Dennis M McCoy & Sons, Inc. was founded and began operating in its current iteration in 1994 by Dennis M McCoy in Westlake Village, CA. Beginning his career in construction in the late 1960's, while working as a teenager for his father's Southern California-based construction company, Mr. McCoy developed his skills. Under the watchful eye of his father Lester C McCoy, he learned the fundamentals during summer breaks and weekends. This continued until the late 1970's.

Over the next 20 years, Mr. McCoy introduced his three sons to the heavy construction and general contracting business while projects including mass grading for the purpose of large-scale commercial and residential development were underway. In the mid-1990's Dennis M McCoy & Sons, Inc. were awarded their first Reclamation contract in the state of Wyoming. During this time, Mr. McCoy saw his 2 eldest sons, Morgan McCoy (President) and Casey McCoy (Vice President), grow into senior management positions, taking over daily operations while Jess McCoy (Sr. Superintendant), is actively involved in the field.

Since then, the business has consistently grown and handled numerous large projects for some of the largest companies in the mining  and earthmoving industries throughout the Western United States. Throughout their history, the McCoy family has developed an exceptional staff who are considered extended family (many having worked 20+ years in the organization). The McCoy's are proud of their accomplishments and firm position within the general engineering and mining industries and are excited about the future.
