About Us

How We Started

Thentic was formerly known as Stemle and Associates. Founded in 1993 by the Stemle family, the company has a long-established history of being a trusted furniture  manufacturing provider. Steve Stemle’s mantra was that an effective salesperson is always selling, always in the field, and always pushing products. This mantra became foundational for the uniquely dedicated customer service the company provided in comparison to other manufacturers. Stemle had created a new level of value for dealers and design firms.

Where We Are Now

In 2020, the company was purchased by Justin Wendholt and since then has become Thentic.

Before owning Thentic, Justin worked in the healthcare industry. He experienced first-hand the impact that designed spaces have on the comfort and emotions of people, especially in vulnerable situations. Justin worked in sales in the past and wanted to find his way back to it. The combination of his experiences naturally led him to purchasing the company, where he found a business that lived up to his values of service and sales.

Now, Justin and his team have the privilege of helping designers create functional and attractive spaces that foster better experiences for the people who inhabit them.


“Since Justin has taken over Thentic, Office Interiors has been pleased with how everything has gone from the quotation process, design, order entry, and deliverables. They always go above and beyond to help us look good in front of our clients. Their product mix has grown and given them the ability to meet all aspects of a building.”
