My Training and Background

I have a Masters in Clinical Psychology and a Ph.D. in Clinical Child Psychology from DePaul University in Chicago. I received a certificate in Gestalt therapy from the Gestalt Institute of Cleveland.

I’ve presented and published on numerous topics including autism, anxiety, stress, parent-child communication, and aviation mental health.

Working with Miles

I’m familiar with the tenacity and courage it takes to enter therapy and make personal changes to overcome challenges. Therapy is a unique place where you can be nurtured and challenged. I look forward to getting to know you and walking with you to explore new possibilities together.
