Patterson Companies, Inc. is a value-added distributor that supplies products, software, equipment, technical service and business solutions for oral and animal health customers in North America and the U.K. The company was established in 1877 as a dental company. It entered the animal health industry in 2001 with its acquisition of Webster Veterinary (now Patterson Veterinary) and expanded with its 2015 acquisition of Animal Health International, Inc.

In 2008, it was noted as having one of the lowest debt ratios among companies in the health care sector.[3] Patterson was also a member of the Nasdaq-100 until December 10, 2010.[4]

On June 17, 2010, Patterson Medical purchased the rehabilitation part of Ireland-based DCC Healthcare (Days Healthcare, Physiomed and Ausmedic) in a move that increased Patterson Medical's revenue by 16.43% (US $70 million, fiscal year ended April 24, 2010). The new companies were added to its Homecraft Rolyan unit in the UK.[5]

In December 2024, Patient Square Capital agreed to acquire the company for $4.1 billion.[6] This acquisition was completed in April 2025.[7]

## History

[edit]

The company traces its roots to 1877 and a company named Patterson's Drugs & Prescriptions, opened in Milwaukee, Wisconsin, by brothers Myron Fayette (M.F.) and John F. Patterson.

M.F. saw a future in the dental products market and moved that portion of the business to St. Paul, Minnesota. The company was family-run for more than 100 years, which added consistency in adhering to its philosophies of honest business practices and exemplary customer service. M.F.'s son John and grandson, William, served as presidents.

During the Great Depression, William Oliver Patterson took over Patterson’s Gold Manufacturing Division, a time when gold was widely used for fillings as well as partial dentures. In 1935, Bill set up the gold division as a separate company called General Refineries in Minneapolis, Minnesota. Bill ensured the survival of the company, and Patterson was able to maintain its position in the dental industry while many suppliers closed or were forced to liquidate during World War II.

At one point during that time, records show as many as 100 Patterson employees enlisted in the armed services – a high number for what was then a small company. The impact meant realigning of sales territories, calling on customers every three to four weeks rather than weekly and encouraging dentists to order by mail or telephone – a concept that, at the time, was fairly revolutionary. Bill became the company’s third president in 1949, serving till 1965, seeing the company through the Great Depression, World War II and into the “modern” eras of the ’50s and ’60s.

Founder M.F. Patterson, founder and president 1891 to 1938.

The company remained focused on dental until the 21st century when it branched out into the veterinary supplies market through two large acquisitions, JA Webster in 2001 (92.5 million dollars)[8] and Animal Health International in 2014. For about 130 years it dealt only in dental supplies.[9][10] It began selling rehabilitation supplies in 2004 after acquiring Ability One Products Corporation followed by Medco the same year.[11]

It went public on the Nasdaq in 1992 with an IPO of around 480 million dollars.[12]

The company traces its roots to 1877 with the opening of Patterson's Drugs & Prescriptions.

John F. Patterson led the company from 1939 to 1949.

## Criticism and controversy

[edit]

### FTP server data breach

[edit]

In 2016, a security researcher named Justin Shafer found 22,000 patients data on an FTP Server owned by Patterson Dental. He was reportedly raided by the FBI. [17]

### Animal welfare issues

[edit]

In 2017, photographs captured by a former employee of a Texas blood bank that Patterson Veterinary distributed products from showed greyhounds under duress. According to The Washington Post, "Pet Blood Bank owner Shane Altizer did not deny that the images were taken there, but said they predated his 2015 purchase of the company or were “moment snapshots” unrepresentative of overall conditions now." A veterinarian who visited the facility earlier in the year said she found the dogs to be in satisfactory condition.[18] On its website, Patterson said it had "ceased doing business" with the blood bank, which subsequently closed.[19][20]

### FTC antitrust

[edit]

In 2019, the FTC ruled that Patterson Dental, Henry Schein, Inc., and Benco Dental violated antitrust law by refusing to compete for the business of buying groups by colluding with each other.[21]

On November 8, 2019 the FTC's website states: "Judge Chappell held that Benco Dental Supply Company and Patterson Companies, Inc. conspired to refuse to provide discounts to, or otherwise serve, buying groups representing dental practitioners. The judge dismissed the charges against the third respondent, Henry Schein, Inc. " [22]
