Chestnut Oak Dental, Cold Spring NY

Chestnut Oak Dental is an attractive country dental office that uses state of the art equipment and procedures. Mary Costigan, DMD and prosthodontist, hygienist Jen and assistant Bridgette are all very skilled and experienced. They are friendly and caring and do their best to make your visit pleasant. We have been there several times and recommend them highly.

Just wanted to thank Dr Mary Costigan and her entire team for a wonderful experience! Having been to dentists all over the world she has shown me that she has extensive experience, that she is passionate about what she does and that she really is concerned about her patients' well being. She showed me such kindness and patience I will be forever grateful! Thank you all so much from a previously very nervous and difficult patient! I aim to continue to do better.

So happy to go here! I have hated going to the the dentist and often avoided it. Mary and her staff are incredibly friendly, caring and helpful. They made me feel so comfortable. They are very gentle and thorough. The office is clean and comfortable. I am so very happy my children can go here and we are all in the same office and I couldn’t ask for a better experience. I certainly do not mind going to the dentist anymore. Thank you!

I was a little concerned when I learned that Dr. Pirraglia was selling his practice. I had been seeing him for years. Well, my fears were alleviated with my first contact with Chestnut Oak Dental. I had broken a tooth and called first thing Mon.morning. Within 15 minutes I was in the chair and Dr. Costigan was checking me out and she wasn't even supposed to be working that day. She had just come in to do some paper work. The entire staff was great. I couldn't be happier.

I have been a patient of Dr. Pirraglia for over twenty years and will truly miss his professionalism and wonderful bedside manner, however, my first visit with Dr. Costigan assuaged any concerns of this type of patient experience continuing, very professional, great bedside manner, a great overall experience.

My experience at Chestnut Oak Dental was so pleasant I just had to share! My cleaning was superb, my teeth and gums feel great. I look forward to being in their care going forward.

I rarely write reviews but I just went to this office for the first time and was blown away by their service - I have to share. The office is in an unassuming building behind Yannatelli's Wines & Spirits and when I walked in I was so pleasantly surprised by the inviting atmosphere and kind woman working the front desk. She knew exactly who I was and brought me back to the the doctor immediately. I saw Dr. Mary Costigan and Bridget O'Brien and both were incredibly friendly and easy to talk to. They were patient and very thorough with my exam. I was impressed from the moment I stepped in to the moment I left. I'm moving and I'm so sad I finally found a dentist I love and they will be far away. I truly hope they succeed as I know they are a new practice and I hope everyone gives them a chance. You won't be disappointed!

When notified that Dr. P was retiring. I was terrified. He had been my dentist since my first dental visit. I decided to give Dr. Costigan a try and oh my. SOOOO glad I did. She and her staff made my children and I feel right at home. Dr. C even made an after hours check in to make sure my youngest son was okay! Still has the same small town feel. Not only is her work great but her compassion for others shows immensely. Thank you for all of your hard work in getting acclimated to your new office.
Also thanks to Dr. P for carefully waiting to find the “right fit” until you retired. In my opinion you could not have found a better person for the job. Best wishes to you all:)

We will definitely be staying️

Great place for taking care of your teeth! I just had one new filling and a replacement. Good, competent work, dentistry as gentle as Dr. Pirraglia’s, who has retired. Reasonable prices.
