Looking for Respite worker

We have a 16 year old boy with cerebral palsy. He is very active and mobile. He enjoys hiking, biking, swimming and para-dressage. Currently, we are looking for assistance with keeping him active as the more active he is the more functional he is. This summer, we are looking for someone to who can take him out for activities 3 - 4 times a week. This can include going for bike rides in his adaptive bike, hiking the local trails like Mount Douglas. He does not have any mobility devices, but he require some assistance with getting his foot settled in his bike or walking over difficult terrain. He is a gregarious and fun loving teenager who also loves to kayak and play video games. We are flexible with hours and can work around other employment.
