In what ways does your personality influence your approach to therapy?

I haven an easy-going nature. This helps as it keeps me from feeling offended by things that people say and keeps me from trying to push my views on people.

How does collaboration with other providers play into your work?

Over the last 15 years I have had the opportunity to collaborate with many different providers. It has helped to shape how I view different diagnoses. I have worked with medical doctors, psychiatrist, psychiatric nurse practitioners, physical therapists and nurses. It helps to understand that the whole body needs to be treated, not just the mind/emotions.

What would be important for someone to know about working with you?

I do use humor. It has gotten me into trouble at times, and I do try to curb it. I do believe that humor does help relieve stress.
