Sherrie Magnusson, LPN
For over 20 years, my calling as a Licensed Practical Nurse and Nurse Case Manager has been simple: helping patients and their families navigate the often overwhelming healthcare journey with clarity, warmth, and steady support. Whether guiding someone through rehabilitation, home care, or complex insurance systems like Auto No-Fault, Medicare, and Medicaid, I take pride in being a true advocate. Over the years, I’ve been honored with recognitions like Employee of the Year (2024), but my greatest reward is always seeing my patients feel heard, cared for, and empowered to reach their personal health goals.
Previous Experience
My path also includes years spent as a business owner, an experience that deepened my skills in leadership, active listening, and thoughtful problem-solving.
Sherrie Magnusson, LPN
Current Role
Today, I bring both a caring heart and a sharp mind to every situation—bridging the gap between medical teams, insurance providers, and loved ones. I believe that healing is a partnership, and I’m dedicated to turning complicated care plans into clear, compassionate roadmaps that bring peace of mind when it’s needed most.
