Patient Care Coordinator
“The best thing about my job is interacting with the patients whose lives have been changed as a result of wearing hearing instruments. It is very rewarding, and I am truly blessed to work with people of integrity who love what they are doing. The service and care we offer our patients makes a difference in their lives, and it shows.”
Patient Care Coordinator
“I am so very blessed to be a part of such an amazing group of people who serve and display such compassion to the needs of our patients. I enjoy meeting new people and feel great satisfaction when I see joy on the faces of patients who previously struggled to connect with friends and family, but now have an improved lifestyle because of what we offer them. I appreciate the opportunity to serve and connect with people in a meaningful way, and I thank God and Calvert Hearing Care for the privilege of being able to do this.”
“I don’t get to interact directly with the patients very often, but I do get to enjoy supporting the people who do. We have a wonderful, caring team here at Calvert Hearing Care who make it easy for me to come to work. We all believe in the services and technology we offer because of the stories the patients tell. Staying connected to the people and activities you love is so important. And we get to be a part of helping someone do that!”
Director of Practice Development
“I was invited out of retirement to join the Calvert Hearing Care team and help grow the practice. Promoting the practice in the community has been easy to do, because I believe in our people —their training and talents; our products—state-of-the-art technologies; and our purpose as a group—to help people hear better and rescue those at risk of isolation. I am blessed to play a small part in making what I call a “real” difference!”
