Board certified since 1999. Past president of the national board. Inventor of the Hybridis™ system. 18,000 smiles transformed. 36+ years of clinical excellence. No smile is beyond saving.
When you bring your child — or yourself — to Dr. Michael Guess, you are not seeing a general dentist who dabbles in orthodontics. You are seeing the orthodontist other orthodontists call when they encounter a case they cannot solve.
Most orthodontists have a degree. Dr. Guess has a career that shaped the field. Here is what makes him categorically different from any orthodontist you may have previously visited.
Dr. Guess didn't just learn to use an aligner system — he invented one. The Hybridis™ system is a patented orthodontic technology that combines the clinical precision of traditional orthodontics with the aesthetics of clear aligners. The result: faster treatment, better outcomes, and a system no other local orthodontist can offer.
Dr. Guess is known throughout Northern California for accepting complex cases that other orthodontists decline. Complex, severe, or previously rejected cases are where his 36+ years of expertise and the Hybridis™ system shine brightest.
