Everyone loves a bright, white smile. Today there are a variety of products and procedures available to help you improve the color of your teeth. Some whitening procedures, such as Zoom, are done in our office with one visit. Other whitening agents can be purchased over-the-counter, however this type of whitening does not whiten your teeth as quickly or as effectively as those delivered by your dentist. Wisdom teeth, or third molars, are the last teeth to erupt in your mouth and are the teeth least needed for good oral health.
We accept almost all PPO & indemnity plans and will gladly process your claim. Please bring the necessary information with you on your first visit. Insurance policies generally cover only a portion of the total treatment cost. Unless other arrangements have been made, we ask that you pay your portion of the bill at the time of treatment.

Best dentist I've ever had! Dr. Kolchansky is hands down the best in Simi. Don't take your chances going anywhere else. Dmitri's (office manager) professionalism is remarkable. He thoroughly explains insurance info and coverage. He is prompt, efficient, and very knowledgeable. Overall, an outstanding group of people work there and you will not be disappointed.

Great service and always explain everything the dentist does. Excellent office staff and great offices and great parking. Always on time and great work. Always briefs you on how much your payment will be after insurance. Set a plan on what needs to be done on your teeth. Always friendly! Great service.

After having a dentist for over 20 years, it's hard to find one that you can see yourself going back to because you are so comfortable with the old routine. After a few struggles with other offices, I finally found Dr. K, him and his entire staff are amazingly attentive and friendly. He is very throughouh with you, tells you exactly what you need in a realistic time frame. I've never been more comfortable with an office! Thank you so much Dr. K and team! I can't wait to start bringing the whole family!

I had my gums deep cleaned. Dr. Arroyo is great. Everything was explained properly. They get you in and out quickly, which I appreciated. They are a well run, competent, team and it shows.

Dr Mark and staff are really amazing. They are very professional and make your dental visits easy, and as pain free as possible, and you still get that attention that is lost at most dental offices. Thanks always!

When you come here you know you are in great hands. I came here to get a root canal, crown, along with some fillings and cleaning and i had an amazing experience. The staff was beyond friendly and helpful, the whole location was super clean and usually i have a lot of dental anxiety but the doc worked very well to accommodate me. I called at least 10 other dentists before finding them and everywhere else the prices were %15-%25 higher than what i got here. Another plus is the doctor speaks Russian for all the fellows Russian speakers!

This staff and dentist are amazing. Let me start off by saying that I have a ton of dental anxiety. I let the staff know this from the beginning and they were extremely accommodating to me being super anxious. The office staff is very friendly. The dentist and assistant who worked on my teeth were amazing. And when I say painless. I really mean painless. I have recommended this office to all my friends and family. Go meet the staff and leave with clean teeth!

This place is awesome! Great service. Great people, very honest and affordable. Got my teeth cleaning it was a good experience they actually knew what they were doing I had gone to another dentist (the one next to reds and that place was not a pleasant experience ). Here at Arroyo everyone is friendly! I hope for anyone who is reading this to go there I recommend!

I went in to see Dr. K for the first time this past Saturday. I had broken off the cap on my front tooth. It was 2 pm and I had plans to see "Wicked" that night. I call his office and they took me right in. They did ex-rays and within 1-1/2 hours I had a temporary cap on. The staff was great and Dr. Mark was wonderful. He'll be the only one working on my teeth from now on. Made it to the show with time to have dinner first. Thanks Arroyo Dental.

Went in here based on the reviews, and I'm glad I did! I brought in treatment plans from 2 other dentists. One of which said I had 14 cavities in my mouth! Dr. K looked at my treatment plans and then at my mouth. Told me flat out that those guys only want money. I only had 2 fillings that needed to be done (which he did them white, per my request!) and 1 wisdom tooth extraction. I was terrified of that extraction, but he got it out in 3 seconds with zero pressure or pain. Office manager is great and rest of staff is super friendly.
