Downtown Dental Group

I will always give Downtown Dental (DD) high praise. Mary will always be my favorite. She knows me and knows exactly what I need to ease me through my appointment. My appointment last minute and they were able to squeeze me in. I know most don't enjoy going to dentist, I do because the staff at DD make it all worthwhile.

I want to express my deepest gratitude for your terrific work on my teeth Dr. Costello. You are not just professional but also kind and patient... I'm so comfortable when I'm in your one of two offices. You always make sure you explain everything in a way that I can understand. I’m grateful for the way you help me keep my smile healthy and bright. Your patience, kindness, and expertise truly make a difference! Also your staff is friendly and knowledgeable. Keep up your fantastic work.

The office is ALWAYS AMAZING! From the front desk to the Dental staff. It’s always a pleasure to go!!!

I have been going to the downtown dental group for several years. My hygienist Mary is awesome. She ensures that my dental hygiene is always kept up. She has been taking care of me for quite some time and I never see anyone except for her. Thanks to her my dental cares are stable.

All of my experiences with Downtown Dental Group have been exceptional. Dr Mike is thorough and professional. Mary, my hygienist for the past 30 years, is always pleasant, thorough and gentle. The receptionists and additional office staff are consistently friendly and familiar. They perform their tasks efficiently and accurately. I would highly recommend Dr Mike Costello and his team for any and all of your dental needs.

I previously wrote an excellent review for the hygienist because her clinical work genuinely deserved recognition. The cleaning itself was thorough and professionally performed, and I continue to appreciate the quality of care she provides. However, I feel obligated to share a significant concern regarding billing transparency. I scheduled what I understood to be a routine cleaning and did not request a separate doctor’s visit. I was therefore surprised to discover an additional charge for a doctor’s exam that was neither requested nor clearly explained in advance. Had this been communicated beforehand, I would have appreciated the opportunity to decide whether to proceed. In any professional setting, transparency regarding services and associated costs is a fundamental standard. Patients deserve clarity before treatment — not unexpected charges afterward. What further compounded my disappointment was the lack of follow-up communication. I called multiple times in an effort to resolve the matter and was told I would receive a return call, which never occurred. Instead, I received a bill — followed by an additional late fee — while I was actively attempting to seek clarification. Clinical skill earns trust; transparency and professional communication sustain it. I encourage future patients to ask detailed questions about required exams and billing policies in advance to avoid similar surprises.

Dr. Costello is one of the kindest dentist I've come across. He is patient, knowledgeable and very thorough. I have dental chair anxiety and he is aware of it and makes every visit easy. The staff there is very friendly and helpful. They always greet with a big smile and will keep making sure you are doing good during the whole process.

This is probably the best dental clinic in Milwaukee. The staff and Dr. Costello are amazing! Very professional, very thorough and very kind people.

Dr. Costello is a great dentist! I can be rather anxious, and he is always very patient with me. I've also seen Dr. Senych and she is great, as well. The hygienists, assistants, and front desk employees are all very kind and friendly.
