    About our Dentists

    Dr. Asena Akcasoy


    My journey in dentistry started in 2010 when I started studying at Istanbul University, Faculty of Dentistry. Over my academic years, I gained hands-on clinical experience to become a skilled dentist who provides patient-focused care.

    In 2015, I moved to Toronto. Immediately I started the equivalency process to become a practicing dentist in Ontario. After completing the exams successfully and receiving my license I proceeded to take many continuing education courses to update my knowledge on new techniques and materials.

    Since I was a child, I have always loved helping people and putting a smile on their face. While I was deciding what my career would be, it was important to me to combine, giving care to people in need, finding solutions for their problems and my passion for art. For me Dentistry is a perfect combination of art and medicine.

    Since the first day I started my journey in dentistry, I have enjoyed every second and over the course of the past 9 years, dentistry turned in to my favorite hobby.

    I believe even with a smallest smile we can brighten people’s day and make a huge difference in their lives. I am so glad that I have an opportunity to give my patients the biggest smile in a warm caring environment.

    Dentistry at Momentum, has become my happy place because I know I work with a team of amazing, caring, professionals that see dentistry the way I do. I am so proud that we all have the same ideal for all of our patients: `excellent , outstanding, professional patient care`

    I am a member of the Canadian Dental Association , Ontario Dental Association and I am register to Royal Collage of Ontario.

    In my spare time, I enjoy painting miniatures and sketching, as a foodie, discovering new recipes and tastes.

    Dr Kevin Lim


    I was born & raised in Toronto, where I was fortunate to be exposed to dentistry at a young age; I witnessed the growth of my granduncle’s dental practice, which was predicated upon hard-work, perseverance, and development of trust among his patients. Although he has now passed on, he had a significant influence on my decision to pursue a career in dentistry, where I’d be able to positively impact patients’ lives while building friendly relationships.

    Following my undergraduate education at Western University, I decided to return home to complete my Doctor of Dental Surgery (DDS) degree at the University of Toronto.

    I’ve always been committed to providing patient-centered care while recommending the most up-to-date evidence-based treatment. Not only have I dedicated my time to patients here in the GTA, but I’ve also traveled to communities in Cambodia, Peru, and Panama, where I volunteered to provide dental services to children & adults who lack access to dental care. To serve you better, I’m continuously improving myself as a dentist through unique clinical experiences and continuing education courses.

    When not in the dental clinic, you can find me staying active in the gym, participating in sports, and exploring new hiking trails. I’m always looking for new places to travel with my friends & family; I’m open to suggestions!
