Sand Valley Golf Resort offers up Wimbledon experience in central Wisconsin

From the On Wisconsin: Read special coverage of state's culture, people series

NEKOOSA — When famed golf course developer Mike Keiser and his two sons decided in 2013 to buy 1,700 acres in central Wisconsin, the idea was to take advantage of the massive amount of sand left behind thousands of years ago from receding glaciers.

Their Sand Valley Golf Resort now has three courses, and a fourth is under development. Last year, the resort drew golfers from all 50 states and 20 countries, some arriving via private jet at Alexander Field in nearby Wisconsin Rapids. The resort has been praised by national golf publications and has become part of golf vacation tours that include other prime Wisconsin destinations like Whistling Straits north of Sheboygan, Blackwolf Run in Kohler and Erin Hills near Hartford, which hosted the U.S. Open in 2017 and will host the U.S. Women’s Open in 2025.

Golfers approach the final hole on the Mammoth Dunes course at Sand Valley Golf Resort near Nekoosa. The resort has two other courses and a fourth is being designed for the 9,000-acre property. 

Now the Keisers are touting a new amenity that’s creating a buzz not in golf circles but those who use a racquet and dream of Wimbledon.

Sand Valley has built one of the largest collections of grass tennis courts in the country. There are no fences, only dunes of sand and pine trees surrounding the 15 courts that are grouped in threes on five pitches next to the golf practice range.

Pam Hammond, left, executive director of the Wisconsin Tennis Association, looks over one of the three-court pitches at Sand Valley Golf Resort in Adams County. The 15 tennis courts are the only public grass courts in Wisconsin.

But for those wanting to check their lawn game skills at the facility, which is open to the public, be aware. The ball reacts differently when hit on a grass surface cut like a golf green. Primarily, the ball doesn’t bounce as high, meaning those who shun hustle may find themselves at love more than not.

“You really can’t overrun a ball here,” said Kate Carroll, of Hartford, who last week played for the first time on a grass court. “If you don’t come up on it you’re dead in the water.”

Frank Meier, of Monroe, took a vacation day last Wednesday from his job at a stone company and had a similar experience, but one he truly relished.

“This is really cool,” Meier said in between points. “The ball does not come up much. It kind of goes forward but it does not come up.”

No special shoes are required but the resort recommends players wear shoes with a flatter sole. Regular cans of tennis balls can be used but the resort’s pro shop also sells, for $4, cans of special balls that are white and better suited to the grass game. And the cost to play is reasonable — $20 per hour per court. So a group of four playing doubles can play three hours of tennis for just $15 each, although the resort recommends a ball boy or ball girl for $10 an hour.

Lyle Schaefer, founder of Lyle Schaefer Tennis Academy in Madison, brought a group of his students to Sand Valley Golf Resort last week to play on the resort's grass tennis courts. 

Meier was with a group of adult students with the Lyle Schaefer Tennis Academy in Madison. Schaefer, a veteran tennis coach who has been teaching tennis for over 50 years and has played in state and national tournaments, made his first visit to Sand Valley last week. He’s played on grass courts over the years and said one of the advantages to grass for older players is that it’s easier on the body.

“You can do six or seven hours out here and you’re not feeling too bad,” said Schaefer. “I love this setup.”

Glen Murray, far right, general manager of Sand Valley Golf Resort, speaks with tennis players at the resort's grass court tennis complex. The courts are open to the public and can be rented for $20 per hour.

While there are some private clubs around the country with grass courts, those open to the public are a rarity, with most located in Florida, New York and California. The exceptions include The All Iowa Lawn Tennis Club — which has a single court built in 2003 on a family farm near Charles City, Iowa — and four in Baker City, Oregon, built by Don McClure, a local jeweler, and dubbed WimbleDon Grass Courts.

Sand Valley opened three courts last July and the rest earlier this month. It now rivals the Newport Casino Lawn Tennis Club at the International Tennis Hall of Fame in Newport, Rhode Island, which has 13 grass courts and since 1881 has been hosting the U.S. National Lawn Tennis Championships.

In the early 2000s, Craig Haltom, who was working for Madison- based Oliphant Golf Construction, began scouring the state looking for a unique site for a golf course development when he found a large tract of land in Adams County owned by a timber company. But when the financial markets began to sour in 2007, Oliphant went out of business and the plans were set aside but not forgotten. Haltom ultimately connected with Mike Keiser, who purchased the property in 2013 and has 160 founder investors who each ponied up $50,000 for the project that now has three golf courses, a fourth under design and one of the largest collections of grass tennis courts in the country.

