Ingersoll Watson & McMachen

The firm was initially established in 1952 by Wayland D. Ingersoll, a Professional Civil Engineer and Licensed Land Surveyor, as a proprietorship offering engineering and surveying services. Mr. Larry G. Watson, P.E. and Mr. Allen H. McMachen, P.S., both having been employed by Mr. Ingersoll since 1959, joined with Mr. Ingersoll in 1969 to establish and become principals in Ingersoll, Watson & McMachen, Inc.

Upon the death of Mr. Ingersoll in 1970, the firm continued to operate under the ownership and direction of the remaining two principals. Mr. Larry G. Watson retired from the corporation in 1991. The present corporate structure was formed in 2002 upon the retirement of Mr. Allen H. McMachen. Currently, Mr. Randy B. Ligman, P.S. is president and Mr. Patrick D. Flanagan, P.E. is vice president of the corporation.
