“Because of DPSI's excellent service and response time, we have not experienced any major downtime with any of our support equipment.”

It is with great pleasure to write this letter of recommendation.

For the past 3 years your company and technical personnel have supported our mission critical sites with expertise and care.

I have had some dealings with other service companies and none have been able to measure up to your philosophy of customer service and attention.

I cannot say how many times your engineers dispatched in the middle of the night or at a short notice or saved our site(s) from going down.

Your selection of engineers reflects greatly on their abilities and competence.

I could go on for pages of how your personnel at DPSI have done an incredible job for Concert and my operations team.

I want to thank you and your engineers for all your support and continued excellence to Concert.
