Lauren Geraci – Assistant
My name is Lauren. I have worked with Dr. Wittmus for over 20 years. Our experience working together makes us unique in the way that we perform dental procedures efficiently and of course without pain. I sympathize greatly with patients who have dental anxiety since I myself suffer from general anxiety. I do all that I can to make our patients feel comfortable before and during their dental appointments. I am very aware of infection control procedures and each procedure I set up for as if I am setting up to be the patient treated. I live in Edison Park with my husband of 19 years and my three wonderful daughters. I am grateful for the years I’ve spent with Dr. Wittmus and our staff and look forward to many more.
Annie Middleton – Office Manager
Hi everyone! My name is Annie! I live in Norwood Park with my husband Tim, our daughter Willow, and our beta fish Charlie. I started in dentistry in 2011 in Fairfax, Virginia, as a cross trained dental assistant/front office personnel. I worked part-time while attending Northern Virginia Community College, where I graduated with my associate’s degree. In 2013, I moved back to Chicago to attend the University of Illinois, where I graduated with a Bachelor’s degree in biology.
I couldn’t stay away from dentistry, and luckily, I found that Dr. Wittmus was hiring! I have been with this office since 2014! I am extremely passionate and am here to help you with any questions or concerns about dentistry, billing, insurance, or your treatment.
My favorite part about dentistry is when we can convert patients with dental anxiety (that haven’t been to the dentist in years) to patients that we see routinely! Additionally, I love when patients can “spit back” (no pun intended) dental information that we try so hard to teach!
My most used dental products are the Oral-B Genius electric toothbrush, Sensodyne toothpaste (the fresh mint flavor is the best, nice and minty!), Listerine Ultraclean floss, and my Waterpik. I definitely practice what we preach!
Natalia Mitchell – Assistant
Hello, everyone! My name is Natalia, and I live in Jefferson Park with my Boston Terrier, Jackson. I’ve been working with Dr. Wittmus and the Grateful Dental team since 2014, which is when I first joined the dental field! I was previously working in the beauty industry as a licensed esthetician and makeup artist. When I was studying anatomy of the face, head and neck muscles, etc. in esthetics school, I never thought I would be applying my knowledge in a completely different setting, but it worked out perfectly! Dr. Wittmus trained me to be his dental assistant, and I’m cross-trained to help out at the front desk as well, so you may catch me answering the phone if you call our office.
My favorite part of dentistry is definitely getting to know all of our amazing patients. I’ve gotten to meet some really great people over the years! I also love learning all the new technology in dentistry and applying it in our office, which ensures that we are giving our patients the highest level of care available.
My favorite dental products are definitely my Sonicare toothbrush (even though the rest of the team prefers the Oral-B), and my Invisalign aligners!
