I graduated in 2015 from the Helsinki University where I have also worked as a teacher. I have been working in private practice since 2017. 

In addition to general dentistry I also do treatments that require special skills. I am especially trained in implant dentistry. I have been placing implants since 2017 and do hundreds of implant treatments yearly.

I am passionate and proud about my work. My goal is to provide top level dental care taking your special need into account.

I take advantage of many modern technologies such as 3d-scanning, 3d- imaging and 3d-printing.

I take regularly part in continuing education to keep my skills and knowledge updated.

I graduated from the Helsinki University in 2015. Since 2017 I have been doing mostly orthodontic treatments and I got my specialist orthodontist degree in 2021 from the University of Turku.

I have experience in orthodontic treatments for both children and adults from simple esthetic cases to more complex treatments.

I use a lot of modern clear aligners (Invisalign) in my treatments. With modern digital techniques a beautiful smile can be achieved more efficiently and predictably.

In addition to clear aligner therapy I also do treatments with traditional metal or ceramic braces according to your specific needs and wishes.

I update my knowledge regularly by attending continuing education. I am the Finnish country chairperson in the European Society of Cosmetic Dentistry (ESCD).
