Been going to Midwest Dental for over 5 years now and have never needed anything more than xrays and cleaning. I feel like in the past I have been pushed or forced into some procedures with other dentists just to pad their pockets. I've always had Heidi as my hygienist and she is GREAT!

My first appointment with Dr Gavino went very well. He was engaging, knowledgeable, and skilled. He identified some concerns in his examination and we worked together to develop a care plan. I feel I made the right choice in choosing Dr Gavino as my dentist.
My son, that is 3, does absolutely great with the providers at Midwest Dental. They explained everything to him and that really helped his experience at the dentist. The workers have even gone along with his imagination like the chair is a fishing boat with his imagination that has helped him. Imagination is everywhere even in the dentist office =). Which to me is a form of kindness to make a patient feel comfortable.
Everyone at Midwest Dental is friendly and make you feel comfortable.

I have seen Dr. Peterson for many years now and I always enjoy my appointment. He takes pride in his work and wants you to have a pleasant experience. I love catching up with him and Heidi. The office staff is always friendly and efficient. Just FYI I started seeing him around 50 because of my fear of dentists, don't wait like I did
I had my first appointment with Dr. Petersen and staff and could not be happier. Because of the extensive x-rays (which were no more difficult than any I have had previously) and thorough checking of my gums, Dr. Petersen was able to diagnose and present a solution to a problem I have had for over a year. My previous dentist worked on this issue three times and could not find an answer. All of the staff were friendly, courteous and willing to rise above average in their treatment of me. I recommend this office completely. I did read the previous bad review and, seriously, cannot imagine these same people as being rude and below par in their duties. Please give this office a try and I think you will be as pleased as I am.
My family and I have been going to Dr. Petersen for as long as I can remember, we have always been well taken care of! From emergency visits to routine check ups we’ve experienced them all and always been satisfied!
Never had a problem with my experiences at this office or with the staffing
Such a great staff. Super good with kids, took 3 year old for first teeth cleaning fearing the worst...but Denise was outstanding! Had no trouble getting my lil trouble maker to allow her to clean teeth. Such patience she had! Showed him everything, let him touch and feel it, explained things to him so he could understand!!! Best dentist office there is!!!
Very friendly staff! All of my kids says that their dentist is their most favorite out of any dentist they've ever been to!
Great place to have anything done on your teeth. They really care that you get the best of everything you need done.
When my longtime dentist retired, the remaining dentists in his office decided to not take our insurance. We looked for an alternative and then the flyer came in the mail. We saw Dr. Daniels and instantly connected to this compassionate and capable doctor. He has gone above and beyond to help me overcome my anxiety and make the best decisions for my dental health. I trust him. He has helped so much and is very gentle. I hope he stays around for a long, long time.
Shawn and his staff are the best. My family and I have been patients for years and I can not say enough good things about the kindness, courtesy and wonderful demeanor of the whole office. It is always a pleasure when dealing with Midwest Dental.
I have been with this dental office for many years and really appreciate their professional staff. Dr. Petersen and his staff are awesome and put you at ease during the visit! Thanks for your service to the community!

Our family has been long time patients of Dr. Markham, clear back to when he started his practice in Anita. We moved away from the area for several years, and I was disappointed to find that I didn't get the quality of care and service that Dr. Markham's office has. The dental staff is extremely professional and thorough; every small comment is met with concern.
great dentist, great staff, they went over the options i have and explained it to me. they called me the next day to check on me and see how i was getting along. best dentist ive been to in years. highly recommend this dentist
Absolutely phenomenal experience from Cyndi at check in to Tamie and Dr Markham and the hygeniest Hayley it was a wonderful experience! I would recommend all of them to everyone, it was and always has been a great experience. Doc Markham, even though he can't go left, is second to none a true one of a kind gentleman!
We have been patients of Dr. Markham since he first opened his Atlantic office. We've never had a bad experience. The office is sparkly clean, easy to get to, and has plenty of parking. The staff is friendly and efficient. We have twice a year check-ups scheduled and rarely wait more than a few minutes beyond our appointment time. On the rare occasions when we've had minor dental emergencies we've been able to be seen by Dr. Markham right away--we know he has come in early or stayed late to be sure we were taken care of. Denise is a wonderful hygienist. Dr. M. is an awesome dentist and one of the most gentlemanly and genuinely friendly professionals you will ever meet.
Dr. Petersen and his whole staff are all great people. They are very understanding and patient. I have never been to a dentist that was so gentle! I could not feel a thing which was great!!! They are also very nice and kind to everyone! My husband and 9 year old daughter also love going to them. Best Dentist by far!!!!!!
Dr. Shawn Petersen and his team are exceptional. My first routine exam was incredibly detailed and thorough, and when I needed a root canal, I was pleasantly surprised - absolutely no pain (except the pin-prick Novocaine shot), and recovery was smooth. I have never been in such professional, friendly, and competent hands.
