Please wait in your vehicle if you arrive more than 15 minutes before your appointment time. We require the accompanying adult to wear a mask and recommend all people use hand sanitizer when entering the office. Our clinic remains a safe and clean space to continue administering care, as we are constantly disinfecting our facility and equipment.

After working as an associate in Chicago for five years, Dr. Keta wanted to put her personal touch on your dental experience. As a mother, she knows the importance of a safe and inviting atmosphere to help children flourish. Choosing a dentist you can trust with your children is a big decision. The Little Critter team wants you and your family to feel comfortable and educated after your time with us.
Services
Dr. Michaella "Keta" Radich Heitzler is a board certified pediatric dentist. She grew up in Neenah, Wisconsin and is a country girl at heart. After attending Marquette University and graduating magna cum laude, she traveled to 33 countries in Europe and the Middle East to satiate her wanderlust and love of travel.
I'm Matthew, the office manager at Little Critter. I grew up in Neenah and went to Fox Valley Lutheran HS before attending Texas Christian University and finishing up at UW-Oshkosh in business. We have two daughters, Ahava and Artemis, with a little guy on the way. I love golfing, Bears football, and spending time with family and friends.
I feel so lucky and happy to have found Dr. Keta. Dr. Keta, and her team, are so patient and kind to our children. My son and daughter actually ask to go back to the dentist because they have such a great time. We are so lucky to have found Little Critters! We just moved here and our dentist from Phoenix recommended Dr. Keta.
Even babies who barely have any teeth get cavities. It's more common than you think. Known as Early Childhood Caries or "baby bottle tooth decay, " we often see this when a baby's teeth are exposed to milk, formula, or sugary drinks and high carbohydrate foods. Fortunately, Little Critter Pediatric Dentistry can help you avoid this problem.
It is always easier to prevent cavities than to treat them, so our Little Critter team gives you the best oral health practices as soon as teeth erupt. Further, decay or breakdown of a tooth that is detected in the early stages is easier and less costly to treat. Dr. Keta aims to educate you and your family about all the steps you can take to maintain healthy smiles.

I was blown away by the care and kindness we received today. I brought all 3 kids for appointments and my 8 yr old who in the past has had horrific experiences elsewhere is excited to come back!
my son ended… up not feeling good and projectile vomited all over me and himself. everyone working helped me get him cleaned up and even had a spare outfit for him to change into!
never would I have expected the kindness and just all around attentiveness of everyone there.
I'm bummed that they only see kids 🤣

We had our first visit and my oldest is very anxious and pain sensitive. They made her feel comfortable, listened to her concerns, and were able to do a full cleaning for her. So grateful we found Little Critters.

Extremely positive experience. My kids were not very comfortable at our past dentist and this has been the best decision to come here. They were friendly, fast, and my kids loved it. 10/10!

Little Critter is AMAZING! My son has had a lot of dental work done here and Dr. Keta has been amazing every time! She works so fast that he didn't even know what was happening! I highly suggest Little Critter!

I can’t say enough good things about this dental practice! My kids have seen both Dr. Keta and Dr. Whitney, and we have nothing but positive things to say about their experiences. From the greeting by Matt at the reception desk to the assistants to the doctors, everyone is so professional and so great with kids! One of my kids has some sensory issues, and Dr. Keta was fantastic with him. We were there yesterday, and my four-year-old keeps asking me when he gets to go back again. Highly recommend!
