Why ChooSE PDG?


  • We don’t let you wait when you’re in pain- If you have a dental emergency, whether it’s a toothache, a broken tooth or a lost filling, we know it’s important that you get seen as soon as possible. We reserve special time in our schedule for patients like yourself so that we can see you the day that you call us. As our patient, you can rest assured that you will always be taken care of, even when everyone else is closed or busy!
  • We put your interests above all- Our focus is on treating you like family, in fact many of our patients are our families and friends and we extend the same concern to each and every patient we see. Today, some dentists are handcuffed by insurance companies and are forced to limit their services based on what the insurance company think is right for you. We think that’s wrong, and always offer you all of your options and recommend the care that is the best fit for your individual situation. 
  • We make dentistry comfortable….- A dental visit does not have to be unpleasant and scary anymore. We use the most advanced technologies to make your visit relaxing, such as using the most advanced and comfortable dental chairs. We also offer different ways to make you more comfortable, using the latest advanced in nitrous oxide so you can snooze through your dental visit!
  • All your dental care in one place- Family dental offices typically only offer basic dental care. If you need to replace missing teeth, straighten your teeth, remove painful teeth or get rid of a toothache, you often have to go to a distant, unfamiliar office. We know you are busy and would rather get everything done in the same familiar, caring and convenient office, so we have invested in the equipment, technology and team training necessary to be able to take care of all your needs here.
  • We can see you when others can’t- You have a busy schedule. Work, picking up kids from school, going to the gym, getting groceries…..sometimes it’s hard to fit a dental appointment in the middle of the day and we understand. We are offering more days of service and extended hours with early morning and evening appointments to make it easy for you to fit dentistry into your busy life.
