About Andrew

Dr. Andrew Mendonsa is a clinical psychologist licensed in Colorado and California with 22 years of practice. He works with adults on stress, anxiety, depression, relationship and intimacy-related concerns, addiction, grief, parenting pressures, career strain, and blended family issues. Sessions are conducted in English and international clients are accepted.

He uses practical, goal-focused methods. Conversations look at what is causing current problems and what can be changed now. He draws on approaches such as Acceptance and Commitment Therapy, Cognitive Behavioral Therapy, Attachment-Based work, and Dialectical Behavior Therapy to shape concrete steps and skills.

Dr. Mendonsa has experience across community mental health, addiction services, the criminal justice system, and corporate settings. That background informs how he talks about workplace stress, high-pressure roles, and transitions. He also works with people from LGBTQIA+ and kink or alternative-sex-culture communities on identity, sexual expression, and related stressors.

When sexual or intimacy-related behavior is causing trouble at work or in relationships, he focuses on understanding motivations and creating realistic change plans rather than shaming. He aims to identify triggers, build coping strategies, and set measurable goals that fit a client's life and values.

Practical problem solving and short-term, results-oriented work are central. He frames therapy as a focused effort to improve functioning and reduce distress, with skills and behavioral experiments used between sessions. To begin, prospective clients complete a short matching questionnaire and schedule an initial session.

How his approaches translate to online work

Acceptance and Commitment Therapy (ACT) focuses on clarifying values and taking committed action toward them while learning ways to live with difficult thoughts. It is useful for anxiety, stress, and life changes where aligning actions with values matters. Cognitive Behavioral Therapy (CBT) breaks problems into thoughts, feelings, and behaviors and uses experiments and skill practice to change patterns that keep someone stuck. It helps with depression, anxiety, sleep, and work-related stress. Attachment-Based Therapy looks at how early and current close relationships shape expectations and reactions. It is helpful for intimacy issues, communication problems, and attachment-related concerns.

Finding the right approach is part of the work. He will collaborate with the client to choose or blend methods that match needs, goals, and preferences. That process usually starts with an assessment conversation and then testing practical techniques to see what fits.

The biography does not list specific session formats, so confirm current options before booking. Online work can make it easier to fit sessions into a busy week, shorten a check-in when time is tight, avoid travel, or choose a session style that reduces camera time. Licensed professionals can deliver the same skill training and behavioral experiments online as in person, and sessions can be scheduled to fit day-to-day responsibilities.
