About Douglas
Dr. Douglas Treese is a psychologist practicing in Arizona with more than three decades of clinical experience. He holds a PhD in Counseling Psychology and is licensed as an Arizona Psychologist (PSY-001646).
He meets people where they are and focuses on clear, practical steps people can use to feel better in daily life. He uses the Gottman Method alongside therapies that emphasize values, thoughts, and attachment. Sessions begin by mapping what causes distress or what someone wants to change.
Background and approach
That gives a clear plan for what to work on together. Dr. Treese draws on Acceptance and Commitment Therapy and Cognitive Behavioral Therapy to help people notice unhelpful thoughts and choose actions that match their values.
He also uses attachment-based and client-centered ideas to build stronger emotional connection and understanding in relationships. These approaches are used to address stress, anxiety, depression, grief, and problems with self-esteem. Over 36 years he has practiced in hospitals, managed care settings, and independent practice.
He brings that experience to work through issues such as addictions, trauma and abuse, eating concerns, bipolar disorder, and coping with life changes. Additional focus areas include abandonment, communication problems, divorce and separation, and family of origin issues. Sessions are offered in English and international clients are accepted.
He aims for straightforward collaboration - mapping problems, agreeing on changes, and supporting steps to maintain improvements.

Online support
Therapeutic approaches adapted for online care
Dr. Treese commonly integrates the Gottman Method, Acceptance and Commitment Therapy (ACT), and attachment-based ideas in online work. The Gottman Method focuses on improving communication and managing conflict patterns to help people relate more constructively. ACT helps people notice their thoughts and choose actions that match their values instead of getting stuck in avoidance. Attachment-based work looks at how early emotional bonds shape reactions and helps people build more supported ways of relating.Choosing the best approach is a collaborative process. The therapist will review goals, history, and current challenges and then recommend techniques that fit the person’s needs and preferences. That plan can be adjusted as work progresses so sessions stay focused on what is most helpful.
Online formats include video calls, phone sessions, live chat, and text-based messaging to increase flexibility. Video calls allow face-to-face conversation and visual cues. Phone sessions can be simpler when bandwidth or location makes video difficult. Live chat and text can be used for brief check-ins, step-by-step tools, or ongoing support between longer sessions. These options make it easier to schedule care around work, school, or travel while keeping the same therapeutic aims.
