The Partners

Corey Callery,
Partner/President

Corey Callery has worked in the office furniture installation business for 37 years and brings his extensive experience to every project. He has managed projects large and small for a variety of clients across many business sectors. Corey has experience with all of the major office furniture manufacturers and systems.
Much of his career was spent working for furniture installation companies where he developed an extensive network of client, business, and personal relationships. During this time, Corey always felt he could better serve his clients by having his own business where his values and beliefs could be the bedrock of those relationships. With Corey’s vision Trinity 3in1 Services, Inc. was formed and our motto, “Office Furniture Installation with Integrity”, was developed and is the basis of how we approach every client project.

Jared Callery,
Partner/Senior Vice President of Operations

Jared has learned the furniture installation business from the bottom up. He started as a furniture installer and progressed to supervising installation crews. As Jared gained more experience and knowledge, his responsibilities expanded to managing progressively larger projects and crews, coordinating furniture deliveries, developing schedules, and providing overall project management duties. Jared has 16 years of experience in the furniture installation business, is a partner in the company, and currently serves as the Senior Vice President of Operations. In this capacity, he not only has responsibilities as an owner, but also assists Corey in managing client relationships, schedules, production, and personnel assignments for all active projects.

Our Foundation

As a faith-based company we strive to conduct ourselves in a manner that glorifies God in every way.  We desire to be faithful stewards of the resources the Lord has blessed us with and show the love of Christ to everyone we encounter.

We have been blessed by the Lord and want to be a blessing to our clients.  Our mission is to be our client’s system furniture installer of choice by providing honest, valued, and competitive services.

I had my first move / installation with Trinity 3in1 services this week and they were fantastic. The customer even called to give a review of how well they were doing and how professional Corey was on the job site.

This was a last minute move that Corey could fit into his schedule due to his client having to cancel this week. As the owner he even took the time to complete a site visit just so he could accurately provide a quote.

Trinity 3-in-1 has been a great asset for all my projects within Liberty Mutual.  They know what they are doing, are respectful, courteous, pro- active and a hard working group of men and women. 

 They are on time and reply with responses in a timely manner.  When asked to do a task, especially one that involves a change, there is never a complaint – they just do it.

Their work ethic is superb.  I would highly recommend Trinity for any moves or furniture installs; they are excellent people to work with.

 Trinity 3in1 Services provides excellent customer service! No task is too large or small.

Trinity has provided a staff that is professional, courteous, and highly motivated to complete the job needed regardless of any “roadblocks” that come their way!

They are extremely adaptable to changes in Project Management scope.
