Dr. Douglas Treese , AZ Psychologist PSY-001646

Dr. Douglas Treese is an Arizona-based psychologist who earned a PhD in Counseling Psychology in 1988 and is licensed in Arizona as AZ Psychologist PSY-001646. With 36 years of clinical experience, his work has spanned psychiatric hospitals, managed care agencies, and private practice, giving him a broad perspective on adult mental health care.

He works with adults both individually and in marriage and relationship counseling. Over the years his clients have presented with depression, anxiety, interpersonal difficulties, stress, mid- and later-life adjustment, grief, life-plan development, and self-esteem concerns. His clinical background supports practical work on these issues while attending to each person’s unique circumstances.

Dr. Treese frames counseling as a collaborative process on a level playing field, where participants exchange ideas and discover solutions together. He begins by mapping what is causing the problem or identifying areas the client wishes to enhance. From that foundation he examines the psychological and behavioral changes indicated and considers how those changes can be achieved.

He emphasizes that making and sustaining change is difficult to do alone, and he focuses on strategies to establish and maintain progress. Prospective clients are invited to request an appointment. He checks messages in the morning and evening and responds within 24 hours.

Integrating Therapeutic Approaches for Online Support

Dr. Treese draws on Acceptance and Commitment Therapy and Attachment-Based Therapy to guide his online work. Acceptance and Commitment Therapy (ACT) helps clients clarify personal values and take committed action even when difficult thoughts and feelings are present - it is useful for anxiety, stress, and life transitions. Attachment-Based Therapy focuses on patterns of relating and emotional bonds formed in close relationships; it can be helpful for addressing relationship difficulties, abandonment concerns, and attachment issues.

Finding the right therapeutic approach is part of the collaborative process. Dr. Treese and each client work together to determine which methods best match the client’s needs, goals, and preferences, and adjustments are made as therapy progresses so the plan remains responsive and practical.

Online sessions are offered through video calls, phone conversations, live chat, or text-based messaging to increase flexibility and access. These options allow clients to fit therapy into busy schedules, attend from different locations including international settings, and choose the communication style that feels most comfortable. Licensed professionals and therapists can adapt these formats to support ongoing progress and practical problem solving.
