Hi- I just completed my skydive today with Chris. I wanted to give him and the other instructors a compliment on how professional they were and what a great job they did at making me feel at ease about jumping out of a plane at 14,000 feet! I felt like I was in completely capable hands and after getting home and watching the video I am so impressed on how he was able to take video at the same time. I would highly recommend Chris or Skydive Philadelphia to anyone looking to take a skydive. Thanks for the adventure! -Sarah
