My work consists primarily of individual psychotherapy with adults and adolescents as well as marital and family therapy.
I have expertise in treating a wide variety of psychological issues, including conditions such as depression; anxiety and panic disorders; post-traumatic stress disorder and other conditions related to trauma or abuse; eating disorders; substance abuse and other forms of addiction; issues related to grief and loss; stress and anger management; and issues related to life transitions. My work with couples and families also addresses a variety of relationship issues.
In addition to psychotherapy, I have much experience providing supervision to other therapists in individual or group settings.
