About Douglas
Dr. Douglas Treese is an Arizona psychologist with a PhD in Counseling Psychology and 36 years of experience. He works with adults on issues such as anger, stress, anxiety, depression, grief, addictions, and relationship concerns.
He uses plain language and practical steps to help people figure out what to change and how to do it. He begins by mapping what is causing the difficulty or what the person wants to improve.
Background and approach
That helps set clear, realistic goals. Then he looks at the psychological and behavioral changes that can move someone toward those goals. Sessions focus on small, repeatable steps that build toward lasting change.
Dr. Treese draws on several approaches, including Acceptance and Commitment Therapy, Cognitive Behavioral Therapy, Attachment-Based Therapy, Emotionally-Focused Therapy, and Client-Centered Therapy. He tailors methods to each person’s needs instead of following one single model.
Conversations are collaborative and practical rather than abstract. His background includes work in psychiatric hospitals, managed care agencies, and independent practice. That variety shaped his ability to handle both crisis moments and longer-term planning.
He helps people build skills they can use outside sessions. Sessions are offered in English and he accepts international clients. He supports people who want help with mid- and later-life adjustment, coping with loss, strengthening self-esteem, and addressing substance issues.
The focus is on clear planning, behavior change, and keeping those changes going.

Therapeutic approaches and online care
Acceptance and Commitment Therapy (ACT) helps people notice difficult thoughts and feelings without getting stuck in them, then commit to actions that match their values. It can be useful for anger, anxiety, and stress where avoidance or fusion with thoughts is a problem. Cognitive Behavioral Therapy (CBT) focuses on spotting unhelpful thinking and testing new behaviors. CBT is often used for anxiety, depression, and managing angry reactions by teaching practical skills to change patterns.Finding the right approach is part of the work. The therapist will collaborate with each person to choose methods that fit their goals and preferences. That might mean combining ACT with CBT techniques or using attachment-focused ideas when relationship issues are central.
Online therapy offers flexible ways to meet. Video calls let people work visually through emotions and body language. Phone sessions work well when bandwidth is limited or a quieter check-in is needed. Live chat or text-based messaging can be used for shorter check-ins, homework support, or when typing feels easier than speaking. These options make it simpler to fit sessions into a busy life and to continue work between meetings.
