He is an alumnus of Binghamton University and grew up in South Windsor before relocating to West Hartford where he graduated from Hall High School.

Todd is a strong believer in patient-first care with the highest ethical standards. With a history of painting and sculpting, his passion for performing dental procedures to the highest standards of care yield esthetic and predictable long-term results. This has led to his fellow dentists selecting him consistently to be in both Hartford Magazine’s and Connecticut Magazine’s Top Dentist Issues for multiple years running.

Todd is a member of the American Dental Association, Connecticut State Dental Association, Hartford Dental Society and furthers his expertise with the Spear Education Group, a continuing education workshop with other specialists and dentists.

He enjoys traveling to new places with his wife, plays tennis, golf and likes to ski.


Satoko Ono Rubin, DMD, MDSc
Satoko Ono Rubin graduated from Adelphi University in New York before earning her DMD degree from Tufts University School of Dental Medicine. She then completed a three-year program at Boston University where she earned her Prosthodontic specialty. Dr. Ono Rubin also completed a three year Periodontics program at the University of Connecticut which gave her the privilege and distinction of being the only dual specialist in the state of Connecticut holding these two titles. Dr. Ono Rubin practiced in Boston for a number of years but we now have the honor of having her here at Rubin Family Dentistry & Associates.

Her prosthodontics training focuses on complex full-mouth reconstruction cases including veneers, crown and bridge, dentures and implant restorations whether they be individual units, hybrid appliances or complete implant overdentures. Periodontics focuses on the surgical component of implant placement as well as periodontal surgeries such as gingival grafting, sinus grafts, osseous surgeries as well as preventative gum care programs. Dr. Ono Rubin brings these specialties to us allowing these procedures to be completed in the same convenient location and not having to refer our patients elsewhere.

Dr. Ono Rubin teaches periodontal surgeries to the periodontal residents at the UConn Health Center in Farmington. She earned an international award for her clinical research while at UConn entitled “Immediate vs. Delayed Loading of Two Implants Supporting a Locator Retained Mandibular Overdenture.” She is a member of the American Dental Association, CT State Dental Association, Hartford Dental Society, American Academy of Periodontology and holds the position of Secretary of the Connecticut Society of Periodontists.

She is an avid road biker, runner and usually shoots a better round of golf than Todd.
