Zach Wilkinson

Owner

PE, RLS, GC(BC-A,b)

Zach grew up in Portland, Tennessee and had an interest in real estate and the land development process from a young age. The influence of Zach’s grandparents and father, who were in the real estate industry, inspired Zach to obtain a civil engineering degree from Tennessee Technological University and eventually attain his professional engineer, surveyor, and general contractor licenses.

Since high school, Zach worked for various local engineering and surveying firms along with spending 12 years with the City of Gallatin in the role as an engineering project manager and the City Public Works Director. During this time, Zach has developed several residential construction projects of his own, including residential rental and subdivision developments.

The experience of working on both the regulatory and private sector side as a consultant and project owner/client has led to his deep understanding of all aspects of the development process, including the challenges of navigating financing, real estate acquisition, regulatory hurdles for project approvals, construction, project closeout, and eventual long-term maintenance.

Zach’s deepest passion lies in the surveying aspects of the development process, but the wide variety of knowledge he has obtained through the years is what inspired him to found Cornerstone Development Services and partner with the other team members of Cornerstone, including a real-estate agent and property manager, to have a one stop shop of knowledge and resources for the development process.

When he’s not working, Zach can be found doing anything outdoors, but he especially loves riding and racing hard enduro dirt bikes. Zach married his college sweetheart, Tiffany, who works for the Sumner County Board of Education. They have two children, Charlie Kate and Corbin. Together they enjoy traveling, sailing, and scuba diving. They are blessed to live on the same farm that Zach grew up on in Portland, Tennessee!
