Jeff Reaves

I have been an educator for 12 years throughout Volusia County. In 2013, I was named principal at Edgewater Public School. As principal, I led my school with a STEM focus (Science Technology Engineering and Math) and was the first elementary school in Florida to be certified by Advanc-ED in STEM. Adding Agriscience, Introduction to Computers, robotics and 3-D printing for career experiences in elementary, I was recognized as Florida’s Innovative Principal of the Year for 2017.

I also served as the principal at Holly Hill K-8 School. At both Edgewater and Holly Hill, students made gains in FSA scores, industry certifications as well as state EOC exams. This was accomplished while serving diverse populations and ensuring that all students were provided opportunities to be challenged and grow. I believe that we serve students best when we provide diverse educational paths to be college and career ready.

My undergraduate degree was earned from Warner Southern College in Organizational Management with post graduate degrees from Liberty University and Nova Southeastern University. 

I have three sons, three amazing daughter-in-laws and two beautiful granddaughters who light up my life.  Every day is a blessing to me that I have the opportunity to get up each day and work with wonderful students and staff.
