Chris Carrion-Alfano

Owner and Assistant Center Director
Chris is the co-owner and Assistant Center Director at Mathnasium of Sayville. In June 2019, she retired from the Middle Country Central School District after 34 years classroom experience working with students in grades K-7 as a Special Education Teacher. Chris has been recognized by the district, her peers, and her students’ parents for her unique, highly effective teaching style, team leadership skills, and unwavering dedication to working with and helping challenging students. In 2019, she was selected by the NY State Board of Regents as one of two finalists for the Helen Bach Moss Memorial Better Beginnings Award, which “recognizes elementary teachers who are gifted in finding and nurturing the strengths of each student and fostering trusting relationships among pupils, parents, teachers, and administrators.” She was selected by her district's special education department leadership team to leverage her knowledge and experience to facilitate monthly meetings as the Parent Trainer and Counselor for parents of special needs students. She self-published Animals Can Demonstrate Values Too—a character education book used by teachers as a springboard for discussion alongside school district character education curriculums. Chris holds a Master of Science in Education from Adelphi University (with 90 educational field credits post-Master degree), and a Bachelor of Arts in Education from Dowling College. Chris is excited about expanding her reach by working with her husband, Rich, to help students in the Sayville, Oakdale, and surrounding communities develop their number sense and gain competence and confidence in their math skills. Chris is known for inspiring self-confidence and a can-do attitude in her “Cool Cats,” and brings this same energy to Mathnasium of Sayville, where she works with our youngest students and students with special needs, and coaches and trains our staff!
