Kyle Oertwig

Hello, my name is Kyle. I have been an optician for a little over 10 years. ABO certified for 2 of those years. I used to work for big corporations, but I’ve found that private practice is what I enjoy the most. There’s a personal experience you have with patients that you cant get from big opticals. Besides optics, I also enjoy anything outdoors in my spare time. Like cycling, hiking, and camping.
