Jill Grzeskiewicz


Jill is a Masters-prepared Registered Nurse who has over 12 years of experience in various hospital settings.  She spent much of her career working in high-volume, fast paced urban hospitals, where she was able to quickly grow her skills and knowledge as an Emergency Department nurse.  She then went on to carry several leadership roles within those facilities, and became passionate about understanding the healthcare system, and how it could be improved.  She is currently back in school, working towards a degree to become a Mental Health Nurse Practitioner.  


Throughout her career, Jill identified a need for preventative, or early treatment, as a solution for overcrowding in the busy Emergency Departments.  This led her to found and build a successful mobile IV Hydration and Wellness company in Baltimore, providing in-home care to patients with the goal of decreasing patient volumes for the highly trafficked EDs.  


In 2019, Jill and her partner made the decision to move across the country, and found themselves in Gunnison, CO.  She has quickly adjusted to small town living, embracing the Gunnison Valley Community along with its vast opportunities for health, wellness, and fun.
