I am proficient in assisting clients to navigate transitions in all aspects of the life span. Over the past 30 years, my experience has taught me that the most important aspect of therapy is the connection and comfort you feel with the person with whom you choose to share your personal struggles.

I like to listen to what patients are telling me about what is important to them and what they would like to address in therapy.  We can then start to set goals together and work towards the outcomes they want.  We always go at a pace that is comfortable to the client.
