The People Behind Your Wellness.
IV Wellness™ is not a franchise or a pop-up drip bar. We are a team of experienced, credentialed Registered Nurses, led by our founder Joanie Lingmerth, operating under physician oversight. Every treatment is personal. Every nurse is licensed. Every infusion is safe.
Meet Joanie — Founder & CEO
Hi, I’m Joanie Lingmerth — founder of IV Wellness™, Registered Nurse, and someone who has spent over 25 years caring for people at some of the most vulnerable moments of their lives.
I’ve worked as a medical and surgical nurse, a hospice nurse, and a private duty home care nurse. I’ve been a pharmaceutical representative and a real estate investor. I’m a mother of two sons and wife of an avid golfer. And growing up as a competitive gymnast for over 15 years, I learned early that taking care of your body from the inside out isn’t optional — it’s everything.
Why I Started IV Wellness™
After nearly 25 years as a Registered Nurse, I kept seeing the same thing: people running themselves into the ground, reaching for supplements that were barely absorbed, waiting days to feel better from something that could be resolved in 45 minutes. I’d seen how well IV therapy worked in clinical settings for years and couldn’t understand why no one was bringing it directly to the people who needed it most.
So I built IV Wellness™ as a concierge service that does exactly that. We come to you. We assess your specific needs. We administer a treatment tailored to your body. And we do it with the clinical care and safety standards of a medical practice — because that’s what you deserve.
This isn’t a side hustle. It’s a calling. I am fully dedicated and passionate about taking care of each of my patients, and I bring that same energy to every nurse on my team.
In my spare time, you’ll find me boating, skiing, adventure traveling, or enjoying a Sunday champagne brunch. Because wellness isn’t just about treatment — it’s about living fully.

Karen Knowles, RN, BSN, MHA
Hi, I’m Karen Knowles — Registered Nurse with nearly 30 years of experience in critical care, trauma, pre and post-procedural care, and IV therapy.
My career has been built in hospitals — in intensive care units, trauma bays, and surgical and cardiovascular services, where I’ve served in both clinical and director-level management roles. That experience means that when I arrive at your door, I bring hospital-grade skill and judgment with me. I joined Joanie because I wanted to deliver that level of care in the setting where people actually want it: their own space, on their own terms.
