I wanted to write and thank you all for the hospitality and the class.  It was a great experience and I got a lot out of it.  I hope your endeavor meets with success.  I am certainly talking it up to the people I know.  It's a great space, and a well set-up and thought out program.  I would love to take another class...  So, good job!

The bow rehairing course was pretty amazing.  I've been to a ton of seminars and this was tops.  Such an enjoyable, pragmatic approach to working on bows.

Thank you all so much for such an amazing workshop!  I was truly blessed by it all.  I learned so much and had a lot of fun too.  I am inspired to work harder and grow more. I truly appreciate how you run the workshop.  All of the details make it so worthwhile.  But best of all it is such a pleasure to learn from you.

It has been a privilege to learn from Rodney Mohr.  Little did I know that my life would change after I attended his bow rehair class.  I wouldn't be where I am today without his guidance and expertise.

The Mohr's are phenomenal instructors!  Very well thought out course.

I loved their rehair and repair workshops. I came in without any tool skills and was still able to complete rehairs and several repairs. They worked with me until I understood each concept and it was exciting watching my work transform.

Great rehair workshop!  I by far outpaced my expectations. I couldn’t recommend this course enough for someone interested in starting into their first thousand bows!
