About Andrew
Dr. Andrew Mendonsa helps people facing stress, anxiety, depression, addiction, and struggles with self-esteem. He works with concerns such as intimacy, relationship challenges, grief, sleep problems, parenting strain, career transitions, and compassion fatigue.
He brings 22 years of clinical experience to each session. Dr. Mendonsa is a licensed psychologist in Colorado (CO Psychologist PSY.0005062) and California (CA Psychologist PSY23208).
He uses straightforward, practical methods in therapy and often draws on Emotionally-Focused Therapy alongside acceptance and behavior-focused approaches.
Background and approach
Sessions are conversational and goal-focused. Clients can expect clear steps and tools they can use between meetings. His background includes work in community mental health, addiction services, criminal justice settings, and the personal sector.
That range informs how he addresses shame, performance pressure, and complex life stress. He also supports people navigating sexual expression, kink, and nontraditional relationship dynamics without judgment. Therapy with him tends to emphasize understanding emotions, improving communication, and building coping skills.
He blends client-centered listening with evidence-based techniques to create a tailored plan. The aim is practical change rather than open-ended treatment. Sessions are offered in English and are available to international clients.

Online support
How therapeutic approaches translate to online work
Emotionally-Focused Therapy focuses on identifying and working with emotions to improve connections and reduce distress; it is often helpful for people wanting clearer emotional understanding and better communication. Acceptance and Commitment Therapy (ACT) helps people notice unhelpful thoughts and commit to actions that reflect their values, which can aid with anxiety, depression, and life changes. Attachment-Based Therapy looks at how early relationships shape current patterns and helps people build more reliable ways of relating and coping.Finding the right approach is part of the work. He will talk with each person about their goals, preferences, and what has or hasn’t helped before. Together the therapist and client decide which methods to use and adjust the plan as progress is made.
Online sessions are offered by video call, phone, live chat, and text-based messaging to provide flexibility. Video works well when visual cues and deeper conversation matter. Phone sessions can be quieter or easier when bandwidth is limited. Live chat and text messaging suit short check-ins, brief coaching, or work between sessions. These options help people fit therapy into busy lives and different schedules.
