I have been working at Roundhouse part time in the evenings for 2 years.  My full time work is with the Department of Defense and Navy Family Advocacy program. I have extensive experience working with individual adults, teens, couples and families. Prior to my work with the Navy I worked with adolescents and their families at a therapeutic boarding school.

I received my master’s degree in Social Work from Columbia University in New York City, and completed internships at the Educational Alliance that included working with at risk teens dealing with substance abuse and gang related issues, and working at the New York Association for New Americans, a refugee resettlement agency. Following my Master’s program, I spent 2 years in Botswana as a Peace Corp volunteer with the HIV/AIDS program working with orphans, vulnerable children and home based care patients.

I focus on a client-centered, strengths based approach that includes components of CBT, DBT and solution focused counseling. I specialize in working with individuals suffering from anxiety, depression and work related stress. I also work on developing healthy communication between couples and families to increase positive relationships. I promote self-care and positive self-regard and I like to incorporate aspects of mindfulness and yoga in to my practice.

Our Name

Why is our name Roundhouse?

We moved into our first office building in Old Town, Alexandria located on a site where once existed a railroad roundhouse. That’s how we got our name, Roundhouse Square Counseling Center. We moved across the street, but kept our name. The railroad metaphor inspired our tag line: “Getting you back on the right track.”
