Air Pollution Testing, Inc. (APT) has been serving clients in a variety of industries since 1991- Since this time, sales, staff and client base have been steadily expanding to our current size of over 40 full-time employees and over three hundred clients. This growth can be attributed principally to providing outstanding customer service, quality data collection and professional reporting.

At APT, our goal is to compere more on quality than price; sending out degreed environmental professionals and state-of-the-art equipment is not inexpensive. APT's philosophy is to win projects as the best value rather than the cheapest option by providing an unsurpassed level of service at a fair price. This approach seems to be working, with better than 85% of our sales coming from repeat customers - with much of the remaining work representing the forging of new relationships.

At APT, customer service means rapid response (mobilization can happen as quickly as the day of your call), full-time accessibility to key personnel (many clients have APT home telephone numbers for weekend consultation and rush scheduling), and the ability to get the job done.
