I began my studies in psychology in 1996 and graduated with a Bachelor of Psychology in 1999. I also attained a Master of Arts Degree in Clinical Mental Health Counseling. Currently, I am a Licensed Mental Health Counselor in the State of Florida since 2017. My twenty years of experience with co-occurring disorders (mental health and substance use) have occurred in two states, Massachusetts and more recently in the last thirteen years in Florida. These have included individual/group counseling/therapy, case management, and in-home /school supportive counseling services. Most of my experiences are with the adolescent and adult population and I consider myself a person-centered therapist which to me means the following: Meeting a client where they are, upholding empathy (putting myself in someone else’s shoes), and remaining non-judgmental. In addition to maintaining a person-centered approach to counseling, I also believe and have learned in my past and current employment experiences the value of incorporating evidence-based therapies such as cognitive behavioral and/or solution focused approaches. Lastly, I incorporate a strengths-based approach within an individual coming to counseling. We will work as a collaborative team utilizing your expertise in your own life and what I have attained along my professional and personal experiences as they apply to your individual situation. The overall purpose of therapy is to work together towards your goals to achieve/attain an improved present and future life.
