"Mary, I'm retired from a lifetime of consulting and teaching in the field of civil/environmental engineering. With three graduate degrees from MIT in the area of water and wastewater, I think I know competence in the field, and your knowledge and teaching style were just great. So thanks for yesterday. You made my day."
- Professor, Seattle University

"Garrett Yates was very personable and emphasized participation. He delivered the material in an effective manner."

"I didn't think I would understand this class, but I have come out of this class a little smarter, and more aware of cross connections and backflow."

"Derrick Yates was knowledgeable, congenial and has good teaching ability."

"Mary L. Howell was very good. She delivered the material in a way that made even the complex seem simple. The training material was very good and the manual was well written. I found the inspection very helpful."

"Ray Johnson did an outstanding job presenting in a way that was easily understood."

"Probably the most informative, useful, and definitive class on testing and understanding backflow assemblies."

"I feel that the course gave our personnel the knowledge necessary to begin the implementation of our cross connection control program."

"I think this training class is very helpful. It was what I expected, and more. The instructor was informative and helpful. She tried very hard to see that we all understood the material."

"I got out of the class what I needed to begin my cross-connection program. The instructor and material were excellent. I would like to see these programs continue."

"I appreciate the knowledge that our instructor acquired to make association with our own state. The program has given me more confidence in getting started."

"The course was well prepared, informative, and helpful. I learned how to apply this program development to my own system."

"The course was well presented and we were given useable information by someone who does what we do and knows what we need to learn and understand. The manual was used most effectively."

"The course was comprehensive enough for the purpose of establishing a cross-connection program. I felt I received what I needed to get a program off the ground."
