I have been a client of Smiles in Springfield for several years now, and it continues to be the ONLY practice that I not only feel comfortable seeing, but that I insist other people also need to attend. I've had A+ work done by both Dr. Tran and Dr. Grimmer, and had the pleasure of meeting Dr. Phung at my most recent cleaning. She was very courteous and professional, and has an air about her that instantly makes you feel comfortable (this coming from someone who is normally very uncomfortable with dental visits!). I also had the pleasure of Hygienist Diem Vuong working with both me and my daughter, and I'm very grateful for her patience and knowledge during the visit. As usual, the front desk staff were pleasant, and they always work with me to make sure I have the very best experience (and always work with my insurance and explain everything to me!) I would absolutely recommend this dentistry to anyone who is looking for a pain free, calming, and informative practice!
