Gene Sigler was my dentist for the two decades I was in the Bay Area. His work has always been thorough and results successful.
Of two bridges he crafted and installed in the early '70s, I still have one (in 2008), and the other was replaced recently. They have been trouble free and easy to clean.
Gene's office has an airy quality with art that is actually interesting. Everyone's spirit there is high and you can feel that they are all fully engaged in their work.
Most importantly, I have always found that Gene listens to my concerns and gives me considered answers based on solid experience, even including 'I don't know.", the hardest answer to give.
