People come to therapy for all kinds of reasons — sometimes a specific event, sometimes a slow accumulation of things that no longer feel workable, sometimes a sense that something important has shifted and they're not sure how to find their footing again. Whatever brings someone in, Trey's approach begins in the same place: genuine curiosity about who this person is and what their life actually requires.
Trey is a licensed clinical psychologist, board-certified by the American Board of Professional Psychology (ABPP), with nearly 20 years of clinical experience across a broad range of settings and presentations. He has worked in the U.S. Army, correctional systems, hospice, university counseling centers, and inpatient/outpatient hospital contexts before establishing Quandary Peak Counseling — a background that means he has sat with people in some of the most difficult circumstances human beings encounter. That experience informs a clinical style that is direct without being cold, intellectually serious without losing sight of the person, and grounded in the belief that real change is possible even in longstanding or complex presentations.
He was primarily trained in an existential and humanistic framework; however, he additionally draws on psychodynamic, relational, and other evidence-based frameworks (CBT, ACT, etc.). In practice, this means the approach is shaped by what each individual client actually needs — not a fixed protocol applied uniformly.
Areas of Focus
Trauma & PTSD
Trey works with survivors of a wide range of traumatic experiences — accidents, assault, medical trauma, occupational exposure, and chronic adverse experiences. He draws on evidence-based approaches including Cognitive Processing Therapy (CPT) and exposure-based methods, alongside deeper exploratory work when the clinical picture calls for it. He is recognized as an expert in traumatic stress by the American Board for Experts in Traumatic Stress.
Depression & Mood Disorders
From persistent low mood and loss of meaning to more acute or complex mood presentations — including bipolar spectrum disorders — Trey brings careful diagnostic thinking and a range of therapeutic approaches to depressive and mood-related concerns. He is particularly attuned to depression that has an existential or characterological dimension, where the question isn't just symptom relief but something more fundamental about how a person is living.
Personality & Relational Patterns
Some of the most entrenched suffering people carry isn't situational — it's embedded in long-standing ways of relating to themselves and others. Trey works with clients exploring personality-related concerns, interpersonal patterns that keep repeating, and the kind of relational difficulty that tends to show up across contexts. This work is often longer-term and depth-oriented.
Grief & Loss
Grief doesn't follow a schedule, and it isn't always recognized as grief by the person experiencing it. Trey works with clients navigating bereavement, anticipatory loss, complicated grief, and losses that don't fit conventional categories — including losses of identity, relationship, or meaning.
Existential Concerns
Questions of meaning, purpose, identity, and authenticity aren't peripheral to mental health — they're often at its center. Trey works with clients for whom the presenting concern is less about a diagnosable condition and more about a felt sense that something isn't right: a life that looks fine from the outside but feels hollow, a crisis of values, or a transition that has called everything into question.
Psychosis & Schizophrenia Spectrum
Trey has clinical experience with psychotic disorders and schizophrenia spectrum presentations, including both diagnostic evaluation and ongoing psychotherapeutic support. This is a population that is underserved in private practice settings, and he approaches this work with the same rigor and respect he brings to any clinical presentation.
