Personal Attention
Professional Excellence

“I have a sincere concern for my patients and want to partner with them as a facilitator to provide them with the dentistry they deserve. I have a servant's heart and truly enjoy making a positive change in dental treatment. When I hear words from my patients such as ‘Why was I so worried?’ or ‘That was the most painless appointment I've ever had’, it lets me know I am doing things right.”

Jade DeSmidt, DDS

"I have a healthy appreciation for eating as well as smiling. Being a part of a profession devoted to these things makes me feel pretty lucky."

My Mission

"Everyone deserves personal attention, a friendly environment and excellent care from their dental providers. I hope my patients feel they've found that here with me.
