Joanna is an experienced dental surgeon. She graduated from the Medical University of Lublin in Poland in 2010. After relocating to London, then Wiltshire, she started a family and began to develop her dental career. A committed professional, Joanna is continuously improving her skills and knowledge by attending post-graduate courses and dental conferences both in the UK and abroad. Over the years Joanna grew special interest in cosmetic dentistry (aesthetic veneers, fillings, smiles design), prosthodontics (restoring teeth with dentures, crowns and bridges, including “single day crowns” CEREC), endodontics (root canal treatments) and since 2017 she has also been successfully providing dental implants. Joanna is trained in Relative Analgesia and uses her expertise to treat even those very nervous and anxious patients.

Joanna’s motto is to always treat people the way they wish to be treated – making sure everyone feels comfortable and confident in the service received. Her natural compassion and kindness puts patients at ease and makes their treatment a relaxed experience. With her dedication and passion, she brings back and maintains beautiful, natural smiles.

Joanna, apart from English, speaks fluent Polish and is able to translate for any Polish patients who require it. In her free time she enjoys staying fit, exercising, singing and spending time with her 3 kids and little dog Twix.
