Mike Culbreath

Master Electrician, Graphic Artist–Mike Holt Enterprises

Mike Culbreath has devoted his career to the electrical industry and worked his way up from apprentice electrician to master electrician. He began by doing residential and light commercial construction, and later did service work and custom electrical installations. While working as a journeyman electrician, he suffered a serious on-the-job knee injury. As part of his rehabilitation, Mike completed courses at Mike Holt Enterprises, and then passed the exam to receive his Master Electrician’s license. ln 1986, with a keen interest in continuing education for electricians, he joined the staff to update material and began illustrating Mike Holt’s textbooks and magazine articles.

Mike started with simple hand-drawn diagrams and cut-and-paste graphics. When frustrated by the limitations of that style of illustrating, he took a company computer home to learn how to operate some basic computer graphic software. Realizing that computer graphics offered a lot of flexibility for creating illustrations, Mike took every computer graphics class and seminar he could to help develop his skills. He’s worked as an illustrator and editor with the company for over 30 years and, as Mike Holt has proudly acknowledged, has helped to transform his words and visions into lifelike graphics.

0riginally from south Florida, Mike now lives in northern lower Michigan where he enjoys hiking, kayaking, photography, gardening, and cooking; but his real passion is his horses. He also loves spending time with his children Dawn and Mac and his grandchildren Jonah, Kieley, and Scarlet
