Meet the Team


Bob Hillebrandt, owner


  • Bachelor of Science in Mechanical Engineering, University of Wyoming
  • Organizations: IIAR, Mechanical Contractors Association of Omaha

Bob’s vision for LoTemp Equipment Company came into focus in 1979 when he started the company in an empty north Omaha warehouse. “I wanted to take my expertise in the engineering and refrigeration fields and help companies grow.” The company has grown from just having him and one steamfitter to having multiple installation crews, a fully staffed service department, and a PSM department. Even with all the growth, Bob’s philosophy has been passed down to the next generation of the LoTemp team. “Be honest, treat the customer right, and offer real solutions.”

Bob is enjoying spending more time with his wife, Teresa, his five children and their spouses, and his 14 grandchildren. He also carves out time to make sure his golf game does not turn rusty.

Nicky Rainbolt, owner


  • Bachelor of Science Degree, Mechanical Engineering, Iowa State University
  • University of Wisconsin-Madison Ammonia Refrigeration courses on Engineering Safety Relief Systems, Principals and Practices of Mechanical Integrity for Industrial Refrigeration Systems & Nondestructive Testing Methods for Mechanical Integrity; Kansas State Industrial Refrigeration Workshop
  • Professional Engineer: Nebraska, Iowa, Kansas, Missouri
  • Organizations: IIAR, member of Education Committee; Mechanical Contractors Association of Omaha

Nicky enjoys leading LoTemp’s Construction & Engineering department to find solutions to a customer’s refrigeration needs. “There’s no better feeling than participating in a process that results in the customer meeting or exceeding its business objectives. When that happens, I get to celebrate the customer’s success.” Nicky also assists customers in their PSM needs.

When Nicky is not problem-solving for LoTemp customers, she is hiking U.S. mountain ranges with her husband Andrew and their three children.

Patrick Hillebrandt, owner


  • Vilter Safety & Education School, Local 464 Steamfitter Apprenticeship program
  • RETA

If it involves ammonia refrigeration, Patrick can handle it. From running installation projects, to troubleshooting compressor issues, to dealing with rogue PLCs, Patrick has the expertise and ability to help the customer through it. “It’s important for me to visualize the entire LoTemp-customer process – from estimating the job to installing the new equipment, to observing the end-result.”

To stay current with industry changes, Patrick regularly attends continuing education classes through industry sponsors and RETA.

When Patrick gets a break from responding to the needs of LoTemp customers, he dedicates his available time to his wife Tracey and his two children.  He’s a sports fan, and awaits the day when his beloved Miami Dolphins will be a contender again.

John Hillebrandt, owner


  • Creighton University School of Law, Juris Doctor
  • St. Louis University, Bachelor of Arts, English
  • University of Wisconsin-Madison Ammonia Refrigeration courses on System Safety, Process Hazard Analysis, Safety Management Audits
  • IIAR, RETA, Mechanical Contractors Association of Omaha (MCAO) Board Member and Vacation Fund Trustee

Before the LoTemp engineer and design team have finished their jobs, John and his service team are already in their starting positions. “LoTemp’s service team has to identify a customer’s needs and develop a plan to satisfy that need with accuracy.” Service is a rapid-response and precision activity. That’s where John’s analytical skills come in.

His customized service agreements are absent of fluff and heavy on customer priorities so that PMs get done on time, done correctly, and are documented.

John also takes pride in developing plant’s mechanical integrity programs, performing PSM compliance audits, and running PHAs.

John and his wife Emily keep busy with their three boys. When he’s not chasing them around, he is usually coaching one of their teams or taking them golfing.

Pat Rainbolt


  • Bachelor of Science, Construction Management, University of Nebraska-Lincoln
  • University of Wisconsin-Madison Ammonia Refrigeration courses on Engineering Safety Relief Systems, Design of Ammonia Refrigeration Systems for Peak Performance Efficiency
  • Organizations: IIAR; Mechanical Contractors Association of Omaha; RETA

Pat subscribes to the theory “You can’t do it alone.” He likes to be involved in a collaborative, hands-on process with the LoTemp team and its customers. “LoTemp and its customers experience success because they forge partnerships.”

For Pat, solidifying partnerships with LoTemp customers is something that must occur sooner rather than later in the relationship. “I’m with the customer at the very beginning – from the idea or vision to the final refrigeration system that functions the way it was designed. You won’t see a satisfied smile on my face until I first see a similar smile on the customer’s face.”

