Our Team

Gina Winkler – Dental Hygienist

She has been working with us for 11 years and a hygienist for 13 years.

I love my career and our office. I like the interaction I have with our patients, the ability I have to help people, and the reward I get when I see people change their habits and work towards health.

What do you like most about your coworkers: “They are great! They are willing to help when needed and we are a team. They are also my friends.”

What do you like best about hygiene? It’s rewarding and challenging. I am not a person to sit at home, I need interaction with people. I know as a hygienist I can make a difference in my patient’s health, and I like that.

What do you like best about Dr. John? He is a very nice and patient person. He cares about his team and his patients. He is always looking for new ways to improve our practice and help our patients move towards health.

What do you like to do when not at work? We have a cottage and I enjoy relaxing there. I love downhill skiing and spending time with my family. I like to experiment with different recipes and try to make them as healthy as possible. I enjoy working out, and I just started taking yoga classes.

Gina’s favorite patient story! We have a patient that I struggled with because she would come in time after time and have heavy plaque and food debris each time. It got frustrating and I was ready to give up. We got a new technology at work that measures plaque and her eyes and ears were opened and she responded well. My frustration turned to feeling like I finally broke through whatever barrier that I had with her. This was rewarding. I think we have a great office to work in, I am fortunate to work with such wonderful people. Our technology is top of the line and very helpful when trying to move our patients toward health.  We have a lot of tools to work with that makes my job easier. We all work very well together.

Becky Kraus – Dental Assistant

She is one of our Dental Health Coach team members. She has been working with us since 2013 and has been working as a dental assistant since 2006.

I like working with Dr. John because he takes time with each patient. He genuinely wants to get to know and understand each patient. He possesses patience and is a wonderful dentist. Dr. Korolewski is always teaching the staff new things and enjoys our involvement in the process along the way.

What do you like best about your co-workers? I enjoy how very friendly, outgoing, and knowledgeable everyone on our team is. Everyone is a team player, we work together to get the job done.

What do you like about dental assisting? I love helping our patients by transforming their smiles, assisting them to improve their health, and educating patients on good oral health. I really like the patient interaction and getting to know each individual.

What do you like best about Dr. John? He is always open to discuss anything. Dr. Korolewski is a great dentist and the patients and staff really enjoy him. He is always learning and wants to do the best for his patients.

What do you like to do when you are not at work? I am married to the love of my life and my best friend and together we have two boys. I enjoy playing outside with my kids and going for walks. I also cherish spending time with my family. Other things I like to do include: watching movies, cleaning, deer hunting, and shopping.

Mary Mueller – Dental Assistant

She has been working with us for since 1998.

I love being able to use my skills and talents to help people. I enjoy getting to know our patients and allow them to get to know me. This process helps to develop a trust and a relationship between us. I really like the opportunity to get to know so many different people. It really gives me a sense of accomplishment to be able to help someone.

What do you like most about your co-workers? “We all work very well together. We truly ARE a team! We are all on the same page. We get along very well on a social basis, so this makes work fun and I think we all really respect each other’s opinions.”

What do you like best about dental assisting? “Working outside my home gives me a chance to interact with different people. The added income allows my family extra opportunities we may not be able to have if I was a stay at home Mom. I also like being a part of a great team.”

What do you like most about Dr. John? “He really truly values the opinion of all of us. He gives us the freedom to be able to work independently and solve our own problems. He really trusts all of us and is a member of our team.”

What do you like to do when you are not at work? “I have two young children who keep me very busy! I am fortunate to be able to work part-time 4 days a week, which gives me a lot of time to be able to spend with my family and volunteering at our kids’ school. My husband and I enjoy gardening and we try to get away camping with the family whenever we get a chance. We also spend a lot of time with our family and friends, there is never a quiet moment around our house – we are always busy doing something.”

Favorite Patient Story: “I really enjoy seeing patients “transform” in our practice. Several years ago, a single woman in her early 30’s had not been to the dentist in many years. She was very scared due to some bad experiences in the past. During her interview with Dr. John, she got very emotional about being there and was crying. She was one of the most nervous patients I had ever seen in our office. After many years and talking her through a significant amount of dentistry, she is now choosing to have dentistry done, asking “when can we do the next step?” She moved to IL and now drives several hours to come see us. Seeing how far she has come really is impressive.”

Shirley Sinclair – Administrative Assistant

What do you like best about your co-workers? I enjoy how helpful and nice everyone is and so great working together as a team.

What do you like best about Dr. John? He is a very nice person. He cares about his team and patients and takes the time to get to know them as an individual. He is always learning new things to move forward and improve patient health, care and dental fitness.

What do you like to do when you are not at work? I enjoy spending time with family and friend’s especially with my little grandchildren. Going on trips mostly in winter to get away from the Wisconsin cold. Very much like working out at the fitness gym, boating, taking our dog Teka for walks on the beach. I also enjoy biking, gardening and of course shopping! Some kind of home improvement projects always keep us busy.
