Always superb.
We were seen promptly. The receptionist was pleasant and efficient. Dr Mahler was exceedingly personable and thorough and explained everything in detail. The office was organized and clean with very modern equipment. All aspects of the visit were first rate
When I first arrived at Smile312, my mouth was in complete disarray—I honestly didn’t even know where to begin. That all changed when I met Dr. Mohler. From our very first interaction, he established a sense of trust and professionalism that immediately put me at ease. He took the time... read more to truly listen to my concerns and questions, crafting a personalized treatment plan tailored just for me. I was blown away by his depth of knowledge, ongoing commitment to staying current with the latest advancements in dentistry, and his use of state-of-the-art technology to ensure accurate diagnoses and effective treatments. What stood out most, though, was his empathy and compassion. He understood my fears and anxieties and created a welcoming, supportive environment that made me feel safe. I’m genuinely thrilled with the progress of my dental work and, believe it or not, I actually look forward to my visits! My mouth is still a work in progress, but I’m excited for what’s ahead. Can you believe I’m saying that about going to the dentist? LOL! Isabel at the front desk consistently provides a warm and welcoming first impression upon arrival.

Johanna, the dental assistant, is incredibly professional and attentive, always ensuring that patients feel comfortable and at ease in the dental chair. She is kind and gentle when taking x-rays, making the process smooth and stress-free. After my dental work was completed, she took the time to educate me on proper oral hygiene practices, which I truly appreciated. Additionally, Johanna maintains a meticulously sterile environment—something that is absolutely essential in a dental setting. Her dedication to patient care and safety is truly commendable.
Dr Mahler has been my dentist for over 30 years. Simple cleaning this time. He had done a crown and filled cavities. I have brought family and friends to him. Personable and lets you know what needs to be done . I highly recommend him.
I went in for an appointment to start the process of getting Invisalign, ended up finding out about other more important issues going on in my mouth. Thanks Dr. M. for being honest and candid about the health of my teeth and gums. Health is more important than aesthetics!
Experience is always top tier! Staff and doctor very friendly
Excellent service. I felt very comfortable.
Thanks Dr. Mahler and the dental assistants for providing a professional and excellent service. Update: Dr. Mahler is the best dentist I have had after I visited some other dentists. He is very patient, professional, knowledgeable and trustworthy. He fixed my old crown and recommended another oral surgery expert Dr. Zager... read more for my bad tooth extraction. All was great!
