Olivia, one word, WONDERFUL. I do not know if a kinder soul has been put on this earth. And what a sense of humor! Dr. Benson, as well, so patient answering my questions and ensuring I comprehended and understood the procedure(s) and what will happen. If there were no Batman and Robin, this would be the OG dynamic duo. Thank you for making the one crown a reality within my short timeline.
Sensational Smiles scheduled and saw me same day after I chipped some teeth. Everyone here is super kind and welcoming and take the time to make sure you’re comfortable. Jodi was taking care of me alongside Dr. Anderson and they both made the situation a lot more bareable. Thank you both!
I’ve been coming here for 2 years and recently needed a crown, my first, so scheduled the appointment. Years ago a dentist didn’t numb me enough and caused a traumatic fear from that point forward. Brenda and Dr. Benson were aware of my fear. They were careful, patient, caring, took extra precautions and made it their goal for me to relax and have a positive experience today. I will say I recommend Sensational Smiles to anyone who is looking for a top notch dentist. The staff is friendly, knowledgeable and on point with answering questions. I always leave smiling. I am truly thankful to have finally found a dentist I am 100% happy with!!
Sensational Smiles has dentestry figured out. Every staff memeber is friendly and helpful. The hygienists do an excellent job with cleaning, encouraging better home cleaning, and interfacing with the doctors about my visits. The doctors are friendly, knowledgeable, and are always willing to listen to my concerns. They have awesome technology that can make new invisaline retainers in office as well as being able to scan a cavity and create a perfectly fitting filling same-day. I'm always impressed. Thanks!
Amazing team, top-notch care. Not a patient of theirs, but they worked me in for an emergency procedure during a cross-country drive. Everyone, from Tara and the office staff, to Dr. Swingdorf and Dental Assistant, Brie, were the most welcoming and friendly folks you could ask for. Patient, informative, and professional in every sense. If I didn't live 1500 miles away I'd be their newest regular patient. Thanks for turning a tough day into a pleasant experience!
