Our Purpose, Ideal Scene & Mission

Our main purpose is to have happy patients with healthy teeth by means of the most advanced technology and impeccable customer service. We are not a clinic; quite the opposite. We deliver an experience of which they are not accustomed. We use the most modern techniques to ensure our patients get the very best we have to offer. We care, and we know that each tooth is connected to a real person. We treat our patients with respect, and we are nonjudgmental in our recommendations. We are the new age of dentistry, and our attitude, generosity, and concern reflect it.

The ideal scene of Greystone Smile Design is one of efficiency, and an atmosphere where patients get more than what they expected. It’s an environment where each team member knows their job and realizes they must carry their load for us to be successful. Each team member must feel a direct connection to this office and must always aspire to be better and get better daily. We will have the most up to date technology, and patients can now forget about their previous fears of dentistry. It’s an office of fun, cheerfulness, charisma, and enthusiasm.

Our mission is to guide our patients along a path of optimal oral health and wellness for life. To non-judgmentally deliver the highest possible level of care with empathy and understanding. To continuously and relentlessly pursue excellence through continuing education, personal and team growth and mastering of leading edge technology. To treat our patients and employees as individuals. To deliver this care with first class, five star service. To respect our patients’ time. To accept our patients as partners in their wellness. To consistently deliver more than would reasonably be expected.
