Blake Waeger

I started tinkering with old cars when I was 13 and enjoyed the challenge of learning how things work. I started changing oil at a lube shop while going to tech school my senior year of high school. I was very fortunate to be accepted into the Jackie Cooper family the day I graduated high school in May of 2000. I started working on Porsche vehicles in 2003 and have thoroughly enjoyed the brand since day one. When I  am not working I enjoy motorcycling and hunting.
