Our Happy Clients
I’m a guy who hasn’t been to the dentist in years because I’ve hated the experiences enough to keep me from going. But knowing I had to at some point, I found Dr. Wittmus who changed my perspective. I’ve had a great experience going to him and plan to for as long as he is in practice. He put me at ease about getting dental work done, and he works quickly and perfectly. I’m impressed by him and have been recommending him to anyone looking for the best dentist around.
Dr. Wittmus has been my dentist since Day One of his current office location of 20 years. He is one of the most caring people I have ever encountered, and the most considerate and gentle dentist I’ve ever had! Dr. Wittmus returns calls, and accommodates emergencies. I highly recommend him and his equally gentle staff to anyone looking for a professional, up-to-the-minute trained and cheerful dentist!
Absolutely phenomenal! LOVE the entire staff at Grateful Dental. Which, coming from someone who used to have to be dragged to the dentist, is no small feat. The staff is friendly, welcoming and kind. I even make my own appointments which I am told is something adults do. Knowing I used to fear (note the past tense) dentist’s visits, they always ensure I am aware of what is happening and what the next steps are. Dr. Wittmus is just as informative and straightforward. No one is trying to push anything on you at all. Everyone is efficient yet immeasurably kind. I never feel like Dr. Wittmus or the staff are rushing to get to the next appointment and yet, I am in and out with everything taken care of, all my questions answered and a warm, moist towel.
Grateful Dental has been phenomenal. My husband and I are new to the area and needed to find a dentist. Through Yelp, we decided to give them a try! The five star ratings our true and I would rate higher if there were a higher rating. The staff is efficient, kind, caring, compassionate and competent! The office is welcoming and clean. Most importantly, it is excellent dental care with no pain. I can honestly say it is the first filling I have had done in years with no pain. They understand the most modern techniques including digital X-rays Sensors which was neat to be able to understand my specific teeth. Thank you Grateful Dental!
Its very difficult to feel relaxed in a dentist chair with the drills going and the needles doing what they do, but somehow Dr Wittmus accomplishes this. I haven’t been to a dentist in over 10 yrs and I’m so glad I found these people to take care of me (as they do an amazing job). Neglecting your teeth can impact your overall health and I’m so glad the doctor cleaned out an infection that no telling how long I’ve been carrying around. Thanks Grateful Dental!
AMAZING experience. Grateful Dental is hands down the best dentistry I have encountered. The staff there really accommodate to your needs and the atmosphere is relaxed. I have learned so much about oral health and I now look forward to cleanings! Since going to Grateful Dental, one of my personal goals is to be cavity-free in 2017 and I take pride in my teeth.
The absolute best dentist specifically Family Dentist ever!!! My kids love him. I actually like going to the dentist and I’m excited when he says I did well just like a little kid. Absolutely the best dentist I have ever had and every will have. Highly recommended.
Dr Wittmus and staff have been amazing over the decades that I’ve been coming for dental work. Clean office, professional and fun staff, and my teeth feel great. Thanks!
Dr. Wittmus is by far the best dentist I have ever had in my life! He is very caring and knowledgeable and always does what is best for his patients’ well-being. He lets you know exactly what is going on and thoroughly explains all options. And to top it off, he is very timely and compassionate as well. The office staff are extremely professional and skilled, and all together they make a 5 star team. Grateful Dental rocks!!!
Dr. Wittmus and his team are wonderful! You can rest assured that Dr. Wittmus has your best interests in mind with every recommendation and he will not suggest something you don’t need. He is very knowledgeable and you can tell he loves what he does. I love that he will always explain what he’s doing and next steps. Dr. Calderon is great as well! She’s always very gentle and takes her time with you. The entire team is always very warm and welcoming. The attention to details really makes a difference. For example, they will always try to make your experience a positive one and will hand you a warm nap to clean yourself after a cleaning or procedure. Highly recommend them and am so glad I found them!
Dr. Wittmus is an amazing dentist. He truly cares about his patients and is more focused on providing exceptional service than he is just about making money. I can honestly say he is the first dentist I’ve ever had that I enjoy going to see. I highly recommend him and his friendly staff.

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.

Hi everyone! My name is Annie! I live in Norwood Park with my husband Tim, our daughters Willow and Fiona, and our dogs Cooper and Kenzie. 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 water flosser!

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!

Hi, my name is Emily and I am the newest member of the team! My mom has worked with Dr. Wittmus for over 20 years and I am following in her footsteps! In October 2022, I began training at Grateful Dental and I’ve grown deeply invested into dental assisting. Dr. Wittmus and the rest of the Grateful Dental team have been the best teachers and I’ve learned a lot working here. I plan to keep assisting while also continuing to find my career path.

Hi! My name is Sarah. I’ve been working at Grateful Dental since August of 2020. I’ve learned a lot and made many memories while working here. My mom, Lauren, has been working with Dr. Wittmus since before I was born, so working with my mom (and sister) has been great. I am currently pursuing a degree in Music Education at Northeastern Illinois University. I have been playing the flute for about 12 years now and can’t wait to share my love of music with my future students.
