Who We Are

Who We Are

The company’s founders and directors, John Hauck, Doug Johnson, Jerry Hu and Mark Johnson, have worked together with leading rehabilitation providers to develop the Lite Run technology. Together they have over 60 patents for medical technology and more than 30 years of engineering and medical system experience.

In the midst of a prolific cardiac medical system development career, John Hauck first turned his attention to developing a system that would help him keep running as he struggled with knee pain. He connected with Doug Johnson, another recreational runner and inventor, and the two began to collaborate on a system for walking disability. After some false starts, they invented a new way to take body weight off using air pressure in a special pair of pants. Machine designer Mark Johnson joined the effort and they built a system with mechanical and pneumatic controls to run in the pants on a treadmill. “I was delighted when I found that I could run for an hour at up to half of my body weight!” Hauck recalls.

It was clear that this system would help more than recreational runners. The three Lite Run founders began collaborating with Sister Kenny Rehabilitation Institute and North Memorial Hospital to build a prototype walker version for gait therapy. The therapists liked it so much that they volunteered their time to help test it. “The prototype proved so compelling that we just had to step up our efforts and develop a product,” Hauck says.

Our Market
The Lite Run system serves a large and growing market of patients and health care professionals. Lite Run has the potential for rapid return on investment in health care settings. From hospitals to long-term care and outpatient settings, physical therapy departments can experience greater productivity, with physical therapists seeing more patients per PT hour. As a result, the system has the potential to pay for itself in just one year.

John Hauck

President, Director

Mr. Hauck started his career at Cardiac Pacemakers Inc. in Arden Hills, Minnesota and in 1993 he joined startup Endocardial Solutions (ESI). In 2000 he left his Applied Research Director position at ESI to found EM Vascular Inc., developing technology for electrically mediated angiogenesis, which was later sold to ATS Medical Inc. Mr. Hauck then rejoined ESI, where he was instrumental in developing the NavXTM heart mapping technology.

St. Jude Medical acquired ESI in 2004, and Mr. Hauck directed a department responsible for robotic catheter technology development with a multi-million dollar annual budget. He recently left his position as Senior Engineering Fellow at St. Jude to pursue the Lite Run mission full time. Mr. Hauck holds over 60 patents and is a Senior Member of the Institute of Electrical & Electronics Engineers.

Mr. Hauck holds a BA from Macalester College, a BSEE from South Dakota State University, and a MSEE from the University of Minnesota.

Doug Johnson

CTO, Director

Co-founder Doug Johnson has 30 years of experience in R&D and business development. He began his career with Honeywell’s Computer Sciences Research Center in 1994, developing the company’s first expert systems. He left Honeywell to start a software business prior to joining 3M in 1991.

At 3M he most recently served a senior product development specialist. While there he invented an innovative composite power cable upon which he holds 15 patents. He assumed responsibility on the management team to build a global business for this product, which has been featured in 3M’s annual reports. Mr. Johnson’s product was recognized by an R&D 100 award as one of the 100 most innovative and significant research and development advances in the United States. Mr. Johnson recently left 3M to join Mr. Hauck at Lite Run full time.

Mr. Johnson graduated with honors with a BA degree from the University of Minnesota; studied economics under PhD program fellowship at Cornell University; and additionally studied physics at the University of Minnesota.

Jerry Hu

Director

Jerry Hu has 30 years of professional experience both as a practicing physician and in medical system sales management. He started his career as a physician and practiced in cardiology in China and was a visiting fellow in University of Massachusetts Medical Center. Since entering the medical system business, he has been worked for several start-up medical system companies, such as Asian & International Business Director and Vice-President in Prucka Engineering, Endocardial Solutions, Stereotaxis, Ablation Frontiers, Atritech, Magnetecs, and currently he is at Veran Medical Technologies Inc.

Most of these companies have been acquired by major medical system companies, such as GE Medical, St. Jude Medical, Medtronic and Boston Scientific, due to cutting-edge novel technologies and promising business potential. While Mr. Hu is a medical technology visionary, he has deep experience in new product launch and market development with a track record in business development.

Mr. Hu graduated from medical school in China and completed the Executive Development Program in Columbia University Graduate School of Business in 2002.

Mark Johnson

Co-Founder

Mark Johnson started a career in the precision machining trade 27 years ago. Since then he has designed and built custom machines and product prototypes for many different industries. Mr. Johnson owned and operated a precision machining company for 6 years before going to work for Endocardial Solutions (ESI) in 1999. At ESI he supported the manufacturing of the EnSite catheter and R&D projects.

Mr. Johnson was co-inventor of a sophisticated robotic catheter system, and after St. Jude Medical acquired ESI in 2004, he joined a group responsible for developing it into a product. Mr. Johnson has spent the last six years developing and building prototypes of Lite Run's unique gait training system. Mark holds 6 US patents.
