Alvamar’s two Lawrence golf courses are about to join the roster of a major course management company.

On Tuesday, Billy Casper Golf Group will take charge of the day-to-day operations of Alvamar’s recreational assets: the two 18-hole golf courses, the two pro shops, the driving range, the dining room and other operations now owned by 120 shareholders.

All 120 employees will remain at the service of the operation’s 1,000 members, their guests and others who arrive at the complex off Crossgate Drive in western Lawrence for golf, swimming, dining and other activities.

“To the members and the patrons who play here, it will be absolutely seamless,” said Dick Stuntz, who will remain general manager.

Shareholders had offered the recreational assets for sale late last year for $6.5 million, and had secured a contract that was supposed to close by year’s end. But when that deal fell through — a deal that would have had an out-of-town buyer hiring the Casper group as manager — the owners’ own leaders decided to enter management negotiations of their own.

The management agreement stretches through the end of 2014, during which time Alvamar leaders plan to continue seeking a buyer so that shareholders — many of them investors since the project started in the late 1960s — can sell their shares and move on, said Bob Johnson, chairman of the Alvamar Board of Directors.

“We’re doing everything we possibly can to enhance the value, and wait for the marketplace to improve to the point where there are more people who have the resources and the interest in acquiring a golf course recreational operation,” Johnson said.

No major changes are expected with the management switch, other than expectations for the new Alvamar Golf Management Corp. — to be a wholly owned subsidiary of Alvamar and run by the Casper group — to put up more black numbers on Alvamar’s balance sheet.

The Casper group brings the buying and negotiating power of a 125-course group to a single operation with two courses, Johnson said, and plans to boost sales and memberships.

“We’re going to increase our financial performance,” Johnson said. “And, in the process of doing that, we’ll enhance the value of the facility and the corporation, which we think is in the shareholders’ and the members’ and the community’s best interest.”

The Casper group also manages Cypress Ridge Golf Course, an 18-hole municipal course in Topeka. The course opened in 1954, and until 2004 had been known as Topeka Public Golf Course, two years before the Casper group signed on.
