Remmy V.

I strongly recommend OG Dental for those looking for a new dentist or looking to switch. The front desk ladies were very welcoming, knowledgeable and helpful with scheduling and finances. My hygienist, Leah, and Dr. Busch were both great at educating me in the procedures/treatment plan I need to have done and the reasons why. I hadn't been to the dentist in years and the quality of care and attention was excellent! This office is beautiful, modern and also family friendly!

Everyone is amazing and friendly! Dr. Busch is a normal down to earth guy. The front desk team is always on their game. Danielle is the best hygienist going. So happy I found this group.

I've been a patient of OGDA since 1988 and have been very pleased with the care I've gotten. The professionals and staff are all totally dedicated to the dental and overall health of their patients.

I have never been to a dental or medical office that was so welcoming and efficient my first visit went with ease. The receptionist knew who I was upon my entering the greeted me with the biggest smiles which was a great start. I then went on to meet the hygienist Kate who cleaned my teeth like never before she was very knowledgeable and made sure I was comfortable every step of the way, she then called the doctor in who was a really cool dude he spoke to me in dental language I can understand made sure before leaving I understood everything we discussed. I do need a few more visits, but I plan on now switching the rest of my family. Thank you Dr. Busch and Staff

It is rare to find a dentist who has excellent credentials, state of the art knowledge and equipment, and a responsive and caring staff. Dr. Busch and his support team accomplish this in an exemplary fashion. His care has been excellent in all ways. I would highly recommend his practice to anyone with dental issues.
