She keeps things moving with a sharp eye for detail and a communication style that's clear without being cold.

    Mayra M.

    Medical Billing & Support Specialist

    Specialties

    Mayra started in Customer Support and worked her way into the Medical Billing Department, and that path matters. She understands both sides of the operation, what clients experience on the front end and what it takes to keep billing accurate and compliant on the back end. That dual perspective makes her more effective at her job. She doesn't just process billing; she understands the context behind it. She's also been hands-on in rolling out new software systems and supporting operational improvements across departments, the kind of work that doesn't always get recognized but keeps everything else functioning.

    Hobbies & Interests

    Outside of work, Mayra enjoys crocheting and spending time with friends and family.

    Vicki R.

    Fulfillment & Distribution Coordinator

    Specialties

    Vicki started in Data Entry and has grown into one of the most operationally experienced people on the team. That kind of progression is earned, not given, and it shows in how she works. As Fulfillment & Distribution Coordinator, she oversees the full arc of an order: from entry through warehouse coordination, shipping, and final delivery. She knows where bottlenecks happen, how to prevent them, and what it takes to keep accuracy and timeliness consistent when volume is high and the margin for error is low.

    Hobbies & Interests

    Outside of work, Vicki is active in her community and takes on home renovation projects with her husband, which says something about how she approaches a challenge.

    MJ F.

    Director of Operations & Compliance

    Specialties

    MJ runs the operations side of EMX Health, which in practice means she's involved in almost everything. Compliance, administration, fulfillment coordination, training, safety, internal process management; if it affects how the company functions day to day, it crosses her desk. What that kind of role actually requires is someone who can hold a lot of moving parts without letting any of them slip. MJ brings that through a strong focus on accountability, process discipline, and the kind of attention to detail that keeps a healthcare distribution company operating at the standard it needs to. She's also the person responsible for ensuring EMX Health meets regulatory and accreditation requirements, which isn't just a compliance checkbox; it's what makes the operation trustworthy.

    Hobbies & Interests

    Outside of work, MJ enjoys cooking, spending time with family and friends, and browsing local farmers markets for fresh ingredients and new ideas.

    Derek Zimmer

    CEO & President

    Specialties

    Derek Zimmer has spent his career building service operations people can count on. He started at 19 in delivery & logistics and learned early that in a service business, reliability is everything. Over the years, Derek grew that foundation into a full operating system, managing scheduling, inventory, vendor relationships and last mile delivery across multi-department teams. Every part of that experience was shaped by a simple standard: if someone is depending on you, you do not let them down. That is the standard he brings to EMX Health. In medical supply fulfillment, the stakes are real. Patients need the right products on time. Caregivers need a partner they can trust. Referral sources need to know that when they send someone to EMX Health, that person will be taken care of. Derek built EMX Health around that responsibility, with consistent processes, clear communication and a team that understands what is at stake for the people on the other end of every order.

What They’re Saying About Us

As a medical parent, the last thing we need is the added stress of searching for the equipment and supplies our child needs to have the best possible quality of life. EMX Health is by far the best DME experience we’ve had. Their customer service is exceptional, and their team went above and beyond to help us find the right vendor for our needs. They also provided incredible support throughout the insurance authorization process, making what is often a frustrating and overwhelming experience much more manageable. We are incredibly grateful for their hard work, dedication, and persistence in helping us finally secure something we had been pursuing for years without success through other DME providers. Their support made all the difference, and we cannot thank them enough.

I would highly recommend A C Adderson to anyone who needs medical supplies. We have been customers for the past few years and have had great customer service, products, delivery and pricing on all our orders. They are very customer focused.

I can't begin to express the genuine love and compassion expressed during my sister-in-law's time on hospice by AC Adderson Healthcare. Yes, there were items provided by Medicare, but nothing could compare to the personalized customer service provided by the owners themselves. When we ordered an item, it wasn't just here on time. It was here in the blink of an eye. And hand-delivered by the business owners, Terry and Shonda Pfeil. Anyone can sell medical supplies. But the genuine love for their end-users as well as clients is unsurpassed. I truly stand behind the statement that you simply will not find a company better suited to fill your medical supply needs. I wish I could post a 10-star review.

Jennifer J – Feb 28 In a time when most companies don't have a clue as to what customer service is, this company could teach others. Combine that with great prices on the products I was looking for and they have a winning formula. And they will ship the things I need on an ongoing basis. They are definitely a refreshing company to do business with.
