Testimonies
"Cascadia MRO has been wonderful to work with. Results are consistently delivered in a timely manner, communication is prompt, and the level of service has been excellent."
Emanuel Carvalho - DNA Drug Testing
"It’s not in my nature to take the time to express my thoughts about a service received. However I make the exception for the MRO services of Dr. Nobel and his assistant Christina. As a collector for thirty years one of my clients had a bad experience with the MRO that I was using and insisted that I find someone else to service his account. I began my search and settled with Dr. Noble and Christina. They have been very helpful working with my client to gain his confidence in the system. Watching how they gained the confidence of the person that was hurt through a miss understand showed me that I should move all of my clients under their care. As I use up my supply of collection forms I will be be placing Dr. Noble on the upper right corner of the COC.
Very glad to have found CASCADIA MRO SERVICES ."
