Dr. Larkin and his team are awesome. What a great experience. I did not know what to expect. The team was very professional and so helpful.
Response from the owner:Thank you for your wonderful feedback! We're thrilled to hear that you had such a positive experience with Dr. Larkin and our team. Your satisfaction is our priority, and we look forward to seeing you again!
Tiffany B.
My son has been coming here almost a year. The staff is friendly and I love all the pink!!
First time anyone getting braces and it has been a great experience. The girls are so nice and the office is very clean. Highly recommend
Kelly H.
Today my son received his top set of braces and our experience from the consultation to today with Otto Orthodontics has been amazing. All of the ladies made my son comfortable and they were so informative and we left today knowing exactly how to take care of his new braces. Even though we’ve only been going for a short time, I highly recommend them. They are just lovely 🥰
Nikki G.
I absolutely love Otto Orthodontics! The staff is always so fun, friendly, and welcoming from the moment you walk in. The office is super clean, adorable, and has such a positive vibe. They make every appointment enjoyable and really care about their patients. Highly recommend to anyone looking for an orthodontist who makes you feel comfortable and excited to come in. 5 stars all the way!
Jessy H.
Dr. Karkow and staff were absolutely amazing with our little cleft cutie! Everyone was so awesome and accommodating for such a young ortho patient!
Response from the owner:Thank you for your wonderful feedback! We’re thrilled to hear that Dr. Karkow and our team made your experience so positive. We look forward to continuing to provide exceptional care for your little one!
Kimber E.
Took me a long time to pick a place for my daughter's orthodontist work. And Im so glad I picked this place. They are so nice and so easy to deal with making appts and changing appts. And they are efficient and I love that the appts dont take forever.
Kaitlin T.
such a nice office! very modern boutique-style setup which made me feel super comfortable before my appointment. They also have really cute branding with their accent color being hot pink which I thought was so unique and fun. I came here to get Hawley retainers (my post-invisalign retainers are plastic and not working well for me) so I assumed I was going to have to do traditional mold impressions again 😣 but I ended up not having to! This office has an amazing scanner to digitally take impressions, so no gross putty or uncomfortable trays shoved in your mouth! 😭 🙌 it was such a pleasant surprise and made the appointment way less stressful. all of the staff I interacted with were friendly and helpful :) I’d definitely recommend Otto if you’re looking for an orthodontist! 🩷
Response from the owner:Thank you for your wonderful review! We're thrilled you enjoyed our modern office and the digital impression process. Our team is dedicated to making your experience comfortable and enjoyable. We appreciate your recommendation!
Donielle W.
I had my top braces put on today and had a great experience from start to finish. My appointment was right on time, which I really appreciated. The team explained everything clearly and made sure I understood what to expect during and after the process. They also gave great advice on how to properly care for my braces moving forward. Overall, very professional, efficient, and informative—highly recommend!
Response from the owner:Thank you, Donielle! We’re thrilled to hear about your positive experience with our team during your appointment. Your satisfaction is our priority, and we appreciate your recommendation. Welcome to your orthodontic journey!
Evan G.

Response from the owner:Thank you for your wonderful review! We're thrilled to hear that you find our practice amazing and that Jana provided you with exceptional service. We appreciate your recommendations and look forward to seeing you again!
Tammy M.
This office is unbelievable. The staff and the doctor are great. My son loves coming to his appointment.

Rae N.
Officially got my Invisalign today! Everyone at otto has been amazing! Making me feel as comfortable as possible through this whole experience both physically and mentally as far as explaining everything very well and making sure to answer any questions. All my nerves are calmed and I am very excited to continue this journey with them.
Response from the owner:Thank you, Rae! We’re thrilled to hear you had such a positive experience with our team. Your comfort and understanding during the Invisalign process are our top priorities. Excited to support you on this journey!

We are so pleased to have our daughter with special needs treated by Dr. Karkow and the team at Otto Orthodontic in Fenton. They have been phenomenal with our kiddo.
