I've never been to Skyline pool but my kids have taken lessons at other pools in Mesa & they were great. Maybe try a differnt pool.
We do not live in Mesa anymore so have transfered our kids to Evo Swim School, their main pool is in Gilbert but they do have lessons in Queen Creek & north Mesa. They are excellent! My 3 year old daughter is swimming all on her own, can front & back float & swim almost the length of our backyard pool by herself. All the instructors are patient with kids that cry or are shy. They are worth the money! Check them out if you get time.
