Autobiographical Information





          When I was in elementary school, I loved to pretend to be a teacher.  My best friend and I would play on a daily basis.  Her name was Mrs. Thompson and mine was Mrs. Fruit.  I believe I always knew I was going to be a teacher when I grew up!

           In middle school, I learned about a family who was looking for someone to volunteer to play with their little boy with autism on the weekends.  I signed up and was very eager to start.  Little did I know how difficult this opportunity and experience would be.    

     Jake was about 3 years old and had difficulty providing eye contact, attending, and had seizures daily.  I worked with Jake for about a year, but without training from the parents and being a child myself, I started to become disheartened.  I didn’t feel like I was helping him.  I was young and therefore didn’t know how to understand what I had been through, or what Jake was going through.  Even though my weekends with Jake ended, my curiosity didn’t.      

          In my junior year of high school, I started my teaching career at the Islip Technical Center.  I signed up for their two year program.  The first year, I learned teaching definitions and participated as an assistant teacher at their on site day care.  The second year, I was a student teacher at my old elementary school.  Student teaching as a high school student was very exciting and I looked forward to it every day.

         In my second year of college, I started to do my observation hour requirements.  I started my observations in special education at the Kramer Learning Center.  After doing some observation hours in a classroom, the school asked if I wanted a job during the summer as a 1:1 for a child with autism.  I was honored to receive this opportunity and fell in love that summer with his big beautiful brown eyes.  After that summer, my goal became to learn more about teaching children with autism and this goal led me on a wonderful journey.    

          In May 2005, I graduated from Saint Joseph’s College with my teaching degree.  (Areas of certification: Initial Early Childhood, B-2, Initial Childhood, 1-6, Students with Disabilities, B-2, and Students with Disabilities, 1-6).  

         Immediately upon graduating, I started working at Developmental Disabilities Institute.   I was the teacher of an EI classroom, and then a preschool classroom. I received priceless training while teaching there and I am grateful for the experiences I received.   

            In December 2007, I graduated from Long Island University with a Masters Degree in Special Education.  At this time, I thought I was done with school (woo-hoo), little did I know I had bigger plans for myself!

            In 2009 I started working with Achieve Beyond/Bilinguals Inc. as a Parent Trainer, SEIT, team leader and ABA home therapist.  I also founded a non-for-profit sports organization, Team Heroes Inc., for children with autism that year. 

           Team Heroes Inc. is an organization run by Special Education Teachers and other dedicated, loving volunteers.  It is run in an ABA type format and modified to fit children’s individual needs.  Parents interact and participate with their children on the field, while Special Education teachers and Volunteers facilitate the experience on the field. It is an integrated setting open to all children with autism and their siblings, between the ages of 3 and 9.  We work on teamwork, passing, eye contact, following directions, sharing, turn taking, waiting, socialization, learning the basic skills of the sport and most of all having fun!

          In September 2010, I received my B.C.S.E. (Board Certified Special Education) Certification and started to publish the I Love to Pretend Social Stories Series. 

         I Love to Pretend stories were created in order to teach children with autism how to pretend play.  There are three books in the series so far: Let’s Play Doctor, I’m a Daddy, and Let’s Play Cashier.

         In September 2012, I received my B.C.B.A. (Board Certified Behavior Analyst) certificate.  At that time, I was offered a job as Behavioral Consultant/Home Therapist/ Supervisor at Kidz Therapy LLC/GEK Resources.

         My experiences throughout my years of teaching include training in ABA, discrete trial teaching and natural teaching.  I have also received training in writing FBAs, BIPs, BSPs, IEP’s, as well as implementing strategies such as PECS, visual schedules, video modeling, token systems, and many other important strategies in which an ABA teacher should be knowledgeable.  

         I love to learn and I thrive from learning new ways to teach and make our world exciting to our students!
