DMS is devoted to providing and maintaining a strong company culture that focuses on not only our clients, but also our employees. Though most of our employees are out and about making a difference in medical and home care settings, they are highly valued employees and receive the same treatment as the employees in our office.

Emily Potratz
Administrative Assistant

Have you met Ms. Emily? Emily Potratz has a knack for organization and thinking outside of the box. When Emily is not working, she spends her free time outdoors with her family. Her other main interests include reading fiction, skateboarding, classic video games on the N64, NES, and Sega, and going to the beach.

Emily is also proud to work with an international women’s sorority, Beta Sigma Phi, where she volunteers and raises money for local organizations like the Ronald McDonald House and the ASPCA. If she had to give up anything, it would be impossible for her to give up chocolate Milk.

Emily’s favorite vacation was the trip she took to the Caribbean with her mother when she was 14. Her favorite action hero is Superman; Emily owns many pieces of Superman merchandise (and all Superman movies).

What surprised her most about DMS is how friendly and fun the environment is on a daily basis. While working at DMS, Emily has helped countless individuals in need: from clients, to caregivers, and especially her colleagues.

What most people don’t know about Emily is that she loves music and singing.

Another fun fact is that Emily can’t stop talking about her lovely daughter, Eloise.

Motto: “It has to be at its worst to get better."
