About Andrew

Dr. Andrew Mendonsa is a clinical psychologist licensed in Colorado and California with 22 years of experience. He focuses on stress, anxiety, depression, addictions, relationship and intimacy-related concerns, and issues common in LGBT communities. He also addresses self-esteem, grief, sleep problems, parenting questions, career strain, and coping with life changes.

Andrew describes a collaborative and goal-focused way of working. He uses Emotionally-Focused Therapy alongside approaches such as Acceptance and Commitment Therapy, attachment-based methods, client-centered work, and cognitive behavioral techniques. Sessions aim to identify what drives patterns of behavior and then develop practical strategies to change them.

He has worked across community mental health, addiction services, the criminal justice system, and with high-achieving professionals in business and academia. That range has shaped his practical style and familiarity with the stresses of different life settings. He also brings experience with issues around adoption and foster care, aging and geriatric concerns, chronic illness and pain, caregiver stress, and cancer-related distress.

Mendonsa works with people facing problematic sexual behavior, kink and alternative sexual cultures, codependency, commitment and communication problems, and complex attachment concerns. He frames work around clear goals and measurable steps rather than open-ended treatment.

Sessions use a subscription model that can be canceled at any time. International clients may be accepted and sessions are offered in English. Prospective clients are asked to complete a short matching questionnaire and schedule a first session using the site’s online options.

How his approaches translate to online work

Emotionally-Focused Therapy (EFT) focuses on recognizing and naming emotions and how they shape patterns in close relationships. It can help people notice hard-to-name feelings and how those feelings affect connection and communication.

Acceptance and Commitment Therapy (ACT) centers on noticing thoughts and feelings without getting stuck in them, and on clarifying values to guide practical steps. It is often useful for anxiety, depression, and motivation-related concerns.

Attachment-Based Therapy looks at early and current relationship patterns to understand how people connect and respond to others. It can be relevant for intimacy concerns, abandonment, and attachment issues.

Finding the right method tends to be collaborative. The therapist will discuss goals, preferences, and what feels most useful, then adapt techniques across these approaches to fit each person’s needs.

The profile does not specify session formats, so confirm current options before booking. Online sessions can make it easier to fit therapy into busy schedules, shorten travel time, and allow workday check-ins. Some formats require less bandwidth or can be done without video, which can suit shorter check-ins or people who prefer not to be on camera. Licensed professionals can work with international clients, but check specific session details when you schedule.
