Meet Our Staff

Alexa Harrington M.A., BCBA

Alexa attended Stockton University where she received her BA in psychology and Georgian Court University where she received her Masters in ABA. Her career started at Search Day Program, a private school specifically for kids with autism, where she spent 4 years as a paraprofessional. She also provided direct therapy after school through a private ABA agency.

She transitioned to providing in-home services full time in 2018 and became a BCBA in 2019 after passing her exam - continuing to provide in-home therapy. She also has been a coach at Autism Movement Project (AMP), a fitness group for kids and adults with developmental disabilities, for the past three and a half years.

Her absolute favorite part of her job is getting positive feedback from parents that their child has carried over a skill to the home and outside of session. She said, “Getting a text or an update the following session about the child carrying over a skill that has been targeted during sessions outside of the session, makes everything worth it.”

Alexa got into the field as her uncle was diagnosed with autism spectrum disorder at the age of five. He is now in his sixties working a job he's had for over 30 years. He's her favorite person and she's lucky enough to support him weekly!

Jennifer Pollard M. Ed., BCBA

Jennifer attended Rowan University where she received her BA in psychology with a specialization in child behavior services. She then received her Masters of Education from Pennsylvania State University in Special Education focusing in Applied Behavior Analysis.

Her career started as a paraprofessional in an ABA preschool program while simultaneously providing in-home ABA services as a Registered Behavior Technician. Jennifer then moved on to a center-based program as an instructor where she worked full time to accrue her hours towards her BCBA and expand her experience within the field.

Jennifer became a BCBA in 2018 after passing her exam and transitioned to providing in-home services as a BCBA full-time.

Her absolute favorite part of her job is connecting with the families, incorporating parents/caretakers/siblings within programming and helping them reach their family goals as a team. Jennifer is always looking for opportunities to help educate her community (i.e., local law enforcement) about autism and ABA as a whole.

Sarah Smith,
Clinician’s Assistant

Sarah attended Rutgers University where she received her B.A. in Psychology with a minor in Education. She is currently attending FIT earning her Masters Degree in Behavior Analysis.

Before joining Shape to Success, she ran Buddy Ball, a special needs athletic league, for four years. She helped organize the baseball and basketball programs. This entailed recruiting qualified volunteers to help the children dribble, shoot, hit, field, and throw. The volunteers modeled the game for the children, building special bonds with their “buddies”, and made the sports meaningful, educational, and fun for the players. She worked closely with Special Education teachers in the local school systems to facilitate these programs.

Her favorite part of her job is seeing clients succeed in reaching goals and milestones in their life.

Apart from work, she loves to be on the beach with her family and friends.

Before this, he had spent three years working under different BCBA's using ABA interventions for companies such as: Golden Care Therapy, Caring Family Community Services, Heart to Heart Home Care and Kimberly Bohichik MA BCBA LLC. During this time, he primarily worked with children and adults on the autism spectrum, specifically in home settings.

His favorite part of working for Shape to Success is, “Working with the clients and experiencing first-hand the transformative work we do. Seeing them change and grow in a positive way because of the time, work and effort our amazing staff puts into the individual we care for.”

Outside of work, you can find Jacob on most weeknights or weekends at his local skatepark because he loves to rollerblade.
