What our clients say

Cornerstone cares about community service

Attention Tony Leeber Jr.

We would like to say, you “WOWED” us with your generous donation of a quartz countertop and installation. We can see why your customers are singing your praises as your work ethic is unbelievable.

I called your company late one Friday morning asking for any used cabinets or countertops that were being removed from a job. The response was that you would call back in 5 minutes. Typically that means, “NO,” but to my surprise in 5 minutes your office called back and offered a new countertop. Two hours later you sent a crew over to measure for the new top. Both John Manfredi and Jaime Landon were very professional and the top was installed last week.

We are a 501c(3) Non-Profit Organization that feeds homeless, out of work, and low income families. Our food is donated by The Harry Chaplin Food Pantry, The Midwest Food Bank, and Publix Grocery Stores. We can’t thank you enough for the countertop. Thank You and God Bless You,

Dear John and team,

Thank you all so much for providing the lunch for our volunteers at the Christmas warehouse on Wednesday, December 18th. During the Christmas distribution, we were able to serve over 4,000 children with toys and gifts and food for the Christmas holiday.

It was such a pleasure to meet you. I would like to invite you and your team to tour our 182 bed residential shelter and see our programs. We briefly discussed your desire to do a Bible study on site, and I would like to help in any way that I can to facilitate that goal. Perhaps we could talk more early in this New Year.

Hope that you had a very Merry Christmas and will have a blessed new year.
