Innovative Sterilization Technologies (IST), headquartered at 7625 Paragon Rd., Suite A in Dayton, has announced the appointment of Tim Tzimas as its new President and Chief Executive Officer, effective January 1, 2026, marking a new chapter for the company as it continues to reshape sterilization efficiency and medical device organization.

Tzimas brings more than 25 years of leadership experience in the orthopedic, neurosurgical, and medical technology sectors, with a career focused on sales management, operations, and organizational development in regulated healthcare markets.
Most recently, Tzimas served as joint reconstruction sales manager for the New York Metro Branch at Stryker, where he led one of the company’s largest U.S. territories. There, he managed strategic sales, robotic system utilization, and oversaw a team of more than 25 sales, clinical, and operational professionals.
Tzimas steps into IST’s top seat at a time where cases are rapidly transitioning from inpatient to outpatient facilities, causing pressure to do more with less—higher case volumes, tighter margins, and growing regulatory demands. IST’s leadership believes Tzimas’s experience and perspective in the power of consolidating trays, enhancing workflows, and maximizing efficiencies, position the company to meet those challenges head-on while continuing to expand adoption of its flagship ONE TRAY® system.
“Sterilization has long been treated as a necessary behind the scenes function, and in many ways the industry is still operating on outdated assumptions,” Tzimas said. “I want to help IST dispel existing dogma and change the perception in the market about how to best manage surgical instrument sterilization and containment.”
Under Tzimas’ leadership, IST plans to sharpen its focus on helping inpatient and outpatient facilities scale efficiently while maintaining the highest standards of safety and compliance. Wider adoption of ONE TRAY® and EZ-TRAX™ will elevate surgical workflow at facilities challenged by limited space, excessive cost, disconnect in instrument delivery and processing of instrumentation.
“My goal is to help surgical facilities sustain increased volumes and long-term success,” Tzimas said. “When teams are less burdened by unnecessary steps and inefficiencies, they can focus on what matters most—patient care and operational excellence.”
Tzimas sees the opportunity to shift industry language and thinking altogether, with The Total Solution, ONE TRAY®, E-Z TRAX™, and ONE CART ™, not just as another option, but as the standard.
“I want professionals in that space to simply say, ‘Just ONE TRAY® it,’” he added. “That’s when you know you’ve changed the conversation.”
IST officials said Tzimas’ appointment reflects the company’s commitment to innovation, education, and leadership in sterile processing at a time of rapid change. With demand for outpatient procedures continuing to rise, the company expects his vision to guide IST’s next phase of growth while reinforcing its mission to simplify sterilization without compromising quality.
Innovative Sterilization Technologies (IST) announced has also announced that ONE TRAY® sterilization container has received a second clearance from the U.S. Food and Drug Administration (FDA), significantly expanding its use across hospital and surgical facility workflows.
ONE TRAY®’s original clearance in 2006 (IFU K052567*) included sterilization at 270°F (132°C), Exposure Time 4 minutes, Cycle Dry Time Not Required and validated to maintain the sterility of the contents for up to a 48-hour storage period.
ONE TRAY®s NEW additional clearance in 2025 (IFU K250029**) maintains the same validated sterilization parameters – 270°F (132°C), Exposure Time 4 minutes, but with a 365 day event related shelf life/storage period with a 15-minute minimum dry time.

When introduced in 2006, ONE TRAY® represented a new approach to sealed sterilization container technology. Now, according to Barbara Ann Harmer MHA, BSN, RN, Vice President of Clinical Services at IST, the expanded storage window provides facilities with even more operational flexibility.
“The additional storage time gives the surgical department an alternative when unforeseen problems arise in the operating room,” Harmer said. “Those surgical delays often ripple far beyond the OR.”
“When patients arrive for surgery, they’ve already prepared, food and medications withheld, family schedules arranged, anxiety managed,” she said. “If the schedule is seriously disrupted, so are their lives. ONE TRAY® provides two solutions to keep everything on track. If the instrumentation is available, we are the fastest option to maintaining the schedule.”
“With the rising cost of healthcare, everyone is being asked to do more with less,” President and CEO of IST Tim Tzimas said. “The dual FDA clearances improve efficiency across the entire chain of custody in the sterilization process – an increasingly important factor as healthcare systems face mounting costs and staffing pressures. It truly offers a total solution and total flexibility to respond to clinical urgency, optimize inventory, and standardize sterilization processes using a single, reusable sealed container platform.”
