About Us

The Sentinel Imaging Group has a rich and diverse history in the field of medical ultrasound imaging with our roots dating back to the very earliest days of medical ultrasound imaging.    With almost 40 years experience in ultrasound field service, Sentinel Imaging is more than equipped to meet the challenge of keeping your equipment running and imaging perfectly with minimum downtime.

Our owner and founder was a factory trained ultrasound field engineer originally with ATL before they were acquired by Philips and then subsequently as a luminary field service engineer with Philips into the  2000’s.

Imaging is a delicate area for our clients, whose systems often require immediate attention. Our promise to you is that we will never stop until you are satisfied and you can take great comfort knowing that your equipment is in the hands of the team that cares.

Here at Sentinel we truly understand the ins and outs of imaging solutions. We have been one of the leading authorities in imaging sales and repair solutions and look forward to sharing all this with you.

Bob Davies , our founding partner and Director of Service, can speak to a long history in ultrasound service and support. Bob signed on with ATL as a customer service representative in 1980, when diagnostic ultrasound was still in its infancy.

After an enduring career with ATL Philips spanning nearly a quarter of a century, Bob partnered with his son Brent to launch The Sentinel Imaging Group.

With a lifelong passion and singular focus on delivering an exemplary level of service to his customers, Bob is still at it today and going strong.

Just ask and he will tell you that even after 38 years, the tenets of SERVICE EXCELLENCE remain simple and they remain unchanged :
-Give your customers the service and support they need , and give it to them when they need it if not sooner.
-Do it in a manner that consistently exceeds their fondest expectations.
-Keep them informed every step of the way, and never leave them in the dark.
-Listen to them and value what they have to say , not only as customers, but as fellow human beings.
Today, every one of our employees has internalized these rules to guide them in their daily interactions.
Sentinel’s employees are empowered to find new and creative ways for our customers to win. Why? because when our customers win we all win!
