About Douglas
Dr. Douglas Treese is a psychologist with a PhD in Counseling Psychology and more than three decades of clinical work. He practices in Arizona and focuses on helping adults who are struggling with depression, anxiety, stress, grief, addiction, relationship concerns, and life transitions.
He uses clear, practical talk to map problems and plan next steps. He begins by listening to what matters most and identifying the patterns that keep problems going.
Background and approach
From there he and the client set concrete goals and pick strategies that fit the person’s life. Sessions emphasize collaboration - the client’s experience guides the choices made in treatment. Dr.
Treese draws on Emotionally-Focused Therapy to understand emotional patterns and attachment-based work to trace how early relationships shape current reactions. He also uses Acceptance and Commitment Therapy and Cognitive Behavioral Therapy when those approaches fit a client’s goals. Over his 36 years in clinical settings, he has worked in psychiatric hospitals, managed care agencies, and independent practice.
That range has shaped a steady, problem-solving approach to common concerns like midlife adjustment, grief, and addiction recovery. Practical steps are central to his work. He and the client identify specific behavioral changes, plan how to try them, and troubleshoot obstacles together.
The aim is lasting change that feels achievable in daily life.

Online support
How emotion-focused and behavioral approaches work online
Emotionally-Focused Therapy (EFT) focuses on identifying and reshaping emotional patterns that drive relationship and personal difficulties. It helps people notice what emotions are active, understand their meaning, and try new ways of responding to strong feelings. Acceptance and Commitment Therapy (ACT) teaches skills for accepting difficult thoughts and feelings while taking concrete steps toward values-based goals. It is useful for anxiety, depression, and stress when avoidance keeps someone stuck. Attachment-Based Therapy looks at how early bonds influence current reactions to closeness and conflict. It helps people trace patterns that show up in how they relate to others and learn new ways of connecting. Choosing the best approach is part of the work. The therapist will talk with the client about their goals, preferences, and what has helped or not helped before. Together they decide which methods to try and adjust the plan as progress is made. Online therapy makes this collaboration more flexible. Video calls allow face-to-face conversation to read emotion and tone. Phone sessions work well when lower bandwidth or stepping away from the screen is needed. Live chat and text messaging offer brief check-ins, homework support, and a way to maintain contact between sessions. These options help fit therapy into busy days and different schedules.We will earn a commission if you sign up through our link, at no cost to you.
