Starting her career as an associate dentist, gaining valuable experience and training. Rozelle has continued to show passion in her practice with continual professional development; she gained a Master’s degree in Aesthetic Dentistry from Kings College London graduating in 2022 that has allowed her a complex understanding of dental care. Starting the Masters in 2017, having her 2nd child within this time along with running a business and COVID made finishing a little bit slower! She enjoys cosmetic dentistry offering Invisalign, composite or porcelain veneers.

Rozelle works to the ethos that every patient deserves a full and healthy dentition; she works very hard to teach her patients that their dental health is paramount to their overall health. She believes in prevention and tooth preservation, following the principles of biomimetic minimally invasive dentistry. Always using best practices and working with care and precision, nothing is ever rushed. Each treatment is planned and executed to ensure the best possible outcome. She enjoys a good transformation case where she can join her patients on their dental journey, to dental health and a beautiful smile they can be proud of.

Rozelle is constantly learning and more recently engaging in implant dentistry to offer her patients a full suite of dental care.

In 2015 she took over her father Paul Owens’s practice, D4Dentist. A new start deserved a new fresh overhaul and D4Dentist was transformed with complete renovation making it a state of the art, modern dental facility. She is a hard task master to make sure that the patient journey and the standard of care in D4Dentist is always high quality.

Rozelle also has a young family and is a devoted mother, juggling home, and business seamlessly. She also loves staying fit and works out often.
