Comprehensive psychological evaluations for ADHD, autism, learning differences, and complex diagnostic questions, with a written report that's readable and a feedback session that makes sense of the results. Psychotherapy also available for adults.
You've been wondering long enough.
A psychological evaluation gives people something to stand on — a clear picture, a framework for self-understanding, and language for what they’ve been experiencing. The therapy I offer comes from the same orientation: collaborative, focused, and thoughtful work on understanding what's behind the symptoms.
For people with longstanding questions about attention, focus, organization, or follow-through.

Not advice. Not a script. Just careful attention to what's going on and what's behind it.
You've wondered about ADHD, autism, or learning differences for years but never pursued a formal evaluation, or the one you had didn't give you a clear answer.
You've been dismissed, misdiagnosed, or told your symptoms aren't significant enough. Something still doesn't add up.
You're seeking accommodations at work or school, need a formal diagnostic picture to share with providers, or want documentation that reflects what's actually been going on.
You have overlapping presentations, a complex history, or prior evaluations that raised more questions than they answered.
Dr. McKenzie is a licensed psychologist in Arizona with doctoral training in psychological assessment and psychotherapy. He completed his doctoral training at Antioch University New England, his APA-accredited internship through the Southern Arizona Psychology Internship Center (SAPIC), and his postdoctoral fellowship in psychological assessment and psychotherapy.
The work is thorough and multi-method, but what matters most is what comes after the testing: a report that actually explains something, and a feedback session where the findings become useful. Psychotherapy is also offered for adults who want to understand what's driving their symptoms, not just manage them. Collaborative, focused work on patterns and what's behind them.
