For the next several years both Lee and Glenn (and their first employee Wally Lewis) worked tirelessly to build the business. 70 hour weeks were the norm and profits were continually reinvested into the business to fund expansion. In 1964 Glenn purchased Lee's share of the business and managed the store with the help of Wally Lewis. In 1972 Miner’s joined Ace Hardware, a buying co-op owned entirely by independent dealers. This strategic alliance allowed Miner’s to leverage the buying power of almost 5,000 Ace Stores, and remain competitive against the growing “Big Box” trend.

In 1982 Mike Miner, Lee’s oldest son, was named President of Miner’s Ace Hardware. Mike had worked in the store during high school and while attending Cal Poly. After college he became a licensed contractor, and later managed a successful major appliance store with his father, Lee, but eventually returned to the family hardware business. The ensuing years saw significant change: the Grover Beach Store experienced several expansions that eventually quadrupled its size, the Arroyo Grande Store was opened in 1986, the Morro Bay store in 1997, the Los Osos store in 2000, and the Atascadero store in 2002.

Today, Miner's Ace Hardware remains a family owned and operated business. Our commitments to legendary customer service and outstanding employees continues to make Miner’s the BEST and fastest growing hardware store in the County.
