Every morning, she has coffee ready for the patients and the entire practice. Joan welcomes everyone with a smile. As she puts it, “I like seeing people feeling better. The end results after their treatment plans are amazing!” Joan enjoys helping patients have a stress-free experience at our practice. She provides them with quick and efficient customer service, helping with varying insurance questions, explaining their benefits and assisting them with claims. Joan believes she found Neck & Back Center of Erie by divine intervention. She was seeking care from our office after unsuccessful treatment with her primary care physician. She found success from chiropractic care, and when a position opened up, she was able to fill it. Joan also enjoys gardening and living every single day to the fullest. She and her husband attend a lot of family functions and visit their son in Virginia when they’re able. Joan is the second oldest of 9 children, and her husband is the oldest of 5! They keep busy, as you can imagine!

When Michele interviewed with us, she felt so comfortable and immediately knew it would be an amazing fit. “I’ve enjoyed working for Dr. Bannister and Dr. Coursen, both of whom are such kind and caring chiropractors. They are both passionate about helping their patients and the entire community live drug-free, pain-free lives with chiropractic care!” Michele is passionate about keeping her family away from pharmaceuticals, and working in the chiropractic field helps her maintain the best and most recent information on natural healthcare. Michele is deeply fascinated with crystals and stones, and she loves to research natural remedies for “anything and everything!” Outside of the practice, Michele enjoys spending time with her family, going to the Peninsula, grabbing wings at the local Fiddle Inn, riding her bicycle, paddle boarding and spending as much time outdoors as possible. She has three adult children-Craig, Emily and Amelia. She also has three ‘fur kids’-toy Poodles who are more spoiled than any of her actual children were!
