After tiring of extensive travel, and with small children, Michael returned home to Oklahoma he continued working in the electrical trade. With his vast experience in the industrial and commercial aspect of the electrical field, he became an instructor.

Recognizing his passion for electrical education, he began teaching continuing education classes for EMSCO Electric Supply and I.E.C.

Mike Culbreath

Master Electrician, Graphic Illustrator, Mike Holt Enterprises, Inc. Alden, Michigan

Mike Culbreath devoted his career to the electrical industry and worked his way up from apprentice electrician to master electrician. He started in the electrical field 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. Becoming aware 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 computer graphic skills. He's now 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.

Mike loves spending time with his children Dawn and Mac and his grandchildren Jonah, Kieley, and Scarlet.

Electrical Inspector and Plans Examiner
Collier County, Florida

His experience included new multifamily building of 8 to 12 units, basic homes, a few light commercial jobs in between, and ending up in hi-end homes. He attended the local apprenticeship program and obtained his Journeyman’s license in April 1989. He procrastinated until 1996 and then obtained his Masters license. An opportunity to become an electrical inspector for the local jurisdiction January 10, 2000 presented itself and he obtained his Florida Inspectors license April 4, 2001 and his Electrical Plans Examiner license March 19, 2002. David has been working in the capacity of an electrical plans examiner since May 2005.

During his tenure with the local jurisdiction, he obtained his SBCCI (ICC) 1-2 Family Dwelling Inspector, Fire Safety Inspector I & II, and Fire Plans Examiner certifications. At present, he’s in his third and final year of cross training with BOAF for licensure as a Building Plans Examiner.
