Parent Rating Average
After starting off rough in kindergarten, partly my child's immaturity, partly an inexperienced, impatient teacher, I couldn't be happier with this school. I was able to have as much face to face with the principal as I could possible want. Not to mention the principal is AMAZING! She is so friendly and easy going, plus has the knowledge to back it up. I am able to volunteer in my child's classroom this year and am blown away every time at how fantastic his teacher (and all the other staff and volunteers I have met) is! She mixes learning with fun and has that special ability to get the kids interested and keep them working. I am so happy with Wilson and am happy it is where my child ended up. Looking forward to more great years there!
