About Dr Joiner

Dr. Joiner is proud to be a third-generation Santa Cruzan! He attended schools in Aptos and graduated from Aptos High School before attending Cabrillo College, then received a Bachelor’s degree at Baylor University in Texas. After receiving a Master’s degree in Biology, Dr. Joiner graduated with a D.D.S. degree from UCLA Dental School. He then completed a 2-year orthodontic residency and received his specialty certificate in Orthodontics at University of California at San Francisco, at that time considered one of the three finest orthodontic programs in the country.

He opened his own practice in 1986 and has enjoyed the process of keeping it “leading edge” and making it into the place known for creating “Santa Cruz County's brightest smiles”!  He acknowledges his outstanding staff for making it all possible.

Dr. Joiner’s orthodontic practice has thrived over the years as an outgrowth of his relaxed, down-to-earth personality and easy going nature. It matters to him that every patient has a great experience in the office as well as an outstanding orthodontic result. He does whatever it takes to meet the needs of every patient.

Dr. Joiner now lives, with his wife Roberta, very close to where his grandparents operated a chicken hatchery in Happy Valley! They have three animated Portuguese Water Dogs (now famous… thanks to Bo in Washington D.C.). They enjoy long walks on the beach and have been scuba diving for many years (Mark and Roberta, not the dogs!). Besides orthodontics, Dr. Joiner loves nature and backpacks often in the Sierras. He also enjoys skiing, golfing, cycling and woodworking.

Over the years, Dr. Joiner has been a strong support within the community sponsoring several dozen local sports teams, as well as youth-oriented arts activities. He enjoys keeping up with his patients’ involvement in school athletics, arts programs and other extracurricular activities. Dr. Joiner is quite musical himself, currently playing trombone and euphonium in a local brass ensemble.  However, his patients know him better for his humming and whistling while he works!
