What People Are Saying?

“CHR is extremely professional, responsive, knowledgeable and cooperative. Mark Collins and Stephen Earhart are very cooperative and willing to work with all professionals involved to address and solve issues through the design and building process. The end result is a quality building and very pleased customers.

I would highly recommend CHR and look forward to continued work together.”

–Greg Lewis, A.I.A.
Owner & Architect, Lewis Design Group

“Our health system replaced 4 CTs in 2 locations, virtually at the same time. Our Brownsville hospital has previously hired CHR to retrofit for at least 8 projects and I have personally been involved with 8 of the total 12 retrofits. They have always come in on budget and usually before scheduled date. This last project was on 2 different hospital campuses and Alex did an excellent job of keeping me informed of status and was a real pleasure to work with. Even when unexpected issues pop up, they adjust and do the right thing. I would definitely recommend them. “

–Linda McIntire
Director of Imaging Services, Valley Baptist Health System
Brownsville, TX and Harlingen, TX

“Very helpful and easy to work with. Professional. We will be using CHR again in the near future.”

“The removal of the CT Duo went out without any problems, loaded onto a moving van, and was running in the buyer’s warehouse within a week. The 6-slice Siemens unit came out on a Wednesday and was installed in the new location and running within 1 week. CHR made the removal and move seamless and without incident. This has been my 3rd equipment move with CHR and all have been a success.”
