I went and trained w/ Renny Doyle of ATTENTION TO DETAILS.
I would highly recommend this training. He was really great to work with and a great guy in general. He definitely went above and beyond to make sure I got all the training I needed. They have many different packages that vary in time and subject matter so you can concentrate on exactly what you need from RV's to Airplanes. Previous to going you get a questionnaire asking about what if any experience you have and what are your main goals in training. This really helps almost "customize" your training. His wife Diane was great to work with and got me a great room rate at the hotel as well.
Also, Renny offers a lot of business related training in addition to "hands-on" training. Stuff like marketing and other things that will make your business successful. This area was really helpful to me.
The training was 1 on 1 so it really was intensive. I know they also have a program where you "share" w/ another person, so it's 2 on 1 . but pricing is about 1/2 and you still have a personal touch. I surely benefited more than I would have in a "class" setting!
I was really pleased with my investment. I am now a much better detailer, a much faster detailer, and a more confident detailer. Renny was awesome to work with and keeps contact with his students and will help you any way he can, even long after your training is done. I really hope to return for another training in the future. I could not give a higher rating to ATTENTION TO DETAILS training program.
