Glenn J. Butler – President & CEO

Glenn Butler has more than 40 years’ experience in civilian hospital, military, NASA and commercial diving hyperbaric operations. He has developed and / or operated over 20 major hospital-based Hyperbaric Medicine programs internationally. 

Mr. Butler was the principle consultant when LST was sole-sourced by NASA-Johnson Space Center to engineer zero gravity simulation breathing systems and develop new oxygen safety standards for the astronaut training program designed to support the Hubbell Space Telescope emergency repair mission. 

Butler and LST were also sole-sourced to provide emergency medical support and hyperbaric chamber operations and decompression tables to the MTA East Side Access Tunnel Project. LST directed 283 pressure interventions totaling over 44 days under pressure at pressures to 34 PSIG.

Glenn Butler (CHT #-012) was a founding member of the National Board Certification for Hyperbaric Technologists and is a member of the NFPA-99 and UHMS Hyperbaric Safety Committees.

Patrick McCabe - Chief Financial Officer

Patrick McCabe has a unique financial / business background in the management and operation of hospital-based Wound Care and Hyperbaric Medicine Centers. Prior to joining LST in 2003, Mr. McCabe spent thirty (30) years as the V.P. of Finance of a large Marine Construction / Diving Firm with an operating budget of over 20 million USD. Mr. McCabe has financed, insured and controlled payrolls for multiple Deep Sea Diving and Hyperbaric Chamber Saturation Diving Systems, Submarines and Ships including the Major Hyperbaric Medicine Centers – North American Hyperbaric Center in New York and the North Sea Hyperbaric Centre in Aberdeen, Scotland.

Over the last eight years, Patrick has been instrumental in helping to direct LST controlled growth to 9+ major Contract Companies and the transition into a major Healthcare provider Company that is reviewed by a CPA firm. 

Jorge Beale - Controller

Mr. Beale has more than 14 years of professional experience in hospital-based Hyperbaric Medicine and Wound Care Management and Installations. As Controller for the Life Support Technologies group his duties including Billing Coordination, IT management, Center Management and various other tasks. Mr. Beale is an Iona College Hagan School of Business Graduate in Business Administration and is New York State Life and Health Insurance Licensed.

ael W. Allen – Senior Vice President Operations & Safety
Mike Allen has over 40 years of experience in the hyperbaric field including air, mixed-gas and saturation deep-diving operations around the world and diving equipment development.  Mike is internationally known for his contribution to diving and hyperbaric safety and currently serves on the governing committees of the two primary hyperbaric safety standards here is the United States, (see below).  In 1982, Mr. Allen took over the project management of DSV STENA-SEASPREAD operating in the Thistle Field in the British Sector of the North Sea. In addition to the daily management of the vessel, this position included day-to-day support of offshore operational activities, p lanning and all other requirements related to the execution of the contract.  He is currently Senior Vice president – Operations and Safety for Life Support Technologies group.

Since 2005 Mike has been a principal member of the NFPA 99 Standard for HealthCare Facilities technical committees for Hyperbaric and Hypobaric Facilities. He has been a member of the ASME Safety Standard for Pressure Vessels for Human Occupancy (ASME PVHO) committee since 2000. In addition to being a member of the main committee, Mike is currently active on the following sub-committees.

  • General Requirements (PVHO 1) – Vice Chair
  • Design & Piping (PVHO 1)
  • Diving Systems (PVHO 1)
  • Medical Systems (PVHO 1) – Chairman
  • Piping Systems (PVHO 1)
  • Viewports (PVHO 1)
  • Post-Construction (PVHO 2)
  • TG Tunneling – Chair (recently formed) 

David Kenyon - DCAP Engineer

A senior mechanical and systems engineer with over 45 years engineering/scientific experience.  He received his Bachelor of Mechanical Engineering (BSME) Degree in 1967 from Rensselaer Polytechnic Institute.

Dave Kenyon together with Dr. Bill Hamilton (now deceased), has developed many types of decompression procedures for a wide variety of diving and exposures to pressure, ranging from submarine free ascent to space travel to deep commercial diving, including detailed instructions for treatment of decompression sickness. This work has evolved into a comprehensive computer program DCAP, which has been acquired by the British, Swedish, Japanese, Finnish, Israeli, Italian, and U.S. navies, DCIEM, the German GKSS facility, the Japanese lab JAMSTEC, hyperbaric treatment facilities, and commercial companies. DCAP and related programs have provided decompression tables used by such as NOAA, NASA, Norwegian Underwater Institute, U.S. Navy labs, and Karolinska, Sweden.

His work with decompression tables, physiological effects of gases, and methods of managing exposure to oxygen were instrumental in the origination and development of the new field of “technical diving.” He has helped apply this to the unique decompression and operational problems of deep cave diving, specifically with O2-He-N2 trimix, on several record-setting cave exploration dives with scuba over the depth range of 60 to beyond 250 msw. He has helped in the development and assessment of several diver-carried decompression computers, and with colleague Bill Hamilton is presently completing a new and original dive computer, DCAP-X, that incorporates the DCAP computational program.

Dave Kenyon together with Bill Hamilton were a pioneer in the development and later operational application of nitrogen-oxygen (nitrox) saturation-excursion procedures, including those in the NOAA diving manual as well as NOAA’s Repex procedures for repetitive excursion diving, which also include a serendipitous but now widely applicable algorithm for managing long term exposure to oxygen. The team at Hamilton Research has assisted the U.S. Navy in operational application of Repex techniques. He has worked on development of rebreathers, including especially rebreather decompression procedures and integrated computers, safety practices, and instruction materials, and he has carried out training and intensive manned testing. Hamilton Research completed working on the Brightwater West tunneling project for King County, Washington, where he is responsible for decompression tables including those with trimix, and other aspects of physiological safety. Hamilton Research has recently completed a comprehensive decompression table system for interventions from 18 to 42 psi on air, with abort decompression procedures with O2 and with air only.

Mark Chipps – Corporate Compliance Officer
    Mark Chipps has been working in the healthcare field since the mid 1990’s and has extensive experience with both multiplace & monoplace hyperbaric facilities.  There he has held positions as Unit Supervisor & Safety Director.  Prior to becoming involved with clinical hyperbaric activities, he worked as an EMT-Critical Care and diver for an underwater search and rescue team.

    Mark led the LST Hyperbaric Tunneling Support group in helping to complete the MTA East-Side Access Tunnel Project connecting the Long Island Railroad with Grand Central Station in Manhattan. The LST group provided Hamilton / Kenyon DCAP Decompression Tables, Paramedics and Tunnel Boring Machine Hyperbaric Chamber operations.
