Meet Dr. Geiger

Hi, I’m Dr. Mary Geiger! I grew up right outside of St. Louis, in a town called Fairmont City, IL. I’ve always had a passion for science and helping people. I started my journey at McKendree University, where I earned a B.S. in Chemistry. I then went on to Southern Illinois University School of Dental Medicine, graduating with my Doctor of Dental Medicine degree in 2019. After dental school, I spent four years in public health dentistry, working in a rural clinic in Missouri. There I had the chance to serve an underserved community, which is something I’m very passionate about.

I’m thrilled to join Watson Dental Associates, where I can continue to provide high-quality, gentle care to my patients and grow in my career. Outside of work, I enjoy staying active—whether I’m out bike riding, trying new recipes in the kitchen, or tackling a home improvement project in my old South City home — there’s usually something keeping me busy. Otherwise you can find me spending time with family and friends or relaxing with my 2 cats, Milo and Henry.

Outside of the office, I’m usually exploring the outdoors with my dog, Denver — a border collie/lab mix who never turns down a long walk, a hiking trail, or a well-earned pup cup from Starbucks. When I’m not out adventuring, I love craft days with friends and spending quality time with my nieces and nephew, who always keep life fun and full of laughter.

Everyone was very nice. They were very easy to talk to and made me feel very welcomed and comfortable. They took their time to explain what they were doing to me in detail and made sure I understood and was comfortable with it. They also made sure we were on the same page on the procedure that was needed to be done to get the results I wanted with the least amount of time necessary for recovery and the final results give or take any small hiccups along the way. I'm very satisfied with our out come of my visit today. Thank you. I am looking forward to the finish product in the future.

I always have a good experience at Watson Dental. I've had dental work with both dentists, and they always put patient comfort first. I love my hygienist, but when I've had a substitute they have also been wonderful. I also want to commend them for not pushing sales of services or devices like other dentists I've been to.

Everyone is very nice. My hygienist, Katie, did a great job cleaning my teeth. She also did a periodontal check. I love that the office bills my insurance instead of me paying and then sending it in for reimbursement.

As a child I had more cavities than teeth. Then permanent teeth grew in 100% crooked ... so I've spent hours, weeks in dental chairs during my lifespan... including visits at San Fransico Dental School. Therefore I feel I'm an expert judge of dental skill, expertise etc. The staff at Watson Dental check all the TOP rated boxes for all aspects of a top notch dental office. They are also very "pain conscious" which lowers the anxiety levels.

We took our three-year old son to Watson Dental for his first dental visit and had such an outstanding experience from the welcoming staff at the front desk to the happy smiles from everyone especially my son on the goodbye. The team was so amazing working with children and helping him understand what they would do on this visit. They got X-rays, a teeth cleaning and a fluoride treatment on his visit! We were so impressed! Dr. Geiger was his dentist and she was so great with him as was her assistant who spent a lot of time with him prepping and cleaning. We can't wait for his next visit and neither can he! This experience will create a lifelong positive experience of the dentist and we are so grateful for everyone at the office who made this visit so great! I've also had my teeth cleaned here with Dr. Sonn and his team and had just as great of an experience. I thought it was important to highlight how great they are with the kiddos though as they're making lifelong positive memories of the dentist! Thank you!

Today was my first visit with Watson Dental Associates, and given that this was a dental emergency, I am more than impressed and satisfied. Dr. Sonn and his staff were amazing. I was in a lot of pain and have suffered some trauma from previous work, and Dr. Sonn was very careful, thoughtful, and reassuring. The procedure was pain-free, and they took their time to make sure I felt safe. I am glad I made the choice to come to Watson Dental Associates.
