Welcome to Deiss Psychotherapy. Let’s create your best life together.

Therapy doesn’t have to look one way. It can be inspired by the things you care about and filled with the stories that matter to you.

    So if you love Star Trek...

  • Campfire with flames and burning logs outdoors, with trees and mountains in the background. Text overlay reads: 'CAMPFIRES: BEST THERAPY EVER!'

    ... or the great outdoors...

  • ... or cooking...

  • A close-up of Gandalf the Gray's face on the left side and a quote on the right side reading, "All we have to decide is what to do with the privilege that is given to us." The word privilege has been overlaid on the word "time."

    ... or Lord of the Rings...

  • An elderly woman with white hair wearing large sunglasses and a shiny gold jacket, making a rock and roll hand gesture against an orange background. A speech bubble next to her reads: "ROCK ON!"

    ... or whatever your thing is!

Hi, I’m Dr. Felix Deiss and I’d love to work with you!
