    I am a licensed Marriage and Family therapist in Pennsylvania and is currently working towards certification as a Sex Therapist. I received her Master’s in Marriage and Family Therapy and a second Master’s degree in Human Sexuality Studies with a concentration in Sex Therapy from Widener University. I have several years experience in relationship counseling, Family Therapy and Outpatient individual therapy with clients of diverse backgrounds, age ranges and presenting concerns, including; family, couple, individual, relational and sex therapy.

    I know therapy can be uncomfortable and I use a collaborative, strength-based and trauma informed approach to treatment to create an open and supportive environment. I operate from an intergenerational and interpersonal approach, highlighting how various relationships shape your identity, experience and behavior. My goal is to support clients in feeling comfortable, heard and empowered to make changes in their lives. I use various systemic modalities of therapy, including Gottman therapy, sex therapy techniques and family therapy interventions. I enjoy humor as a therapeutic tool and to connect with my clients.

    Stacie is certified as an AAMFT Approved Supervisor to provide counselor supervision towards licensure as a Marriage and Family Therapist, LPC or LCSW and is accepting graduate students and prelicensed therapists for supervision towards licensure.

    In my free time, I enjoy spending time with her family, including pets, traveling and boating.
