Gerald Matthews, MD

James "Derek" Slover, LPC-S (but just call him Derek), has been practicing counseling since 2006. He has worked in a wide range of settings, including community clinics, hospitals, and telehealth- and now helps teens, parents, and adults navigate the challenges of anxiety, mood disorders, behavior issues, and more.

Derek's approach is collaborative, practical, and rooted in evidence-based care. He brings humor, clarity, and a no-nonsense style to counseling, believing that treatment should make sense and feel useful. You won't get psychobabble or a 47-slide PowerPoint presentation- just honest conversations, thoughtful listening, and tools that work. His clinical toolbox includes CBT, Parent Management Training, Exposure & Response Prevention, and other proven approaches tailored to each person's needs.

Counseling with Derek starts with a thorough assessment to understand what’s been getting in your way. From there, you’ll work together to set goals that reflect your values and priorities. Counseling typically moves through three phases: 1) building a strong therapeutic relationship, 2) doing the deep work of change, and 3) maintaining progress and preparing for graduation- because counseling should be a launchpad, not a lifelong subscription.
