I am originally from New York City and spent most of my childhood living in Mahopac, a suburb of the city. I received my Master’s degree in Counseling Education from Slippery Rock University in Pennsylvania in 1989. I started my career as a Counselor and worked in that capacity for the next 6 years working in several settings including an outpatient clinic, hospital and residential program. In 1995 I transitioned into administration where I have been since. I did maintain a small private practice from 1999 until 2014. During my experience as an administrator I have helped support and promote clinical programming with a focus on evidenced-based interventions and utilizing data analytics to help organizations become more efficient in their service delivery. I started an infant and early childhood program in 2006 with one staff and no clients and grew it to a staff of 50 serving over 950 children ages birth to 6 by 2014. I have introduced evidenced-based therapies into several organizations including Circle of Security, EMDR, Theraplay, Trauma Focused CBT, Parent Child Interactive Therapy and Child Parent Psychotherapy. I helped an agency bring in Applied Behavior Analysis and recruited BCBAs to oversee the program. I entered into the mental health field because I wanted to help people. It just seemed to be a natural fit for me. I still feel that I help people, I just do it from behind the scenes and support others who help the children and the families. That is my role here at S.E.E.K. Arizona. As the clinical director I help support supervisors, therapists, counselors and coaches so they can help the families we serve. As someone who has been doing this for a long time I really enjoy helping others grow and develop professionally. I feel blessed and humbled to be part of the S.E.E.K. family.
