I grew up in the small, rural town of Woodstown, NJ. While there, I attended Rowan University where I earned my Bachelor of Science Degree in Civil Engineering with a Minor in Mathematics. Immediately following graduation, I continued my studies at Rowan and earned my Master of Science in Teaching Degree for K-12 Mathematics.   

My wife and I reside in Hinsdale, NY, and have been married since the fall of 2011. We have been members of our church's worship team since 2011 and became the worship leaders during the summer of 2019. We have a cat, 2 chinchillas, and a beautiful daughter born in September of 2018. We are expecting our second child in April of 2021! 

From September 2011 to June 2018 I taught primarily 8th grade Physics and 9-12 Math at Archbishop Walsh Academy, a small, private school located in Olean, NY. While there, I also started a fall cross country team, spring track team, and played the piano for various school events including the winter and spring concerts, musicals, and Solofest. I also taught a Statistics class for one semester at St. Bonaventure University and interned for the Town of Ellicottville Highway Department in the summers of 2016 and 2017. 

As an employee of Cattaraugus-Allegany BOCES, I work for Pioneer School District 60% of the time as a Math/Science Curriculum Coordinator focusing on grades 5-12. My office is located at Pioneer Middle School in the Curriculum Office. 

Even when not in district, I am always available so please don't hesitate to reach out! My ultimate goal is to continue helping each of our students be successful in any way I can!

I was raised in East Aurora, NY and graduated from East Aurora High School in 1977. For my undergraduate studies I attended Duke University for two years, and then transferred to St. Lawrence University, where I earned my Bachelor's Degree. I earned my teaching certificate after attending Canisius College, and then earned my Master's Degree in Educational Change and Technology Innovations from Walden University's online degree program, with a residency stay at the University of Indiana. (As you can see, I've participated in quite a few university programs.)

Along the way to my teaching career I've worked as a professional actor and scenic carpenter, a home builder, a feed mill laborer, a dump truck driver, and a radio advertising salesman.

I began my career at Pioneer as a 7th grade Math teacher, but soon moved to my current position as the district's K-12 Technology Integrator, a position I've held for the past 25 years.
