Dr. Tyko’s Reviews

Dr. Leonard Tyko and his Team are by far the best in Santa Rosa. Not only do they make you feel like family they go the extra mile in the recover process i highly recommend this place to anyone looking!!!!!

Dr. Tyko has performed 3 tooth extractions for my 6 year old. He is a remakably professional and caring physician who my son finds very interesting. Dr. Tyko is very good with kids and understands what parents are thinking when they hear that a tooth has to be pulled. Overall, his bedside manner is great and I couldn't expect anything more from a physician, given the circumstances he works with. The fact is, no one wants to have oral surgery, but Dr. Tyko does everything he can to make the experience positive.

My son had to go in for an extraction. We were able to go for a consultation, and book the procedure shortly after. The staff was extremely friendly and Dr. Tyko was amazing! He explained what to expect, and when we came in they were super fast! My son was super comfortable and healed beautifully! I highly recommend Dr. Tyko and his staff. They are the best!

Dr. Tyko is realllllllly nice, FAST, and professional. I wasn't fond of the idea of having a wisdom tooth removed (As I am sure nobody is). Initially I came in for a consultation...but they had space available to extract my tooth right then and there (I came with a referral and an xray). He walked me through the steps...and was even kind when I was sarcastic (Jitters???). Before I knew it the procedure was over. I never felt a thing and within 50 minutes of being in the office I was out the door with care instructions and relief! It was...maybe...kinda fun tool. :-P Thanks, Doc!

Dr Tyco has provided wonderful care for both myself and my son. He is attentive, ready to listen and will describe procedures to us in as much detail as we like. He is careful and excellent in his work. He is responsive and works to make everything turn out successfully and to our satisfaction. I would choose him again should we have the need
