Always a great experience at Big Smile. Their staff is so friendly and warm. The hygeniests and dentists are very good and super informative. Probably the first time in my life that I actually look forward to my dental checkups! Review by Kristen G
Great office staff. Very personable and efficient. Seems like everyone is hand-chosen for their positions as they all seem to shine within them. Review by Jamie N
They are excellent. I take both of my children here as well. They are 7 and 4 and the staff treats them with exceptional care. Review by Phillip P
Had an emergency visit and didn't think I was going to be given much time because they were booked and I may have to wait because they had to squeeze me in. I was completely floored when they not only examined me but treated me right away. I didn't even sit down in the lobby, when they called me in. Great service and people! Review by Gaye K
