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.

FINALLY! I have had the worst luck finding an amazing dentist and competent staff sine relocating from out of state. The search is now over! Let’s start at... read more the front office. Becky. I’ve worked in patient care and client relations for more than 30 years. Becky nails it! From my very first contact via telephone, Becky actually made me WANT to go to the dentist just to meet her! It was time for my bi-annual cleaning…past due actually because it takes MONTHS to get in most places. Nope. I had an appointment with the Hygienist within two weeks. Becky clearly has the front office handled! Thank you, Becky. Hygienist, Sarah. Equally amazing! She was very gentle and more thorough than any Hygienist has ever been. I’m confident that she polished every single surface of all my teeth! I truly enjoyed Sarah as she is light hearted, easy to talk to and very knowledgeable. Dr. Castleberry. Incredible. Most importantly, he validated issues that I have been having for quite some time instead of brushing off my concerns. He immediately had a conservative plan and approach ready for every single issue. I need a little work and figured it would be this Fall before I could get in. Nope. I’m on the schedule for next week! I hope to continue with Dr. Castleberry’s practice for the remainder of my lifetime dental needs. AND they have a nice, squishy little pillow for your head and neck in the chair and just like when I was a kid, they have many different polish flavors available!! Thank you, Green Lake Dental! You’re doing great!
Sarah Van Den Hout
Definitely would recommend Green Lake Dental!!!! What a welcoming, nonjudgmental, sensitive, and caring environment!!! I went in embarrassed as I was very overdue for a cleaning and left with peace... read more knowing that I was in great hands for the remainder of my upcoming visits. I felt heard with my concerns, respected with my minimal pain tolerance, and invested in with the variety of conversations we all had going.
