Clinical Supervisor

Since 2012 I have worked with children and adults with a variety of abilities and disabilities.  I have a passion for providing care and training in the home and in the community where children spend the majority of their lives.  Over my time in the field I have most enjoyed building relationships, seeing children and families develop new skills and improve their lives together.

I began my career in ABA in 2008 and graduated with my Masters in Applied Behavior Analysis in 2012 from Westfield State University.  I was the clinical director of the May Center School for Autism and Developmental Disabilities in West Springfield and I have participated in a wide variety of services related to those with special needs. I have a passion for services that provide individuals with quality of life through leisure and recreation. When I am not practicing ABA I enjoy whittling and woodworking, playing volleyball, and enjoying the great outdoors.

I have always loved teaching, first as a Karate Instructor, then as an English teacher in South Korea, and now as a BCBA! I received my bachelor's from UMass Lowell with concentrations in Psychology and English and later got my Master's from Arizona State in Special Education with an ABA concentration. I love helping clients find new and different ways to express themselves and their needs. In my free time I love spending time with my family, playing card and video games, and going for very long walks with my family's dog.

I found my love for ABA a Behavior Technician while I was in graduate school for Clinical Psychology in 2008.  Watching children grow and supporting their families became my passion and I went on to become a BCBA in 2014.  My experience spans across multiple settings, social skills groups, and parent consultation ages 18 months to 50 years of age. I find my joy in working with families and individuals to improve their quality of life, independence, and access to meaningful skills and activities.

I found my passion for ABA as an RBT in 2019 which led me to pursue my career as a BCBA.  I am deeply committed to providing compassionate care that empowers my clients to thrive. My practice is rooted in an assent-based approach, ensuring that every individual I work with feels respected and heard. I believe that true progress comes from building trusting relationships and honoring the needs and autonomy of each client. Outside of work, you may find me karaoking, painting, or spending time with my crazy family!
