Conner Costello – Ambassador of Goodwill

Conner Costello is the newest member of our team and serves as our Ambassador of Goodwill. He has been with us since June 2017. He will usually greet you with a smile or chuckle … unless he’s hungry, then you may get a frown. You may see him riding up and down the hallway or hiding under a counter. Wherever he is hiding, be sure to look for him before you leave. He wants to meet everyone and make sure you have a pleasant experience.

When Conner is not working, he spends his time with his family, playing with toys, and sharing his food with his dog. Even if you don’t need to see the doctor, drop in and say hi to Conner. He will be glad to see you!

Review from Cherie
five stars


I had the BEST experience at Salem Creek Family Dental! I had an extremely painful toothache and was able to get in right away and Dr. Costello was AMAZING and so was her assistant Miranda!! They helped make the experience so relaxing it was almost enjoyable! And believe me coming from someone with severe "dentist anxiety" that is saying a lot! I had no pain at all even after the procedure! Dr Costello even called the next day to check on how things were going! I recommend this dentist office to everyone!

Very best staff and exceptional dental care. The office is beautiful, comfortable and spotless. Highly recommend this dental office. I have very sensitive teeth and they always ensure a comfortable treatment. The staff is friendly and work to accommodate patients’ needs.

Dr. Costello really helped me out when I needed a mouth guard for grinding my teeth. She took the time to work with my crazy schedule and went the extra mile to let me know she was invested in my needs! Her office was so clean and welcoming, and both she and her staff are beyond kind. Thanks, Dr. Costello!
