Over 30 Years of Counseling Experience

I’ve served in a variety of clinical roles for over 30 years, working with a wide range of clients across diverse settings. My career has included crisis counseling centers, psychiatric facilities, social service agencies, court-ordered programs, college counseling centers, and private practice. I’ve worked with individuals, couples, families, and groups across the lifespan. That breadth of clinical experience, across populations, presenting problems, and practice contexts, shapes how I approach every client I work with.

Today, my practice is focused primarily on two areas: adult ADHD evaluation and treatment, and couples counseling. I hold the ADHD-Certified Clinical Services Provider (ADHD-CCSP) credential, which reflects specialized training in how ADHD actually presents in adults, how to assess it accurately, and what the research says about treating it well. It’s a distinction that matters more than it might sound, because ADHD is one of the most frequently misdiagnosed and undertreated conditions in adult mental health.

My Work with Adults with ADHD

My approach to ADHD is research-based, solution-focused, and aimed at long-term change. I work with adults who are exploring what may be symptoms of ADHD, long-diagnosed but still struggling, or who have been told for years that their difficulties are something else entirely. I also work with adults who suspect they have ADHD but have never had a proper evaluation.

As many experts in the field of ADHD assert, ADHD is not a disorder of knowing what to do. It’s a disorder of doing what you know. That distinction shapes everything about how I work. The goal isn’t to help you understand yourself better in the abstract. It’s to help you understand the very real ways in which your brain functions as well as learning how to build the external systems, practical skills, and accountability structures that let you function well in your actual life, with your actual job, your actual relationships, and your actual brain…so you can stop asking WHY CAN’T I JUST DO IT!

A significant part of that work involves getting the diagnosis right in the first place. There is no single test that diagnoses ADHD. A proper evaluation draws on a detailed personal and developmental history, objective assessment data, self-report measures, and when useful, input from someone who knows you well. It also rules out, or rules in, the conditions that frequently travel alongside ADHD, including anxiety, depression, and mood disorders, which can look remarkably similar on the surface and require their own attention.

I work with adults across Arizona online and in-person in Flagstaff.

Couples and Relationship Work

Alongside my ADHD work, I continue to see couples regularly. I hold extensive training in Emotionally Focused Therapy (EFT), one of the most well-researched approaches to couples counseling available. I’m recognized as an expert in this area and have trained other therapists in EFT techniques throughout my career.

A number of the couples I work with are navigating ADHD in their relationship, whether one partner has a diagnosis, suspects they do, or has never considered it. I’m well positioned to work with those situations given my expertise in both areas.

Training and Workshop Leadership

Beyond therapy, I also conduct enrichment retreats and workshops on various topics. Most frequently, however, I train therapists on counselor ethics and Emotionally Focused Couples Therapy techniques.

Academic Excellence and Clinical Supervision

In addition to my private practice, I serve as Professor Emeritus in the Master of Science in Counseling program at Prescott College. Previously, I held roles as Director of Practicum and Internships and Associate Dean for Counselor Education. I continue to enjoy teaching and serve as an adjunct professor for Northern Arizona University and Prescott College.

As a supervisor approved by the Arizona Board of Behavioral Health Examiners, I provide clinical supervision, helping professional counselors and marriage and family therapists meet their licensure requirements for state licensure.

Board Positions:

  • Former Arizona Center for Emotionally Focused Therapy Board Member and Academic Programs Liaison
  • Former Arizona Counselors Association and Arizona Association for Marriage and Family Therapy board member

Presidential Roles:

  • Past-President of the Granite Mountain Psychological Society
  • Former President of the Wyoming Association for Marriage and Family Therapy

Additionally, I have served on the Arizona Board of Behavioral Health Examiner’s Marriage and Family Therapy Academic Review Committee for over 10 years.

I also served as Federal Advocacy Liaison, lobbying the Wyoming state legislature in Washington D.C. In this role, I advocated for local Marriage and Family Therapists. As a result, I understand both clinical practice and policy advocacy.

Personal Foundation

Most importantly, my wife and I have raised two daughters together. We’ve maintained a loving relationship for over 30 years, giving me personal insight into what makes relationships thrive. Consequently, when clients ask about overcoming relationship anxiety, healing from emotional wounds, or strengthening emotional connection, I draw from both professional expertise and personal experience.
