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. She is incredibly friendly, professional, and communicates information clearly and effectively—whether it’s about services, appointments, or billing. Isabel takes the time to explain everything in a way that’s easy to understand, and she’s always willing to answer questions or reschedule appointments when needed. Her helpful and approachable demeanor truly enhances the overall experience. 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.
Flawless.
