Five Decades of Commitment

The world’s oldest manufacturer of Doppler Ultrasound Systems, Parks Medical Electronics, Inc. was established in 1961 as Parks Electronics Laboratory. In the years before Doppler, we manufactured impedance plethysmographs, mercury strain-gage plethysmographs, hearing testers, EKG telephone telemetry and exercise EKG telemetry.

Aloha, OR

Ever since Parks made the first directional Doppler in 1965, we have consistently had the top-performing directional Doppler with respect to sensitivity – and include over twenty different Doppler devices in our full product line. Even more importantly, our business is built on our reputation for designing and manufacturing instruments of exceptionally high quality performance and dependability while providing outstanding customer service. If you ask the Bio-Med techs in any hospital with Parks equipment about our products, we’re sure they would agree.

Our offices and manufacturing facilities are located in Aloha, Oregon. We do all of our own sheet metal and printed circuit board work, as well as some work for other manufacturers in the area. Our company is wholly-owned by Loren Parks, the designer of most of the smaller units.
