A Timeline

Sigma Supply of North America has been a certified women-owned business by the Women’s Business Enterprise National Council (WBENC) since 2004. We are proud of this certification and the opportunities that it provides for our business and for our clients as well. WBENC works to foster diversity in the world of commerce.

The Early Years

Dan Hamby grew up fishing on Lake Hamilton in Hot Springs, Arkansas. Hot Springs is where he would meet his wife, Martha, and the town would serve as the headquarters of Sigma Supply.

The 1960s

During the 1960s, Dan and Martha Hamby married and moved to Boston, Massachusetts where Dan had the opportunity to get his start as a MYSTIK Tape salesman. He was promoted to regional manager shortly thereafter. 

The 1970s

In 1970, Martha and Dan moved back to Hot Springs, Arkansas to start their family-owned business, Sigma Supply.

In 1972, Sigma Supply moved into its second office and warehouse on Valley Street in Hot Springs, Arkansas, depicted above.

Half of the building on the right belonged to Sigma Supply and the other half housed a local law office.

Several years later, Sigma Supply bought out the other owners for the use of the full building. They later purchased the building to the left for extra storage and trailer parking capability.


In the beginning, Sigma Supply shared its first office with a law firm. The secretary answered a black phone for the law office and a red phone for "Sigma Supply." The secretary also kept track of Mr. Hamby's notes and messages while he was making deliveries and sales calls.


Dan made deliveries in his El Camino. His children, Maggie, Banks, and Scott, rode along and helped each summer.

The 1980s

Maggie, Banks, and Scott joined the family business.


Sigma Supply opened its first branch location in Fort Smith, Arkansas, on Wheeler Street.

Paul Breitenberg joined Sigma Supply to start a second branch location in Jonesboro, Arkansas, on Willow Road.


Sigma Supply relocated its corporate offices from Valley Street to its current location at 824 Mid-America Blvd in Hot Springs, Arkansas.


Dave Ezell joined Sigma Supply, and soon after, the Fort Smith location moved into a larger facility on Towson Street.

Within one year, Sigma Supply was expanding the Towson Street location by an additional 36,000 sq. ft.

Sigma Supply also made its first expansion to the 824 Mid-America Blvd. location in Hot Springs, Arkansas.


Sigma Supply opened a third branch location in Memphis, Tennessee, on Airport Road.

One year later, the company merged the Jonesboro and Memphis locations into a larger facility in Memphis, Tennessee, on Millbranch Road (pictured above).


This year brought about the second warehouse expansion to the 824 Mid-America Blvd. location in Hot Springs.

In this expansion, Sigma Supply expanded its corporate offices and boardroom and added an employee training center.

Mr. Hamby once said he envisioned "multiple groups of Sigma employees passing through the new training center annually, learning new products and processes that would enhance the customer experience."


In 2001 the customer demand for West Coast operations led the company to open its North Las Vegas facility to reduce delivery time and improve customer service.


In 2003, the Hamby Family launched Sigma Supply of North America as a WBENC business.

Note: Over the next several years, due to rapid recognition that SSNA received from Fortune 100 companies, the Hamby family decided to move Sigma Supply of North America to the forefront of its sales & distribution network.


During this period, Sigma began providing customer support out of the Richmond, Virginia area.


Based on the tremendous growth in the Memphis area from the Millbranch Road location, Sigma opened its first design-build warehouse in Lake Cormorant, Mississippi, on 1 Sigma Drive in 2007. This 254,000 sq. ft. facility became the new flagship of the company.
