas, cognitive behavioral approaches, and elements of dialectical behavior and client-centered work. Sessions are aimed at helping people develop tools they can use in daily life.

People interested in starting should be prepared to answer a short matching questionnaire and to schedule sessions according to the therapist's availability.

Approaches that translate to online care

Acceptance and Commitment Therapy, or ACT, helps people clarify what matters most to them and take small actions toward those values even when feelings are difficult. It is often useful for anxiety, stress, and life transitions. Attachment-Based Therapy focuses on how early and current relationship patterns shape how people connect and manage emotion; it helps when intimacy, trust, or attachment wounds are central concerns.

Finding the right approach is part of the work. The therapist discusses goals and preferences with each person and adapts methods collaboratively. That means trying techniques from different approaches and checking in to see what helps most for daily life and relationships.

The biography does not specify which online session formats are offered, so confirm available options before booking. Online work can make it easier to fit sessions into a busy schedule, reduce travel time, allow shorter check-ins when needed, and make it simpler to attend from different locations. Therapists can use the same behavioral exercises, values work, and emotion regulation skills online as in person, and many people find online sessions help them apply new tools directly into their day.
