STAY AWAY.... Simple: 1. Owner (Dr. Richard Ziehmer) is not trustworthy or professional. A hustler focused on cash and not patient care. Talks a good game but doesn't deliever results and left me hanging with 3 LARGE spaces between my teeth after 4 years of Invisalign. Claims he needs MORE money to fix the gaps and they can be fixed. WHAT? we gave you $5,000 up front for COMPLETE care and not hey I need more money. YOU know better than that. I met with you Personally... flew in to town to do so and saw the whites of your eyes. I was given a heads up of what to expect with you and it Came True. It's not long from now that you will be Done... they don't want to work for you. Your staff... and we are the patients who Invested with you and Trusted you and your business are left Hanging. For those who read this far... RUN! 2. Front office personnel has attitude... clearly is not happy and trying to just minimize the damage with conversations and clearly aren't happy and we bear the brunt of your MONEY hungry focus. Focus on results, patient satisfaction and the rest will fall in place. 3. Turnover of good Dr's who were under Pressure from you Dr. Z. Dr. Freytag and Hoda Salim were professionals who were focused on patients and results. And were always having to make excuses for your poor leadership and money hungry focus!. You are back from south east and NOW we get to see you In Person so we know WHO is creating all these problems. I just wanted what I paid for. RUN everyone... run. 4. Google search NOW showing this office with no affiliation with GRINZ? Website link shows nothing all the sudden. Possible GRINZ finally got smart and Dropped them?! Likely... and we all know WHY! 5. I could go on and on with Specific Details... but if you haven't got the picture yet.. I am not going to be able to help you. That's you the readers and you Dr Z. Dr Z - You are supposed to be better than this. People work hard to earn their money to invest in their smile and they and we TRUST you... and then you treat us like this. It's disrespectful. It's wrong, selfish and not the American way. I am not sure what you will Need to do to change... but it likely starts with a Lot of self reflection and so much more. Do you have that IN you? Usually leopards don't change their spots. I'm Moving On... read more

Just put my 14 year old daughter in braces she had tears of joy, my experience was top of the line so fast and easy the staff and Doctor were so nice and very thorough. I absolutely recommend! read more

Been going to Dr. Z for four years now! My teeth still look the best even after getting my braces off two years ago. I had been referred here from my dental hygienist since I had gone to another Dr in town with a "fishy" name (not naming names) but that Dr wanted to pull teeth! I wasn't down with that, so I came here for a 2nd opinion, and it was the best choice! They see adults, teens, and maybe kids not sure on that one. Staff is really nice and they make you feel right at home! read more

Started w/ this orthodontist office when it was owned by Dr Blase. He retired & we were mid braces so we stayed. The new ownership is very corporate. Packing lots of patients in w/ LONG waits- to get in as well as once you are in the chair to see the dentist. Also sanitary measure are of concern as hands are not washed b/w gloving prior to putting fingers in mouth. That aside- most of the dental hygienists are skilled & put my child at ease. I would NOT recommend & have warned a number of friends about finding a different office. read more

TERRIBLE billing practice, They merged my childs account with someone who shared my address. My account was paid in full, hers was not. I am left with a bill that is not mine, no answers because the billing department only has email, they don't respond. I have been sent to collections and no matter how much I prove my case, they won't remove it and Grinz will not show me an itemized bill. Just a copy of my contract. I'm not disputing being a client. This other girls forwarding address is on a bill with my name. Her account number is merged with mine. It is evident something is messed up but nobody will listen to me. You ruined my credit for something that is not mine. I don't care how good an orthodontist practice is, if they can't get their bills straight it's a huge headache for the client. read more

If you are considering braces look no further. Professional, friendly and knowledgeable all the way around. read more

I would give this place a 0 if it were an option. Save yourself time, aggravation, money and go somewhere else. I would never recommend someone who is dishonest and hurts patients. I have gone to Grinz for several years. Both my daughters used them many years ago and had good experiences. I started Invisalign with them in 2019. Dr Freytag was wonderful and knew what she was doing with Invisalign. When she and the other staff that had been there for years left it all went down hill. I was supposed to be in Invisalign for 15 months. I expressed to Dr Salim several times spacing issues on lower right side. She could never fix the issue. I decided in September 2021 I was done with treatment because it was way past the 15 month mark and felt they didn't know what they were doing. I went in to the Northwest office for them to remove attachments in September 2021 and my tooth was injured. Yajahira was the one taking attachments off. She was using a high speed drill and come to find out she is not licensed to do this, only licensed dentists are. I knew when she drilled into my tooth because it hurt badly. She stopped and said she needed to get another tool and never came back. Dr Salim came over 20 minutes later and I asked her she said I have sensitivity there. Upon looking at my tooth I found that they drilled some of my enamel away (see picture attached). Now both Dr Salim and Ziehmer are denying this happened. read more

Oh my, do I love this place! I can't even tell you how messed up my daughter's teeth were when I came here. We were initially looking at a crowded mouth, the possibility of teeth needing to be pulled and 4 teeth not able to come in. Fast forward to 1 1/2 years later and they have made sure 3 of the teeth had room, and no teeth pulled!! We did need a bit of lasering to expose the 4th tooth but Dr. Freytag did a beautiful job and my daughter was in absolutely no pain. Love these guys, all the front desk ladies always know us. We NEVER have to wait for our appointment and are in and out quickly. I will always recommend these awesome folks. There is no better!!! read more

This place is great! I have to take my daughter in because she has a cross-bite and will be needing braces. Dr. Z was extremely informative.

I would recommend them to everyone, even small children. My daughter will be going back in March. read more

I absolutely LOVE this office. All around great place. Dr. Freytag is so nice and amazing. I get my braces off in two months and my teeth look so much better. Whenever I need to be seen, even if it's a last minute emergency, they fit me in. I would recommend this office to anyone. Chelsea is also amazing. When I thought my braces were too tight and something was wrong she saw me no questions asked and took the time to check when they were about to close for the day. This office has gone above and beyond for me and exceeded my expectations. 10/10 would recommend. read more

Dr. Z was highly suggested by quite a few medical professionals in Tucson. Amazing that such a young guy is such an amazing orthodontist! His office is professional, clean, and very efficient. He is an amazing businessman and my whole family will eventually be customers. Right now my and my daughter go to Grinz. I shopped around and went to all the offices on the NW side before going to Dr. Z. I am really happy with him and hope that you also choose his office. read more
