Mackenzie Seiffert


“My grandfather taught me about how to treat clients. When you hire us, you’re getting the values and the trust that come with the company. It’s not just a business arrangement.”

Mackenzie Seiffert has literally grown up with the company founded by her grandfather, John Rhodey. She knows Rhodey’s team well — and many of our clients, too — because she began working in the business part-time at age 16.

Mackenzie joined her mother, Pam Duffy, in the family company as a full-time employee in 2007. As vice president, she works to keep client projects organized, coordinates with subcontractors and suppliers, documents key meetings and facilitates clear communication among the team and clients. Mackenzie’s work is instrumental in enabling project managers to focus on delivering great work that surpasses our clients’ expectations.

With a Bachelor’s degree from Benedictine College and an MBA from Lindenwood University, Mackenzie brings strong organizational and communications skills, the ability to work under deadlines, and strategic business training to her role at Rhodey. In 2019, she became a Certified Health Care Physical Environment Worker.

More important, she continues her grandfather’s values and vision for the company. As part of the family whose name is on the door, Mackenzie takes great personal pride in everything she does. She grew up embracing the company’s values as her own, and she learned from both John and Pam the importance of building relationships based on trust and doing whatever it takes to make our clients happy.

“I try to make the client’s project run as smoothly as possible by being attentive to every detail. I try to make the process fun and enjoyable; if I keep them happy, then I know we’ll get another opportunity to work on their next project.”

As vice president, Jim Feldmann takes the lead on Rhodey’s healthcare-related construction business. His 20+ years of experience give him deep knowledge of medical facilities and a real sensitivity to the nature of these jobs. “I work with each institution’s facility and design team to develop a plan to keep the patients safe and the staff functioning,” he says.

Jim guides projects through the design development phase, providing valuable insights on construction feasibility and ensuring that renovation plans work with existing conditions and systems. He outlines each phase of construction (often involving simultaneous projects) to meet schedule and budget requirements while also respecting patient care.

With his strong communication skills, Jim maintains frequent contact with the client, subcontractors and with his right-hand man on the job: the superintendent. “Communication is key to being successful in this business. There are always issues that arise from field changes, conflicts in existing conditions or delayed lead times. As long as we communicate with each other, most situations resolve themselves easily.”

He earned his BS/BA degree in construction management with a minor in business from Southern Illinois University – Edwardsville. He also received his Healthcare Contractor’s Certificate training from the American Society for Healthcare Engineering.

At Rhodey, Jim appreciates that the organization is built on mutual trust and respect for employees’ knowledge and experience. Pam Duffy, he says, encourages and enables her team to make their own well-informed decisions.

Jim Imperiale


“I came to work with Rhodey because of the Firm’s reputation for quality and integrity. You just don’t find that every day.”

When he joined the Rhodey team, Jim Imperiale, LEED AP, DBIA, was already an industry veteran with more than 30 years of work in civil construction. Jim has experience in nearly every aspect of the business, from field work to management to business ownership, and he brings a high degree of integrity and fairness to his professional relationships. As a vice president in the company’s general construction and subcontractor services divisions, Jim oversees each step of the building process to successfully realize the customer’s vision.

Jim’s hands-on approach to each project begins with helping to determine specs and estimating. From there, he guides every aspect of the job, including field supervision, scheduling, client service, architect and engineer relationships, contracts and change orders, and preparing warranty packages as part of the closing phase. Jim takes a proactive and organized approach to project management, and he has an excellent track record of delivering projects on time and on budget.

After attending Fontbonne University as a business administration major, Jim owned his own concrete restoration company, where he directed projects at a high level and also managed
day-to-day issues.

Jim’s experience as a subcontractor working with Rhodey introduced him first-hand to the exceptional way that our company values our suppliers and subcontractors as well as our clients. Jim recognized that these relationships — built on partnership and trust — make our company stand apart. “I liked the culture of the company from the contacts I had made there,” he says.