Rob Wright will be the teaching pro at Sand Valley beginning next month and is working for Cliff Drysdale Tennis, which manages some of the most well-know tennis destinations in the country. Wisconsin is now on that list and Wright, 29, not only brings grass court playing and teaching experience to the resort but also an English accent. He grew up just north of London and has been playing tennis since he was 10 years old.

“Most people haven’t played on grass and the style is completely different,” said Wright. “The location of the courts is kind of out of the blue but the fact they have 15 is just unbelievable. I think it’s going to be a great program.”

But it’s also a work in progress for the resort as it learns how to care for grass that takes a pounding, especially at the baseline, where it can quickly become worn. That’s why each pitch has lines for five courts but only three nets which can be picked up and moved. The resort also only allows nine courts to be used at a time so the grass has a chance to heal.

Aldo's Farm & Table is a restaurant at Sand Valley Golf Resort named after environmentalist Aldo Leopold. The resort is planning to partner with Mid-State Technical College, with four central Wisconsin campuses, to create a culinary school at the resort.  

Jimmy Humston is the resort’s agronomist who is monitoring the courts and trying to determine which will hold up better in Wisconsin, those with fescue, common on golf fairways, or those with ryegrass, which is used at Wimbledon. Humston grew up in eastern Tennessee and worked for a time at Augusta National Golf Club in Georgia but this is his first experience with grass tennis.

“This is kind of a year of trial and error,” said Humston. “After every day of play you have to come out and monitor and see what kind of damage you have and adjust from there. Any traffic, even walking on it or mowing it, is considered a stress. It’s how much stress can it take and what can we do to combat that.”

Fat tire biking is one of the many offerings at Sand Valley Golf Resort in rural Adams County. The resort also has bocce ball, hiking trails, grass tennis courts and a restaurant.

The addition of grass courts to the Sand Valley experience is keeping true to the Keisers’ plan to encourage more people to use what is now a 9,000-acre property for more than just golf. Fat tire bike trails are being developed, there’s bocce ball, hiking trails, and Aldo’s Farm & Table, a restaurant that overlooks the first and finishing holes of the Mammoth Dunes course and is located inside the 30,000-square-foot club house.

The resort also wants to create a culinary school and is already hosting weddings, corporate and other private events. Homes are being built around the property and the resort’s 114 guest rooms are 90 percent booked for the season.

Housing continues to be built around the courses at Sand Valley Golf Resort. The development also has 114 guest rooms, of which 90 percent are reserved for the season. Last year, guests from all 50 states and 20 countries played golf at Sand Valley.

With the addition of tennis, a whole new user group is headed to Adams County, one of the state’s up-and-coming tourist destinations. The state Department of Tourism reported on May 6 that direct tourism spending in the county rose 10.2% to $218.6 million, far outpacing the state, which had a 4.9% increase in direct spending. Officials at Sand Valley envision tennis adding to the tourism bottom line with college and high school invitationals, clinics, camps and professional instruction by Wright.

There is no other tennis setting in Wisconsin like the one at Sand Valley Golf Resort near Nekoosa in Adams County, where 15 grass courts are set among sand dunes.

On June 29, for example, tennis legend John Powless, of Madison, the No. 1 tennis player over 85 in the world and former University of Wisconsin basketball coach, will lead a one-hour clinic at Sand Valley as part of “Wimbledon in Wisconsin: A Grass Fed Family Tennis Event,” being put on by the Wisconsin Tennis Association. The all-day event will allow players of all ages and abilities to experience grass courts and take part in other clinics and organized match play. The cost is $5 per person or $10 for a family.

Sand Valley Golf Resort's 9,000 acres are surrounded by ATV trails but the vehicles are prohibited at the resort in rural Adams County.

Pam Hammond, executive director of the association, brought her leadership team to Sand Valley last week to scope out the setting and determine where to place tables, seating, water stations and registration. Hammond is expecting well over 100 people and will skip the clotted cream, which is served at the All England Lawn Tennis & Croquet Club. She plans to pair the strawberries with good old Wisconsin cheese at the event, which will take place two days prior to the start of Wimbledon.

“There was a little concern among the staff when we started talking about this, and would players come to this part of the state,” said Hammond, of Fond du Lac, whose organization has about 7,700 junior and adult members. “Now everyone’s like super pumped. They’re excited that it’s here and we think it has a lot of potential for tennis in Wisconsin.”
