To Whom It May Concern:

I have known Paul Houle and John Glenning for several years in a professional environment. I haveworked with them during the establishment of their consulting company and have been impressed withtheir desire to meet customer’s needs. Together they bring many years of technical experience andexpertise that would benefit many organizations. I have also worked with them in committee workwithin a professional organization.

I whole heartedly endorse them as people of keen intelligence, high motivation, high integrity, and richexperience.
