Tom von Kuster of David C Bell Investment Company became MAC president 14 years after his father and just as Operation Up-Date was completed. Charles Doell, superintendent of the Minneapolis Park System, followed. During his presidency, in July 1962, the tunnel to the new Northstar Center across Second Avenue opened, giving clubhouse access to the Skyway System.

Maurice Hessian Jr., the son of the MAC’s 1925 president and a lawyer in the firm of Thompson, Hessian, Fletcher & McKasy, presided over the glorious Golden Anniversary celebration in 1963. He was succeeded by Dick Massopust, of the CPA firm Peat, Marwick & Mitchell.

Paul Foss of Paul Foss Printing and Lithography became the 24th MAC president in 1966; the year Serio Rossi succeeded Fred Andrews, who retired after 23 years as general manager.

In July of the following year, the MAC bought the lot that was behind both the clubhouse and WCCO Building for $400,000, a record price for downtown real estate. Declaring it an excellent buy even at that price. Paul Foss appointed a committee to launch Operation Up-Date II, which envisioned additional athletic facilities on the lot. Over $1,000,000 was marked for the improvement program, of which $450,000 was expended to rebuild and redecorate 75 guest rooms. From 1946 through 1968, the club had spent $3,100,000 in remodeling.

Judge Luther Sletten and Bill Boyer, president of Bill Boyer Ford Company, were the 25th and 26th presidents. Darrel Holt, president of Towi Realty Company, and Gerald Uttley of the Minnesota Federal Savings and Loan Association followed them as the next to lead the MAC. In 1970 Seldon Coombs retired after 27 years as athletic director, handing the torch to Jerry Grebin. In 1971 the first tennis tournament was conducted. One year later, Emeritus memberships were introduced for longtime Resident members 65 years of age and over.

Gil MacPhail, director of the MacPhail Music Center, and Bob Bjorklund, agency manager of Bankers Life Insurance Company, were the next presidents. A new athletic facility was planned for the property that had been acquired seven years earlier, but bids were rejected because they were substantially higher than expected and also because of a troublesome easement on the property behind the WCCO Building. The Board of Directors, however, gave the go-ahead for construction of a running track above the third-floor gymnasium. Work began and was completed in 1974. Reginald Faragher had retired in 1973 after 26 years as publisher of the MAC Gopher.
