Meet the Team

Meet Rachael


Hi & welcome! My name is Rachael and I am the office coordinator here at SerenityNP. I have worked with Carolyn Johnson as a receptionist and administrative assistant for several years prior to transitioning with her to Crystal Lake.


In my spare time, I love spending time with my husband and 2 daughters. We enjoy watching sports (both my daughters play softball and volleyball), listening to live music, & just enjoying the outdoors whenever we can. I also love to cook, bake, and attempt DIY projects!


I will be the friendly face you see when you walk through our doors and the warm voice you hear when you call. I take pride in treating all clients with courtesy, demonstrating professionalism, and dedication to my work. I look forward to serving you during your journey with Carolyn.

Meet Molly


Hi I’m Molly Johnson. I graduated two years ago as a registered nurse from OSF St. Francis Medical Center College of Nursing in Peoria. I currently work in a busy Emergency Room in Rockford. I love my work as every day is always exciting and different. I love learning new things and helping others in need. I have always wanted to be a nurse because I love being a voice for the underdog. I also have a growing interest in wellness and holistic care. 


I enjoy spending time with my friends and family, working out and listening to music. I have a 3 year old Golden Retriever named Grizzly who is my shadow. We enjoy long walks together and he is always down for any adventure. I also recently purchased my first home and I’m so excited about the new memories that will be made there!


I look forward to meeting you and helping you on your journey to enjoying good health.

Rachel at the front desk is stellar! As someone who despises making phone calls, calling Serenity is easy for me thanks to Rachel. Take charge of your health with the help of Serenity NP. You won’t regret it.
