What Our Clients Say

Hear directly from the families we’ve had the privilege to serve.

I was very pleased with the final product and the quality of the work that went into the monument. I would recommend Lock City to all my friends, family, and whoever is reading my comment, you'll be more than satisfied.

Rodger White

My family has used Lock City Monuments numerous times over the years. Craig takes a lot of pride in his work and went above and beyond to make sure our headstone was ready and installed prior to our gravesite service. It meant so much to our family, thank you so much!

Lisa Portelli

My family is so appreciative for the beautiful headstone Lock City Monuments created for us. If we could give 10 stars, we would. Our thanks to Craig Cartmill and his team.

Deanna Sterling

My family has been customers of Lock City Monuments nearly since it’s opening year almost 70 years ago. Craig and his staff were warm and personable to deal with when we picked out my mother’s stone, and in going through her family’s papers we discovered that her parent’s stone had also been purchased from Lock City and Craig’s grandfather 68 years prior. It was quickly evident that their level of service and commitment to excellence has not changed at all throughout the generations. Would highly recommend.
