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. Edgar Serra
Dr. Edgar Serra grew up in Aguadilla, Puerto Rico, where his passion for helping others first took root. He earned his Bachelor of Science in Biology from Universidad Interamericana in Puerto Rico and later continued his dental studies at Universidad Iberoamericana (UNIBE) in the Dominican Republic.
Following dental school, Dr. Serra completed his General Practice Residency at Louisiana State University, where he gained extensive experience in comprehensive patient care.
Dr. Serra is dedicated to advancing his skills and providing high-quality care. He has participated in mission trips to the Dominican Republic and Peru and has also volunteered his time providing free dental care in New Orleans.
He is especially passionate about endodontics, surgery, and periodontics, and he finds the greatest joy in helping patients restore their confidence through healthier smiles. He describes himself as humble, persevering, and motivated—qualities that shine through in both his work and his relationships with patients.
Outside of dentistry, Dr. Serra enjoys golfing, camping, and both freshwater and saltwater fishing. A lifelong athlete, he played college baseball on scholarship and even won national golf title at the age of 12 back in Puerto Rico. He and his wife live in Chesapeake with their two children, a teenage daughter and son.
Dr. Carmen Ramirez-Sosa
Dr. Ramirez is passionate about helping patients improve their confidence and quality of life through personalized dental care. She especially enjoys treating complex cases that combine both esthetic and functional solutions, and she is committed to creating healthy, confident smiles that make a lasting impact on her patients’ lives.
She earned her dental degree from Universidad Santa Maria and later completed a certificate in esthetic dentistry at Universidad de Carabobo. Dr. Ramirez then went on to complete her Prosthodontics residency at Rutgers School of Dental Medicine. She is a proud member of the American Dental Association, the Virginia Dental Association, and the American College of Prosthodontists.
Throughout her career, Dr. Ramirez has dedicated time to serving underserved communities. During her undergraduate studies, she volunteered in indigenous communities along the Venezuelan-Brazilian border in the Amazon region. She also participated in programs teaching dental care to children with Down Syndrome and, during her residency, contributed to the Holocaust Survivor Program, helping restore smiles for survivors in need of care.
Outside the office, Dr. Ramirez enjoys spending time with her family and her dog, Thor. She loves staying active outdoors, running, playing tennis, and watching Formula 1 racing.

Front Office
Tess Balsor
Office Manager
Born and raised in Suffolk, VA, Tessa is proud to still call this community home. She has spent the last 15 years working in dentistry, one of the few places where you can completely change how someone feels in a single visit. A confident smile can impact the way someone walks into a room, speaks in a meeting, or laughs in a photo — and being part of that transformation never gets old. Tessa loves creating an environment where patients feel welcomed, heard, and maybe even forget they’re at the dentist for a minute. Outside of work, she is a busy (and proud) mom to three amazing young men who keep life loud, active, and full of laughter. If she’s not at practices or sporting events, you’ll probably find her by the pool, out on the boat with friends, or planning her next adventure. At home, Tessa has a 3-year-old German Shepherd, Kaia, who runs the show and keeps everyone on their toes. When she has a quiet moment, Tessa loves diving into a good book — though with three boys, “quiet” is always relative!
Tessa believes in working hard, leading with heart, laughing often, and making every space she’s in feel welcoming — and that’s exactly what she strives to bring to Portsmouth every day.
