Randy DeVries

Founder / President

Randy started Site Services in 1982 as a small family owned company. The company initially provided Sealcoating and Striping services and he ran the company from the office in his basement. Now 30+ years later Site Services provides the full line of pavement maintenance services along with asphalt milling and paving and more recently Roller Compacted Concrete. The company has grown out of the basement to its current office in Highland, IN. Still very much a family business, Randy’s sons Todd and Jamie as well as son-in-law Mike are vital participants and the leaders of the organization. Randy spends his time away from Site Services with his lovely wife Cindy and their 6 grandchildren!

Todd DeVries

Vice President / Operations Manager

Todd has been with Site Services since 1990. He started off striping with Randy in his early teenage years. Overtime he learned all the different types of work we perform in the field; next working thru the different positions in the office to learn all aspects of the business. Over the past 20 plus years his many roles and responsibilities have grown and changed. These roles currently include co-owner, vice president, and operations manager. Todd continues to spend time in the field working on jobsites. Todd is married to Carrie and he has two wonderful children.

Mike Schutt

Treasurer / Sales Manager

Mike’s tenure with Site Services began in 1998. He married Lisa DeVries (Randy’s daughter) in ’97, so it seemed like a logical step. Mike started in the Striping crew and has worked on all the crews during his time at Site Services. That experience in the crews has helped his understanding of the business operations, and has been on the Sales side of the company now for the past 15 years. Mike is currently the Sales Manager of the office crew. He has developed estimate sheets, job costing procedures, marketing programs and online scheduling for the crews. Mike is busy outside of the office as he helps with 4 boys at home. He enjoys coaching his kids little league teams and plays bass guitar in his church’s praise team band.
