About Douglas
Dr. Douglas Treese is a psychologist based in Arizona who centers his work on helping adults face life’s difficult moments. He uses practical conversation and focused planning to address issues like anxiety, depression, stress, grief, and addictive behaviors.
He brings 36 years of clinical experience to sessions and holds the credential AZ Psychologist PSY-001646. He trained in counseling psychology and has worked in psychiatric hospitals, managed care settings, and independent practice.
Background and approach
That background informs a steady, experienced approach to common struggles such as relationship difficulties, self-esteem concerns, eating issues, bipolar mood patterns, and coping with life changes. His sessions begin by mapping the problem or the life area a person wants to improve. Together the therapist and client identify what needs to change and make a step-by-step plan to get there.
Dr. Treese emphasizes cooperation and shared decision-making rather than a one-sided interaction. Therapy blends psychological insight with behavioral steps.
This can mean trying new habits, adjusting thought patterns, or practicing different ways of relating to others. He also pays attention to attachment concerns, family-of-origin patterns, and feelings of emptiness or abandonment when those issues are relevant. Dr.
Treese uses a mix of approaches including existential ideas, acceptance and commitment strategies, and cognitive-behavioral tools to fit each person’s goals. He communicates by phone and messages in the morning and evening and aims to respond within 24 hours.

Online support
Approach-driven Online Therapy for Life’s Hard Questions
Dr. Treese integrates existential therapy, Acceptance and Commitment Therapy (ACT), and attachment-based ideas into online work. Existential therapy focuses on questions of meaning, choice, and facing life’s limits; it can help when someone feels empty, stuck, or adrift. ACT helps people notice difficult thoughts and feelings while committing to values-based action, which is useful for anxiety, depression, and habit change. Attachment-based approaches look at how early relationships shape current patterns, which can clarify communication problems, codependency, and intimacy struggles.Finding the right approach is part of the work. He will collaborate with each person to pick methods that match their goals, needs, and preferences. Sessions are conversational and goal-focused, with room to adjust methods over time based on what’s helping.
Online formats include video calls, phone sessions, live chat, and text-based messaging. Video is useful for in-depth conversations and visual cues, phone sessions are helpful when bandwidth is limited or people need a shorter check-in, live chat supports brief exchanges between sessions, and text messaging can assist with ongoing reminders or quick reflections. These options offer flexibility for fitting therapy into a busy life and for working with a therapist from Arizona even if the client is elsewhere.
