What is an ASE Certified Technician? In 1972, the non-profit National Institute for Automotive Service Excellence was created to develop a way for automobile technicians to prove competency in their work. ASE has improved the quality of vehicle repair by testing and certifying automotive professionals for over 39 years. ASE offers over 40 exams that stress knowledge of job-related skills. To remain ASE certified, the individual must be retested every 5 years. If you would like to know more about ASE, please visit their website at www.ase.com.

This was hard work to transport his lawn equipment to the church each week so I decided I would purchase a used lawn mower and donate it to the church. In both instances, the community appreciated my efforts. It was at this time that small engines became part of my repair expertise. The business and knowledge of small engines has grown over time along with satisfied customers.

During my time at New England Homes, I worked for Dan Donahue, who was the owner of New England Homes, until he sold his business. It was Dan who encouraged me to branch out on my own and begin this small business venture. My expertise coupled with Dan’s tremendous business knowledge and all he has taught me over the years are the three important factors in your
