Welcome to Dental Professionals

Dental Professionals is your local family friendly dental office, able to manage everything from routine checkups to oral surgery, sedation dentistry, surgical implant placement, implant retained dentures, crowns, bridges, and Invisalign. 

Dr. Houlihan handles most major procedures in his office, limiting your need to see a specialist. Dr. Houlihan recognizes that for some patients, dentistry can be intimidating because of anxiety or past negative dental experiences. Dr. Houlihan believes everyone should have access to a calm, stress-free dental visit, so he offers all four types of sedation dentistry: laughing gas, oral sedation, IV sedation, and sleep dentistry (general anesthesia).

We provide quality dental care, conveniently in your neighborhood and cater to your schedule. Because your comfort is important to us, we offer many of the modern amenities you’ve come to expect in a dental office including blankets, pillows, and iPads for watching movies and listening to music during procedures. We believe that whatever your dental needs may be, you will be treated with the highest quality dentistry available and with the most compassionate, respectful care you deserve.

Our whole family had a great experience at this office. My 3 year old was very nervous at first but after just a couple minutes with the hygienist she was happy and laughing and had no trouble with having her teeth cleaned. Dr Houlihan was very gentle and checked frequently to make sure I was comfortable during treatment. –Amy M. This review was posted on Google

I have had a lot of dental work. The staff here have worked with me and tailored a plan to help prevent anymore issues. It's worked extremely well over the years. I finally had to have a cap replaced and the dentist worked with me on what my options were and did an exceptional job on fitting the cap in my mouth as I'm super sensitive to things being even slightly off. Very happy! –Heather M. This review was posted on Google
