Chestnut Oak Dental

I highly recommend Chestnut Oak Dental. The team provides top quality service to their patients, offers a clean and up-to-date office environment and practical considerations for care always in communication with my needs as the patient. The appointments are managed in a timely manner while still being thorough and addressing all aspects of care.

Professional, knowledgeable, caring and thoughtful! Very considerate of your time, your dental hygiene, oral care and teeth in general. I highly recommend going in for a cleaning! I hate going to the dentist but going to Dr Costigan, her hygienist and staff at the desk were a game changer! They cleaned my teeth and explained everything so well! I was so happy when I left. They will NOT disappoint. Thank you Chestnut Oak Dental, our family loves you and your staff! :) We will all see you again soon for another cleaning! :)

Dr. Costigan and her staff are down-to-earth, caring, and professional. Lizette and Judy do our families cleanings. Both are excellent and understanding of their patients needs. They are prepared and ready for appointments. Today, I arrived early and Lizette was ready for me! Where do you get that kind of service? The office is also clean and inviting. The bathroom and the orange therapy soap were an added plus! I highly recommend Chestnut Oak Dental!

Dr. Costigan and the entire staff create a warm, welcoming environment. Judy did an amazing job cleaning my teeth and while the process is not fun, the entire visit was filled with laughter and positivity.
I feel so grateful to be in such great hands and know that Dr. Costigan is providing the best, proactive care for my oral health.

Dr. Costigan and her staff are amazing. Everyone there is so kind and welcoming, and the dental care is truly top notch. Our family really trusts Dr. Costigan. She's so talented and just knows how to talk to patients; we feel so lucky to have found her. I also have to shout out her dental hygienist, Lizette, who is awesome. Lizette is thorough yet gentle, and she puts such wonderful energy into each patient. Highly recommend!

Dr. Costigan and her staff are wonderful! The office is extremely clean and welcoming, and the hygenists are very thorough and have given me a lot of tips for keeping my teeth and gums healthy. Dr. Costigan is an expert at what she does and is very careful and meticulous. She's up on all of the latest techniques. Best of all, she has fit me in twice when I was in pain and needed to be seen right away. I am so glad to have Chestnut Oak here in Cold Spring!

So thankful to Dr. Costigan & staff for saving whats left of my teeth. After years of unsuccessful searching for dental care, I walked in desperately with regular infections abscesses and loose teeth. Chestnut Oak Dental helped me maintain good dental care and treated me with dignity and respect. Great team who truly cares about their patients. You have my gratitude and referrals always!

Lizette, Dr. Costigan’s dental hygienist, has been giving me the best cleanings that I ever had. I was a longtime patient of Dr. Pirraglia and felt bad when he retired. But I made the excellent choice of continuing with Chestnut Oak Dental and Dr. Costigan. The office staff is also very pleasant.

Chestnut Oak Dental is the most professional, caring Dental practice in the entire area. Dr Costigan’s expertise & her empathy along with her staff… Judy, the hygienist, Loretta & Elise the receptionists,
add to a phenomenal dental experience! I have had numerous dentists in my life… No one compares to Dr Costigan! I highly recommend Chestnut Oak Dental!

I used to go this dental office when it was Dr. Pirraglia and was concerned when I heard he was retiring, fearing the unknown and losing what you've had for so many years. Having said that, the transition has bee nothing short of fantastic, with a great dentist and knowledgeable, fun, and welcoming staff that make trips to the dentist enjoyable and not something to dread. I couldn't have thought of a better group of people to take over this business and I am happy they have done so!

I recently moved from Dutchess County and thought I'd find a new, closer dentist. It didn't take long before I realized there were no suitable dentists in my neighborhood. I did some serious research and decided to stick with Dr. Costigan. Her practice is so considerate and capable. I haven't had any serious work done, but the treatments I've had were thorough and gentle. The staff is considerate and capable. Thanks, guys!

Entire staff very nice and knowledgeable. Have had cleanings and fillings with no issues. Appreciate them taking the time to give tips on how I can better take care of my teeth at home. Recommend.

A very efficient, gentle staff of kind women. Dr. Costigan and her team are so good at their jobs. Each one makes me feel comfortable. Highly recommend. -- Anne Pipitone

Very thorough, professional and all round an enjoyable experience at my first appointment. Would definitely recommend this practice.

I had a great experience with Dr. Costigan. The nicest dentist I have ever met. She is very professional and easy to talk to. I love everything about the practice. Lizzette is a wonderful dental hygienist. So gentle but gave me the best cleaning. Everyone is so kind. The office is so relaxing, very clean with great bird books to read. I am so happy that I found them.
I recommend this dentist whole heartedly!

Dr. Costigan is amazing. I have just finished the complicated process of having teeth pulled, implants added, and crowns made. Dr. Costigan orchestrated the entire experience with thoughtful planning and great attention to detail. Her cosmetic skills are exceptional. My new teeth look and feel great! Also, she is really caring and very gentle. Even her Novacaine shots are painless. The nurses and hygienists are top notch, and the office staff is warm and welcoming.

Capable, caring, professional staff. Dr. Costigan is a dedicated perfectionist and satisfaction guaranteed.
