Conceived in 1969, Thunder Hills Country Club was the vision of five individuals who wished to develop and build the second planned golf course community in the State of Iowa. Those five individuals were Gordon Cunningham, Peter Beeves, C.J. May, Jr., Frank Dunn, and Bob Frommelt, who was the first president of Thunder Hills Country Club. This group was instrumental in the purchase of the Burds and Harris farms just east of Peosta, Iowa.

Their vision was to build a residential community of paved streets with homes backing up to an 18-hole championship golf course. The five embarked on an aggressive membership program to reach 300 members as they built and developed the planned golf course community. The club would have an initiation fee of Five Hundred Dollars ($500.00) and monthly dues of Twenty Dollars ($20.00).

The five decided that the development should be named with an Indian name and, after searching through 1000 names at the public library, settled on Thunder Hills. Thus Thunder Hills Homeowners Association and Thunder Hills Country Club came into existence.

In 1971 Thunder Hills Country Club opened the front nine featuring watered tees and greens and the new Clubhouse. The swimming pool and back nine holes opened for play in 1972. The three tennis courts opened in 1973.

In August 2002 the Board formed a Facility Study Committee to study and make a recommendation for a strategy to improve or replace the existing Clubhouse. The strategy was designed to enhance and grow the membership.

The membership approved the conceptual plan in 2003 and excavation work began in October of that year. On May 22nd, 2004 the new Clubhouse opened.

In 2016-17 the Club embarked on a $1,000,000 renovation project. On the golf course, all bunkers were renovated with new drainage, liners and sand.

Improvements in the pool area included: a new Kiddie Pool with water features, new lights and re-painting of the main pool, re-painting the pool deck, Wi-Fi installation, addition of three shade awnings and replacement of the main pool heater.

The Tennis/Pickleball courts were also completely refurbished with a new surface, fencing and lighting. A basketball hoop was also installed.

In June 2021, a new 4,200 square foot pool and 3,700 square foot cabana will open.

As stated in the Mission Statement: "We are committed to providing an excellent golf facility as our highest priority with continual investment to enhance the value, tradition, and overall quality of the Thunder Hills Country Club experience".

1969   In 1964, Gordon Cunningham resigned as the Golf Pro at Bunker Hill Golf Course in Dubuque, IA to found Midwest Irrigation Co. With partners, Peter Beaves (a plumber by trade) and Mayhew Bennett their mission was to install golf course irrigation systems.

By 1966, the team decided they should expand by opening a 51-acre, nine-hole golf course known as the Red Course at Lacoma Golf Club in East Dubuque, IL.

In 1969, Gordon Cunningham, Peter Beaves and Midwest Irrigation's business attorney C.J. May, Jr. and banker Frank Dunn (East Dubuque Saving, East Dubuque, IA), and Gordon's neighbor Bob Frommelt (Frommelt Industries, Dubuque, IA) conceived of a vision to build a residential community with homes backing up to an 18-hole golf course. The idea of Thunder Hills Country Club was born.
