Twin Oaks Family Dental

Working with John and his team was the perfect match for my goal of converting a bakery to a dental office. JHOOKER was able to coordinate the entire process, from city approval and inspections in a timely manner and help me complete my project efficiently and with excellence in craftmanship. Great experience with the entire process from top to bottom.

Rich Francis

First Baptist Church, O’Fallon

The JHOOKER project team was outstanding. They understood our needs and were extremely helpfully throughout the entire process. I would highly recommend them.

Jessica Stroupe, DVM

Howard County Veterinary Service

I was very happy with JHOOKER Construction Services for our renovation project. The communication was great and the attention to detail was phenomenal.  Having an on-site project manager to oversee the project was very important and helpful. They turned my vision into a reality, and I love showing up to work every day to my beautiful clinic!

Rick Bender

West County Animal Clinic

Our new building was completed on time and within budget. Also, their employees are easy to work with and professional. No surprises. Also, the sub-contractors chosen were excellent who cared about quality as much as we did. Total respect for John’s team.
