I’m Thomas Moore, LPCC, a licensed professional clinical counselor providing therapy for individuals navigating anxiety, trauma, emotional overwhelm, identity development, and complex relational patterns. Many of the people I work with feel stuck in repeating cycles such as overthinking, people pleasing, emotional shutdown, intense reactions, or difficulty maintaining stable relationships even when they logically understand what they should do. My goal is to help you translate insight into real change.

My approach is structured and compassionate. I integrate evidence based methods including cognitive restructuring, emotional regulation training, interpersonal effectiveness skills, and trauma informed therapy. Sessions focus on understanding why your brain reacts the way it does and building practical tools you can actually use outside the therapy room. This is not only about talking through problems but learning how to respond differently when they show up in real life.

I work well with clients who want more than passive support and are ready to build skills, increase self awareness, and interrupt patterns that no longer serve them.

What clients should know before starting

Therapy with me is collaborative and active and you will learn strategies rather than only venting. We will work on understanding both the emotional and neurological side of your reactions. Sessions focus on present day functioning while also addressing past experiences that still affect you. I may gently challenge patterns when it supports growth while maintaining a supportive and respectful space. Progress often comes from small repeated changes rather than sudden breakthroughs.

If you are looking for therapy that combines validation with practical change, we will likely work well together.

Clients should have appropriate acuity in the mild-to-moderate range for telehealth care. Certain conditions or symptom severity levels may need a more intensive care setting than telehealth. Same week appointments available.
