Inside views from people on our team

During my 12-week internship, I immersed myself into the culture here at Merck. I was able to get hands on experience and see for myself how my contribution helped the team meet their goals. This allowed me to sharpen my confidence, communication skills, and professionalism. My time in Omaha, Nebraska was one of the best and I’m grateful that Merck allowed me this opportunity to showcase my talent.

Our Animal Health division being committed to establishing and maintaining a tradition of diversity and inclusion is important in order to push beyond all barriers for innovative success. The committed focus on MANRRS, innovation and critical constructive collaboration is what it will take to maintain our industry for the generation to come!

Devon White
Associate Director, Gulf Coast Region, Companion Animal Chattanooga, Tennessee

The intern program with Merck Animal Health has opened so many doors for me in my career. Starting in the global aquaculture space and transitioning into a full-time marketing role for the US Livestock Division, Merck has given me the tools to think outside the box, network effectively, and make a difference in the animal health industry. I’m continuing to grow and learn from this company each and every day.”

When I arrived I was greeted with smiles and warm energy. I enjoyed being able to share my MANRRS experience with the Merck Animal Health team and encourage other MANRRS members to seek opportunities with the company. Together, Merck and the MANRRS organization have left a lasting impression on me and so many others.
