HVI team

Our Team

High Voltage, Inc. is family-owned business built on strong foundations of innovation and integrity in manufacturing HV test equipment. Dedication to this industry began in the 50s with Peschel Instruments, founded by Stephen Peschel. His son, industry leader Stanley Peschel, went on to earn 23 patents and founded Hipotronics and HVI.

Today, the HVI executive team is led by Stan’s sons Stephen and Michael along with his nephew James Grayson.

Many of HVI’s key staff members worked for Hipotronics until HVI was founded in 1997, maintaining a rich tradition of industry expertise and unparalleled customer service.

The staff members who interact regularly with HVI customers are shown below. The team is always ready to handle complex challenges and eager to help customers find the best solutions for their HV test equipment needs.
