"Great service" I needed to have an annual state inspection performed in my CRV and Christian Brothers performed the service quickly and efficiently with friendly, courteous attendance. I would highly recommend this company. - Scott
"Jeremy is an asset to the organization and a caring person" I ran out of gas and was walking to a gas station when I passed by the Cypress location. Jeremy came outside and didn't ask - he TOLD me he was going to give me a ride. amazing individual. He not only gave me a ride but he filled up my gas can for me. In today's world, it is not common for this type of thing - unfortunately. Thank you to him and congrats to Christian Brothers for hiring a true professional. I have owned a company, been in sales and Customer service for 26 years. This is why people do business with others. I will be a client from now on! - RA
