"I had been wearing the t:slim Pump for about a year before I started working at Tandem. I like that I never have to look at myself in the mirror and ask why I do it. I know exactly what the value of our products are because they’re products I was already using to improve my own health and my own quality of life."

Buyer

"Before Tandem, I worked in the government sector. I was interested in making a big change in my career by finding a job in the private sector that involves helping people with a focus on the medical industry. The culture and atmosphere at Tandem is the best that I’ve ever experienced! Tandem seems to have a knack for hiring employees who genuinely care about their jobs and the impact, big or small, that they have on Tandem’s customers and products."

“I have family members with diabetes, and more importantly, my clinical partner, Chelsie is living with diabetes. A friend referred me to Tandem and it has been a wonderful experience. Tandem really listens to what health care professionals and patients have to say, and takes action directly as a response to that feedback. Knowing that I have the ability to provide solutions to people’s needs is the most rewarding part of my job.”

Clinical Diabetes Specialist

“I have been living with diabetes for 25 years. When I heard about Tandem and what they were doing for the diabetes community I knew I had to be a part of it. What I love most is that a lot of our employees live with diabetes and we understand that a pump isn’t just a pump, it is more personal than that. We take our patients’ feedback seriously and implement needed changes.”

Al

Regional Sales Manager

"I was diagnosed with type 1 diabetes at age two, 36 years ago. I have never known anything else. Checking sugars and giving myself injections was always just another chore, like brushing my teeth or combing my hair. Growing up, I played football, skydived, and traveled extensively. Although diabetes was challenging, I never let it stop me from accomplishing my goals. I was drawn to Tandem because of the focus on making the lives of people living with diabetes better by finding ways to make managing it easier. After using injections for 34 years, I chose the t:slim Insulin Pump to be my first pump. I feel like the t:slim Pump was truly built for me. There is no greater joy than to help a patient who is new to pump therapy take their first steps with our pump, and then hear back from them about how much better they feel about their diabetes management. I want everyone to know that we want to know what we can do to be better than we are today. Tell us what you really think!"

Jessica

Clinical Diabetes Specialist

“I have had type 1 diabetes since I was 11 years old and have been on insulin pump therapy since I was 12. My diagnosis led me to my career of becoming a nurse and CDE and hoping to inspire and help people through my personal experiences of living everyday with diabetes. As soon as I started on the t:slim Insulin Pump I knew that it was a product I truly loved and believed in, and from that moment I kept my eyes open for an opportunity with Tandem. Finally, in 2013, I got that opportunity and I could not be happier to be living every day with the opportunity to advocate for patients to be on the best insulin pump out on the market and help them gain better control of their diabetes. For the first time in my career, I am able to say that I love my job!”

"The passion that fills the Tandem hallways is contagious. I have had diabetes for almost 20 years and I feel so blessed to give back to our community by working with so many caring people on our customer support staff. As a patient and a colleague, I am proud to be part of this hard-working team that genuinely cares about getting to know the people we serve."

“Coming out of college my dream was to find a job in the diabetes industry. I have diabetes and I heard about Tandem through a friend who was using the t:slim and loved how cool and modern the pump was. From then on I kept an eye on Tandem’s job board.”

Mike

Manager, Human Resources Business Partner & HRIS

"I've worked in medical device and biotech for most of my career and the diabetes space is without a doubt the most passionate group of people I've had the honor to work with. Here at Tandem we work with a large number of employees directly impacted by the disease.

Prior to working at Tandem I was consulting, which gave me the unique opportunity to work at several companies over a short period of time. It didn't take long to figure out that this place was different. Cool people, great product, and an environment where your ideas are heard.

If I could implement one new thing here, it would be group hugs every morning. If you don't like this idea, raise your hand, you most likely need it most.”
