Valued Partnerships ~ We believe in creating relationships based on trust and honesty and have genuine friendships with our partners that go beyond the business relationship. We come alongside our partners to fight through the trials and to celebrate the successes together as a team.

Product Support ~ We will continue to add and shape our product mix based on the needs and demands of our customers. We are known for the ability to source necessary products, while getting the competitive pricing and quality that our customers come to expect from us.

Warner Tech-care History: Where We Come From & Where We're Headed

It all started in 1984 when Warner Industrial Supply turned its focus to customers in the hearing healthcare industry. We found a niche in the market by providing hearing products and accessories to large manufacturers like Starkey Hearing Technologies and Dahlberg Electronics. We quickly found success in this rapidly growing industry and in 1992, formed a division called Warner Technologies, focused solely on sales for manufacturing and hearing healthcare supplies.

The high demand for these products led to the conception and launch of our own Tech-care line branded products in 1995. We’ve designed these quality products to provide a more competitive price to large name brand products, as well as fill any product gaps our customers may have.

In 2003, Teresa Nelson, founder and CEO, offered our parent company an opportunity to sell her the hearing division. Once accepted, Warner Tech-care Products, Inc. was born. Warner Tech-care continued to thrive under its new identity and launched our first website in 2006, giving customers more access to products, service and information. That year, we continued to grow our product offerings by adding Ear-guard™ Hearing Protection and Quick-pro™ Instant Earmold material, both staples in our product line today.

Ten years later, Nelson retired as President of Warner Tech-care Products and sold the company to our current President, Lee Heidenreich and Pathfinder LLC (a financial partner with a passion for the hearing industry).

Under this new leadership, we’ve added two new companies through acquisition. The addition of Hal-Hen, a wholesale distributor with a 70-year reputation of servicing the hearing aid market, resulted in a significant increase in the number of products and services we now offer our customers. Secondarily, adding Hearing Technologies International to our portfolio has drastically increased international sourcing capabilities.

By March of 2019, we had outgrown our Roseville, MN location and made the move just a few miles north to our current home in Arden Hills, MN. The space has plenty of room for us to grow and continue to improve in a way that suits our customers.

Speaking of growing, in September 2025 we acquired the Audiology Supplies business from Westone Laboratories, a long time competitor and partner in the industry. Combining our businesses gives audiologists and hearing instrument speciaists a one-stop-shop for impression material, tubing, office supplies and much more.

We’ve undergone a lot of changes throughout the history of the company, but our sound reputation, enduring dedication, and unmatched service has remained constant. We continue to serve those we love in an industry we care for deeply.

We are dedicated to equipping the hearing healthcare industry with the quality supplies and support needed to prevent and treat hearing loss worldwide.
