Our Mission

We understand how difficult it is to find qualified, knowledgeable, and respected individuals to train instrument/bow makers and restorers. Until now, there were no schools in the United States that focused on these specific skills. It is critically important to impart years of experience, knowledge, and skills to the next generation so that musicians have qualified craftsmen and women to keep their instruments and bows in optimal condition.

In 2013, Mohr and Mohr began to offer small group and individualized training to prospective bow makers and restorers near and far. This is a trade difficult to learn and requires constant training. After having reached full capacity since its inception, Mohr & Mohr realized it was time to open a year-round training center focused on specific techniques in both instrument and bow making, as well as repair and restoration with a conservative approach. So, in February 2018, Rodney, Ann, and Katherine Mohr took the plunge and opened Learning Trade Secrets, LLC.  After experiencing a pandemic, COVID-19, in 2020 and having to cancel 14 of 16 workshops, the Mohr's decided to move Learning Trade Secrets back to their home studio.  The classes will no longer be held year-round, but rather April-August with a Bow Rendezvous at the end of September.

Knowing for centuries that makers kept many aspects of varnish and other techniques secret, the Mohr's decided to use the term in the name of the new company, hence 'Learning Trade Secrets.'  We hope you will come and learn the many Secrets of the highly acclaimed makers and restorers of the 21st century and centuries past. Instructors are invited from around the country to instruct you on the finer points of making and restoration of stringed instruments and bows, identification, business, and other important topics. 

Our Space

Our new workshop area accommodates up to 12 students in pods of 3, promoting student camaraderie. A centralized hook-up in each pod provides charging capabilities for cell phones, iPads, and other electronic devices. Rolling chairs with a height adjustment make it a breeze to adjust for optimal bench height for woodworking. A beautifully handcrafted cherry instructor’s bench, designed and built by Rodney D. Mohr, is the focal point for demonstrations.  A 75” television screen for compatibility with a computer, microscope, or simple movie watching adds to technology flexibility along with a 4’ x 8’ whiteboard ideal for class drawings and projection. 

The workshop is directly west of the current workshop and is within walking distance to downtown.  On the way North to downtown you'll pass the Post Office, Taco Bell, Rite Aid, the Ashland Library, the Chamber of Commerce and the Municipal Building, while next door is Romeo's Pizza and Dunkin Donuts. Across the street is Subway, Domino's Pizza, and Eva's Treats.  To the South is Ashland University, Burger King, Arby's, Pizza Hut, Little Caesar's, McDonald's, and several gas stations.  Needless to say, the location has a lot to offer as it is located on one of Ashland's main drags.  

We hope everyone will love the new location.  Expected moving date is September 5, 2023. Watch your workshop emails for the new address.
