Dr. John Smith says, “It’s remarkable how our doctors and staff truly care for and respect each other and how that overflows to our patients.”

To pay for school, Dr. Smith, worked 36 different part-time jobs–everything from running a jackhammer on a bridge demolition to washing dishes. He says, “I liked all of those jobs. When I was putting trays of dirty dishes through the dishwasher in a busy restaurant, I enjoyed it.” Even so,” He says with a slight grin, “ I do like dentistry far better than any of the other jobs I have done.” 

Away from the office John pours himself into spending time with his wife, Jane, and their family. “It doesn’t matter what we’re doing as long as we’re doing it together.”

He says something most people don’t know about him is how he loves to sing. “When our kids were young, I’d sing them to sleep every night. I’d go in with the boys and ask them what they wanted me to sing. They would choose and I’d sing to them. I’d kiss them goodnight and go to the girls’ room. I’d ask them what they wanted to hear. My kids nodding off to sleep as I sang to them each night is one of my most precious memories of those years.

That same gentleness characterizes his work at Southern Arizona Endodontics. He loves caring for his patients. He also loves the camaraderie among the doctors and staff.  He says, “They truly care for and respect each other, and it’s pretty cool how that overflows to the patients who come to us”.
