Dr. Aleksandra was born in 1978. in Belgrade.

She grew up watching her father, a dental technician at the time, who carefully modelled teeth and through play introduced her to the craft, contributing to her choosing the career path at a very young age.

1997 she graduated from the high dental school in Belgrade.

2006 she graduated from the six-year program at the Faculty of Dentistry in Belgrade.

She completed a one-year internship at the Military Medical Academy (MMA) and fully devoted herself to the profession.

She has been working in the dental clinic "314 Dentistry" since 2007. under the mentorship of her father, the founder of the practice Dr. Spec. Branislav Krnjajić. Always seeking continuous education, she is an active attendee on many congresses and a large number of specialised courses and presentations, adopting only what is proven to be the best for her patients.

She predominantly works in the field of dental prosthetics, but is also very close to the practice of endodontics, which after 18 years of work grew close to the heart. Through the procedures in the creation of aesthetic fillings, she has the opportunity to show off her technical dental skills.

She has always considered dentistry a combination of science, art and craftsmanship, and her approach is based on the trust and the respect for individuality.
