My passion for my own four children, as well as those who continue to attend here, has been to do all I can to help them grow physically, academically, emotionally and spiritually to be all they can be in Christ. My varied background including a B.A. from East Stroudsburg State University, PA, along with great dance and performance experience gleaned from years of living in the NY metropolitan area, have enabled me to serve in a variety of roles at the school. The shared focus of staff and teachers alike, to support one another, while wholeheartedly serving the Lord, our families and students are unmatched by anything I have encountered.
