Pam Tinsley at Sign Designs is truly a gem! She cares so much about her clients and will go above and beyond to make sure you are satisfied. First of I got the best logo for my new business, after going through 4 designers- they are the best. Secondly, they made my signs for my new business and they turned out better than expected. Pam Tinsley's customer service is the best!

My family opened 2 businesses recently and we are so pleased with the design of our logos and the quality of our signs at a competitive price, we love our signs! Pam, Bud, Mitch and Jim were thorough throughout the process, it took time but it was well worth it! They were very patient with our demands and requests closing locations and opening new ones, we will be back!

It was a pleasure working with Pete and the designers at Sign Designs. Their knowledge is vast - and the many ways that Pete Michelini has given back to the sign industry needs to be commended. He volunteers on industry boards, helps steer committees, gives presentations, and is current President of the California Sign Association. An ethical and congenial man behind the scenes. Thank you for a job well done!

I own For The People Document Service Center here in Modesto, CA. My signs were in need of some major TLC. Both outside signs (which are quite large) needed many new lamps along with ballasts. My timer also needed some refreshing. Sign Designs technicians were quick to come out and assess my signage needs and also quick to install the necessary bulbs and ballasts. Now Orangeburg and McHenry is lit up and my signs look as good as new.

I just received the bill and while it was costly because of all of the repairs and items I needed, I felt it was completely reasonable. I would recommend Sign Designs for any businesses that are in need of signage help. Renne Loureiro For The People 1347 McHenry Ave. Modesto, CA 95350
