Bret A. Van Dyken, D.D.S.
I want to personally share with you how excited I am to be returning to my hometown and taking over Dr. Schoenwetter’s practice. My wife, Katie, and I are looking forward to starting this new chapter of our lives along with our daughter, Skylar. I am well aware of how respected Dr. Schoenwetter is by all of you, and I know that I have very big shoes to fill. As your dentist, I want you to know that your trust and comfort with me are extremely important. I spend a great deal of time at continuing education courses so that I can provide you with the latest research-based treatment in all areas of dentistry and care for you in as efficient and comfortable a way as possible. I am looking forward to getting to know you not just as patients but as friends. I want you to get to know me too. At appointments, you will likely hear me talking about something silly my wife said or the newest thing my 1 year old daughter has discovered. When I’m not at work, you will likely find me golfing, spending time on the river, or researching a new recipe to try on my family. I also have a passion for mission trips and have traveled to South America four times with medical missions teams from Woodlands Church. I am anxious to meet all of you in the coming months. If you ever have questions or need me in an emergency, I am just a phone call away. Please feel free to contact me anytime at the office or on my cell phone (715-630-7031).
