About Andrew

Dr. Andrew Mendonsa greets people who are feeling stuck, overwhelmed, or unsure how to move forward. He focuses on helping individuals manage stress, anxiety, addiction-related struggles, relationship and intimacy concerns, and identity questions. He keeps sessions practical and direct so people leave with things they can try right away.

With 22 years of experience as a psychologist in Colorado and California, Dr. Mendonsa draws on work in community mental health, the criminal justice system, and high-demand professional settings. He also has long experience supporting people from LGBTQIA+ communities and those exploring kink or nontraditional sexual expression. That background helps him understand shame, secrecy, and the pressure many people feel in both personal and professional life.

In sessions he combines clear problem-solving with attention to personal values and attachment patterns. He uses approaches such as Acceptance and Commitment Therapy and Cognitive Behavioral Therapy to teach skills, and Attachment-Based and Client-Centered ideas to address closeness and trust. He aims for collaboration and concrete goals rather than open-ended therapy.

People who work with him can expect direct conversation about motivation, behavior patterns, and steps to reduce harm and rebuild meaningful routines. He will work with clients to set achievable goals and practical strategies for stress, sleep, grief, or career strain.

For people coming from demanding careers or complex personal lives, he brings a pragmatic mindset and respect for the realities of busy schedules. International clients may be possible; confirm details when arranging sessions.

How his approaches translate to online work

Dr. Mendonsa uses Acceptance and Commitment Therapy to help people clarify what matters to them and take small steps toward those values even when emotions are strong. ACT is often useful for anxiety, stress, and addiction-related patterns. He also uses Attachment-Based ideas to look at how past relationships shape current closeness and trust, which can help with intimacy issues and communication struggles.

Finding the right approach is part of the work together. He will collaborate with each person to decide which methods fit their goals, mixing skill-based strategies and relational exploration as needed. Clients set priorities and try techniques to see what helps most in day-to-day life.

Session logistics should be confirmed before booking because the biography does not specify formats. Online therapy can make it easier to fit appointments into a busy routine, shorten check-ins when time is limited, and reduce the need to travel. Many people find remote sessions helpful for staying consistent while managing work and family demands. Ask about exact session options when you schedule so arrangements match your needs and schedule.