Off-hour satisfaction for Pat is spending time with his wife Ashley and their two sons.

Andrew Bayly


  • Bachelor of Science, Construction Management, University of Nebraska-Lincoln
  • University of Wisconsin-Madison Ammonia Refrigeration courses on Engineering Safety Relief Systems, Design of Ammonia Refrigeration Systems for Peak Performance Efficiency
  • IIAR, Mechanical Contractors of Omaha (MCAO) Golf Committee, Student Recruitment committee
  • OSHA 10 hour and 30 hour

Andrew wants to solve customers’ headaches, not cause them. They should be able to tell me what they want to accomplish, and we can take it from there. From conception and budgeting, to construction and project execution, we want to provide quality service that doesn’t burden our customer’s workload.”

Andrew and his wife, Emma, have four children that includes a set of twins. When he isn’t spending time with them, he enjoys fishing, preparing for the next hunting season, and competitive archery competitions.

Molly Freyer


  • Bachelor of Science Degree, Mechanical Engineering, Iowa State University
  • Masters of Business Administration (MBA) from University of Nebraska-Lincoln
  • Project Manager Professional (PMP) since 2014
  • Multiple leadership roles in the manufacturing industry before joining LoTemp

Molly’s extensive background in engineering and manufacturing, coupled with her Masters of Business Administration, allows her to deliver a refrigeration solution that is safe, reliable, and addresses the customer’s business needs. She fits right in with the LoTemp team. “I think LoTemp’s strength is we have not only the talent, but also integrity, to possibly solve a problem with a simple, affordable solution instead of trying to sell them a whole new plant.”

Molly, her husband Matt, and her two children are avid travelers, mountain bikers, and hikers.

Pat McCoy


  • Vilter Safety & Education School
  • RETA

Pat knows something about ammonia refrigeration systems.  He’s been working on them since 1975.  Pat is a “learner.” Over his many years with LoTemp, he has taken advantage of most Vilter service and safety education opportunities. “There’s always something new to learn, and the new information I acquire is usually in the best interest of the customer. The more up-to-date I am, the better I’m able to troubleshoot for customers.”

Along with sharing his free time with his wife Jane and their son, Pat likes to golf and mastermind home projects.

Michael Woosley


  • RETA – PSM/RMP, Refrigeration 1, Industrial Refrigeration 1
  • FEMA – Incident Command System
  • Industrial Maintenance since 1997
  • Industrial refrigeration maintenance supervisor for 9 years
  • PSM supervisor for 9 years

Michael knows safety and PSM because he lived it for over 9 years at his former job. He successfully ran an active, living PSM program that went through countless internal and external audits. He brought this extensive experience over to LoTemp and help other customers with their programs. Whether it’s developing a program from scratch, performing PHAs, running a Compliance Audit, or performing a Mechanical Integrity Audit, Michael brings his years of experience to make sure the customer is taken care of. “Exceeding our customers’ expectations is my goal. We pride ourselves on professionalism and efficiency.”

Michael enjoys spending time with his wife and working on muscle cars, going to the shooting range, and trail riding.

Connor McNeil


  • Factory training on parts and valve operation
  • Parts acquisition and coordination since 2014

When you need ammonia refrigeration parts and need them fast, Connor is your guy.

Whether it’s an obscure part or a regular valve off the shelf, Connor responds to each parts request to the best of his ability. “There is something gratifying about tracking down an unusual part and getting it to the customer on time.” His dedication and performance help build trust and loyalty. That’s why customers have come to rely on him for all of their ammonia refrigeration parts needs.

When Connor isn’t taking care of customers’ parts requests, he likes to assemble and paint models, hike, read, and take his nephew to the zoo.

Kathy Hillebrandt


Every successful business has that hidden person who makes sure the levers and gears keep turning. Kathy is that person for LoTemp.

Kathy gets to observe LoTemp leadership, engineers and servicemen strive to deliver a quality product to their customers. Because she is often on the receiving end of familiar customer comments, she is able to summarize their opinion of LoTemp: “Customers notice LoTemp’s values – and the company’s supportive and cooperative employees.”

Kathy and her husband Pat like to spend their leisure time with their seven children and 17 grandchildren.
