A Residential Contractor Built Around Clear Project Execution

Core Service Professionals LLC does business as Decker Service Professionals. We serve homeowners throughout the Kansas City area with remodeling, decks, painting, windows, and broader home improvement work.

Our projects range from focused repairs and replacements to larger multi-trade remodeling and outdoor-living projects. The goal is to define the work clearly, coordinate the people and materials involved, and manage field conditions as they arise.

Clear Scope. Coordinated Work. Straightforward Communication.

  1. Define the Work Clearly

    Develop a written scope that explains the planned work, included surfaces or areas, and known project conditions before construction begins.

  2. Coordinate the Project

    Organize crews, subcontractors, materials, selections, and sequencing so the different parts of the project work together.

  3. Communicate Field Conditions

    When concealed damage, framing issues, field-fit conditions, or homeowner-requested changes affect the work, explain what was found and how it changes the project before proceeding.

  4. Finish With a Walkthrough

    Review completed work with the homeowner and address applicable punch-list items before closeout.

The People Behind Decker

Decker projects are coordinated by a small team responsible for estimating, sales, production, and office support.
Guy Holt, Owner / General Manager at Decker Service Professionals

Guy Holt

Owner / General Manager

Guy brings 40 years of construction and home improvement experience to Decker Service Professionals and has led the company since 2018. As a licensed Class C builder, he oversees estimating, company standards, financial decisions, and major project planning while helping guide the team responsible for sales, scheduling, customer communication, and field execution.

After four decades in the industry, Guy believes trust starts with telling the truth. Decker was founded in part to challenge the poor reputation contractors can have by emphasizing transparency, clear expectations, quality, and accountability. He especially enjoys the design and problem-solving side of construction—working through project details, finding practical solutions, and helping homeowners achieve the result they had in mind.

Outside of work, Guy enjoys spending time with his daughter and son, gardening, and caring for animals.

Senior Project Lead - Production Systems & Quality Control

Dustin brings more than 20 years of experience across construction, remodeling, home improvement, field operations, and related trades. He has been with Decker Service Professionals since March 2021 and has spent more than five years helping manage projects, crews, field conditions, and production standards.

In his current role, Dustin supports production systems across Decker’s projects, including labor tracking, estimated-versus-actual reporting, procedure compliance, field training, and identifying ways to improve efficiency and estimating accuracy. He also helps maintain production and quality standards and may lead assigned projects when needed.

Dustin’s broad hands-on background helps him troubleshoot field conditions and understand how different parts of a project come together. His experience includes remodeling, granite and stone fabrication and installation, low-voltage and satellite work, crew leadership, and project management.

He places a strong emphasis on preparation, clear communication, safety, and catching problems early. His goal is to help crews work efficiently, maintain consistent standards, and keep projects moving toward a dependable finished result.

Office Administration

Lisa brings more than 20 years of combined professional experience to Decker Service Professionals, including approximately 10 years in the construction industry and 10 years working in the legal field. She has been with Decker for five years and plays a central role in keeping the office, customers, and project team organized.

Lisa manages day-to-day office operations, customer communication, recordkeeping, scheduling support, and the administrative details that help projects move from the initial conversation through completion. She works closely with both customers and the field team to help keep information accurate, questions answered, and project details organized.

Her background in the legal field strengthened her attention to detail, documentation, organization, and ability to manage important information accurately. Combined with her construction experience, that gives her a practical understanding of both the paperwork behind a project and the communication needed to keep customers and crews on the same page.

Lisa places a strong emphasis on clear communication, follow-through, and customer service. She understands that homeowners often have questions throughout a project, and she works to make sure they know who to contact, what is happening next, and that their concerns are addressed promptly.

Outside of work, Lisa enjoys gardening, spending time with her family and grandkids, decorating, and creative projects around the home.

Project Lead & Scheduling

Charles brings nearly three decades of construction and home-improvement experience to Decker Service Professionals, having worked in the trades since he was 16. His background across multiple areas of construction gives him a practical understanding of how each phase of a project fits together and what needs to happen to keep the work moving properly.

Since joining Decker in March 2026, Charles has taken an active role in project scheduling, customer communication, jobsite leadership, and coordinating work in the field. He helps make sure projects are ready to move forward, crews understand the plan, and customers know what to expect as work progresses.

Charles believes good planning and consistent communication are critical to a successful project. He pays close attention to both the quality of the finished work and the decisions that affect the customer’s cost.

His standard for the crews is simple: “If it’s not good enough for your mother’s house, it’s not good enough on my jobsite.”

Since joining Decker in 2026, he has focused on meeting with homeowners, understanding what they want to accomplish, developing project scopes, and helping customers understand the options and next steps for their project.

As part of Decker’s sales and estimating team, Jacob works closely with homeowners during the early stages of a project. He pays particular attention to the details discussed during appointments so the proposal accurately reflects the planned work and the customer’s expectations.

Jacob’s background in customer service, including years of bartending, helped him develop strong people skills and an ability to communicate comfortably with a wide range of customers. He enjoys getting to know homeowners, asking the right questions, and helping turn an initial conversation into a clearly defined project.

For Jacob, one of the most rewarding parts of the job is meeting new customers and building relationships that lead not just to a successful project, but to homeowners who choose Decker again for future work.
