About

COVID-19 and 2022

Thank you for considering one of our workshops during such uncertain times.  As we say, "Expect the unexpected, and you'll be fine."  Due to COVID-19, its varieat, and other viruses, we understand that things change at the drop of a hat, therefore, we understand if you have registered for a course and find that you must cancel your plans.  Should you find that you and/or a family member has become ill, please stay home.  We will refund your tuition up to 2 weeks prior to the workshop or save your payment for a later date.  If you have an opportunity to receive a vaccine we hope you will do so. 

And although things are somewhat normal again, Airbnbs may be limited.  For your safety and wellbeing, we suggest you consider a hotel. However, we have it on good authority that an Airbnb on Center Street in Ashland may be opening in the near future. 

We hope you will consider attending a workshop in 2022.  Look for registration availability in late October.

Our Mission

We understand how difficult it is to find qualified, knowledgeable, and respected individuals to train 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, and 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 to their home studio.  The classes will no longer be held year-round, but rather May-August with a Bow Rendezvous 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 workshop area accommodates up to 9 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 makes 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 walking distance to downtown for shopping and local eateries. The courtyard between the 1885 Queen Anne home and the workshop is a beautiful setting for outdoor picnics and enjoying the fresh outdoors.
