What Our Patients Have To Say…
Green Lake Dental and Dr. Castleberry are the best! They work hard to make sure your visit is comfortable and they do quality work!
I am a happy Green Lake Dental patient! The staff is warm, friendly and capable, just what one looks for in a dental office.
I was so impressed with the Dental office, Dr. Castleberry, the staff and the care that I received I actually have transferred all my records from Madison to Green Lake Dental.
I’m a big fan of Dr. Castleberry! He was my dentist when I was stationed at Ft. Campbell, KY and has been my best dentist in my 8 years in the army.
Dr. Castleberry explained every procedure that that was done. Questions were answered and I felt very satisfied with his work.
I worked with Dr. Castleberry for 4 years while we were both serving in the Army as dentists. As patients can usually judge character fairly well, I am confident you will find Dr. Castleberry to be personable and trustworthy. He will would never be the type to overcharge or overtreat.
I highly recommend Dr. Castleberry! He is very knowledgeable and takes the time to explain everything in detail and to make you feel as comfortable as possible. From the moment you walk in, you can expect excellent care in a relaxed atmosphere. He truly is going to be an asset to the Green Lake community!
He is a professional, well rounded dentist. He cares about his patients and will deliver quality dental care to people in the Green Lake community.
As a dentist, one of the ultimate compliments you can receive is having a fellow dentist state that they would trust you to work on their friends and family with no reservations. I can say that Dr. Castleberry has more than earned that compliment from myself.
Dr. Castleberry is a wonderful dentist. I have been his colleague for nearly a decade and have reviewed his work first hand. I highly recommend that you visit Dr. Castleberry if you are within 60 miles (or more!) of Green Lake, Wisconsin.
