Robert D. McCartney

Automotive Instructor, San Juan College

Years Teaching: 9

Years in Industry: 23

Brief Bio– As a senior in high school I began working at the Toyota dealership. I competed and placed first in state at the Ford and AAA trouble shooting contest. I Came to San Juan College and entered into the TTEN program and graduated as an Expert Technician. I worked there as a line tech and increased my knowledge and experience becoming Master Technician and then Master Diagnostic Technician. I spent some time as a shop foreman and lead technician.  I trained apprentice technicians while working at the dealers with most of them moving on to being very successful technicians.

Robert also sits on the RMATS conference Committee and has been    instrumental in preparing for the first ever virtual RMATS conference.

Ralph Mills

Collision Instructor, Pikes Peak Community College

Years Teaching: 8

Years in Industry: 20

Brief Bio – I, unknowingly, began my career in the collision industry by buying a 1970 Mustang Fastback at the age of 15. Not knowing what I wanted to do after graduation, I enrolled at Pueblo Community College’s collision program so I could finally work on my Mustang properly. I finished the program in 2000 and immediately began working at Zimmerman’s Body Shop in Canon City, Colorado. I worked there for 15 years doing every job possible. I ended my career there as an estimator and shop foreman after working nights for a few years as an adjunct at PPCC. I was given the opportunity to take on the Department Chair position at PPCC in the ACT program and continue my career there to this day. My intentions are to retire from PPCC after helping to grow the program and industry as much as possible. The Mustang is still unfinished… Ralph also sits on the RMATS conference Committee and has been instrumental in preparing for the first ever virtual RMATS conference. He has recently landed 3M as a training source for the Virtual Conference.
