Board of Directors

Board of Directors

OCA's Board of Directors works tirelessly to ensure the mission of Oasis Christian Academy. As an independent entity unaffiliated with any specific ministries, our Board of Directors is a vital component of the academy. They bring a diverse and varied insight, as the Lord has called them from different walks of life.  While board members are volunteers, they are intrinsically involved in overseeing and confirming best practices throughout OCA.  

Our mission is to preserve our history, clearly defining where we came from and following God’s plan for the Academy’s future. We will seek God's plan for the future of Oasis Christian Academy by continually being in prayer, reading and studying His Word, and listening to Him.  We believe in being committed to excellence in education by maximizing available resources and understanding our proper role in overseeing Oasis Christian Academy with openness and integrity.  We are committed to the Oasis family we serve by providing guidance, support, and encouragement to all stakeholders, striving to honor God with each interaction, and working for the individuals, families, and school as a whole. 

"Without consultation, plans are frustrated, But with many counselors they succeed."- Proverbs 15:22 (NASB)

Lynn Polston is originally from Connecticut.  She relocated to the Winter Haven area when she was 18.  She has been married to her husband David for 16 years and has the privilege of raising their granddaughter, who attends Oasis.  She has been the owner of an Insurance Agency since 2017, and prior to that, she was a Licensed banker.

Lynn loves this school and wants to see it succeed and grow for many more years to come.  Lynn believes It gives kids a great place to learn and develop into successful young men and women with a strong Christian foundation that will help them through life.
