Portable Oxygen Solutions (POS), the North Carolina-based oxygen concentrator specialist, has been placed at No 1,055 on Inc.’s annual list of America’s fastest growing companies.

The Inc. 5000 list is compiled and ranked to represent percentage revenue growth over a three-year period of US-based companies which are privately owned and not subsidiaries of larger businesses. Annual revenue must reach at least $100,000.

POS claims its “patient-first approach to selling oxygen concentrators has proved to be the secret ingredient” which has allowed it to enjoy spectacular growth over the past year.

The oxygen supply company was only formed six years ago and aims to improve the quality of life for oxygen therapy patients, predominantly those diagnosed with Chronic Obstructive Pulmonary Disease (COPD).

POS sells portable oxygen concentrators (POC) and other medical equipment, as well as offering advice about products for particular needs.

“We are happy to receive this award from Inc. It lets us know that our team here is doing an amazing job, and that we’ve developed a recipe for our success,” said Todd Flesch, POS owner.

“But for us, it’s ultimately about our customers: the men and women we help every single day. We take great pride in providing advice and guidance to help each of our clients select the right portable oxygen concentrator that fits their specific needs and life style.”

Inc. magazine has been doing the annual list of 5,000 fastest growing companies in America since its first issue in 1979.
