For the past 7 years I have worked with children and adults with special needs.  Over this time, I have worked for a private residential school for students with special needs, adult day and residential program, home service programs, and public schools. Over my time in the field I have developed a passion for parent/caregiver training and teaching functional living skills. Seeing a child or adult do something for the first time under a variety of conditions is the most rewarding thing to me.  I enjoy building relationships and improving the lives of the children and families I work with.

I have been working with students with disabilities for over 10 years and have been a BCBA since 2013. I received my Bachelor’s Degree with a dual major in Psychology and French from Clark University and my Master’s Degree in Education in ABA and Autism Studies from Endicott College. I have experience working with learners across a myriad of settings including a private ABA school, the public school setting and in homes. I am especially interested in working with the entire family to help find ways to increase parent education and sibling involvement, as well as working on social skills in a small group setting. When I am not at work, I am a busy mom of two little ones and we enjoy spending quality time outside with our dog. I look forward to getting to work with your family.

I received my Bachelor’s in Developmental Psychology from Plymouth State University and my Master’s in Education from Southern New Hampshire University. I have been in the field of ABA for 8 years now, and have a wide range of experience. I am trained in Acceptance and Commitment Therapy, and try to bring ACT not only into my life, but everyone around me as well! Outside of ABA, I have a lot of passions-from yoga to board gaming. I especially enjoy being outside with a good book after hiking or out on a boat on Winnipesaukee.

Functional communication is my favorite domain to teach! I currently work full-time at a public school and I am further my experience within the home setting at B.E.S.T.  Outside of ABA, I enjoy reading, watching Netflix, puzzles and biking and hiking during the warmer months with my husband.
