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 those who have ASD since 2014 and knew that I wanted to make a difference in children’s lives.  After receiving my bachelor’s degree from Salem State In 2018, I began my career at the May Institute and went on to receive a Master’s in Behavior Analysis and became a BCBA.  I have experience with individuals ages 5-22 teaching social, academic, daily living, communication, and vocational skills. 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.

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.

After receiving my bachelor’s degree from Worcester State in Communication Sciences and Disorders, I went to Cambridge College where I got my master’s in Applied Behavior Analysis concentrating in autism spectrum disorders. I’ve worked in public schools as a Speech and Language Assistant as well as private companies providing ABA services to clients ranging from pre-school to adults. Seeing clients gain independence is one of my favorite parts of teaching using behavior analysis. In my free time, I like to listen to true crime and dog training podcasts. I also love to play softball and stay active with my new puppy.

 I have a Bachelor of Science in Psychology from

Evangel University and a Master of Science in Behavior Analysis from Simmons University. For the past 17 years I have worked with children and families as a social worker. It is my passion to work to improve outcomes, build positive working relationships, and find joy in everyday things. I especially enjoy Natural Environment Teaching and using the child’s interests to teach relevant skills. Outside of ABA, I love to read, crochet, and playing The Legend of Zelda. It is always a pleasure to meet new families and I look forward to working with you!

I love working in this field and being part of a team of people that strive to positively impact the lives of families and the communities we serve everyday. I am a New England native interested in traveling the world and disseminating the field of applied behavior analysis to remote and in-need communities.

My passion is to further disseminate the Science of Behavior Analysis by making positive behavior change more accessible, as well as generate a meaningful impact in the community that I live and work in. I plan to do so by using the basic principles of the Science and applying them directly to my client’s needs. Ongoing data collection will be the means to drive programming and analyze the efficacy of the interventions. Outside of my work in public schools across Massachusetts, I enjoy practicing yoga, gardening, and going for hikes. I passed the board exam in 2016 after graduating with a Masters in Applied Behavior Analysis from Simmons University.

I received my BCBA and my Masters in Severe Special Education in 2011 from Endicott College. Prior to working for B.E.S.T, I spent six years at Melmark New England ,and then several more in the public schools as a teacher and a BCBA. Born and raised in Lynn, MA,
I now live in Ipswich and spend as much time as I can at Crane Beach. I am one of those crazy people who get up at 5 am to workout and it gives me the energy I need to keep up with all my
clients. I prefer to drive a standard over an automatic, and I am positive that SVU is the best in
the Law and Order Franchise.
