About Us

Caliber Appliances is powered by the collaborative efforts of Randy Rummel and Dan Nichols, seasoned veterans of the appliance industry who have been developing superior products for the commercial and residential industries for over 50 years combined. Randy co-founded Dynamic Cooking Systems (DCS), a leading manufacturer of premium cooking appliances, and served as President and CEO from October 2003 through 2004 prior to their sale to Fisher & Paykel. Dan started as DCS’s first principal designer in 1993 then grew to the role of Vice President and General Manager prior to leaving DCS in 2007. Randy and Dan rejoined forces to consult for the appliance industry through Revolve Design. Together, they began to cook up Caliber Appliances when they realized the demand for custom luxury grill and ranges that empowered home cooks to create restaurant-quality meals from the comfort of their own kitchens and backyards. This vision of True American Luxury drives Caliber Appliances.

Caliber Appliances launched in 2013 with a made in the USA, customizable and design-focused outdoor product line that immediately won several design awards. In 2016, the much-anticipated indoor estate-scaled line of 36”and 48” all-gas professional ranges and rangetops launched. This line was designed in collaboration with the country’s top architects and designers, and provides complete color and trim customization, making Caliber the first American manufacturer capable of producing entire custom cooking suites for home culinary enthusiasts.
