Our Doctors
Dr. Robert F. Morrison
Clinical Director
Dr. Robert F. Morrison is the owner and founder of Morrison Dental Group, serving families since 1992. After completing his service with the U.S. Navy, he opened the practice with a mission to provide genuine and compassionate care for the families of the Hampton Roads region. Over the years, the practice has grown to incorporate advanced dental technologies while continuing to provide patient-focused care for individuals and families.
Dr. Morrison earned his Bachelor of Science degree in chemistry from Southern Illinois University in 1979, followed by his Doctor of Dental Medicine degree in 1982 from Southern Illinois University School of Dental Medicine. He completed a post-doctoral residency in Comprehensive Dentistry and went on to serve as a dental officer ashore and afloat from 1982–1991, including as department head aboard the U.S.S. Guam and head of the Pediatric Department at Norfolk Naval Station.
Dr. Morrison is married to Alison, who serves as Morrison Dental Group’s CFO. They have two sons: Frank, a Lieutenant Commander in the U.S. Coast Guard, and Alex, who is the group’s Chief Compliance Officer. In his spare time, Dr. Morrison enjoys fishing on the Chesapeake Bay, kayaking, and restoring British MG cars. He is also a member of the ADA, American Academy of Sleep Medicine, Virginia Dental Association, Peninsula Dental Society, and the International College of Dentistry.
Dr. Rafael Siqueira
Periodontist
Dr. Rafael Siqueira is originally from Recife, a beautiful town on the coast of Brazil. He attended the University of Pernambuco in Brazil and graduated from dental school in 2010.
He then went on to complete a Masters of Implantology which is similar to a US residency program. After completing that, he joined a PhD program at the Federal University of Pernambuco which sent him to the University of Michigan to do research for his master’s thesis. Once he completed his PhD, he headed back to Michigan School of Dentistry for a 3-year residency in Periodontics. During his time in school and residency, he was able to publish over 30 scientific articles in international peer reviewed journals and write five book chapters. This resulted in a few awards over the years.
Dr. Siqueira’s interest in dentistry started to develop very early in his life by watching his parents who are both dentists. He observed his father teaching students and treating both students and patients with compassionate care. He witnessed a few instances where patients were moved to tears by the results of his father’s care and students whose lives were so strongly impacted by the mentorship his father provided on their path to become a Periodontist or Implantologist. Dr. Siqueira soon realized he wanted to have that same positive impact by being a dentist, educator and researcher.
Dr. Siqueira describes himself as not only family-oriented and very sociable, but also easy-going and calm. He loves being with friends, having a good time and sharing great food. He is typically very optimistic. He is married to Renata, a lawyer, who just recently gave birth to their first child, Thomas. They do not currently have any pets but hope to add a dog to their family in the near future. Dr. Siqueira is a big sports fan, food lover and loves to travel. His hobbies include playing tennis, watching sports, exploring new restaurants, travelling and meeting new people, and learning new languages. A fun fact about Dr. Siqueira is that he speaks his native language, Portuguese, as well as English, Italian, and can communicate quite well in Spanish. He is currently taking a Spanish course to improve his fluency.
