Meet The Doctors

  • Dr. Muoi Leong DDS

    Dr. Muoi Leong grew up in Calgary and received her Bachelor Of Science Degree in Microbiology at the University of Calgary.  Looking to continue her education she then continued to the Faculty of Dentistry at the University of Alberta in Edmonton.  She graduated from the Dentistry program with Honours and moved back to Calgary as fast as she could (to cheer on the Flames and Stampeders, of course).  Dr. Leong has been practicing family dentistry in Calgary since 2002.

    Dr. Leong is a certified Botox administrator and also a qualified Invisalign practitioner.  She is constantly updating her skills and spends a great deal of time discussing dentistry on the various dental forums. 

    A true believer in giving back to the community, Dr. Leong has volunteered in many organizations including being an executive board member of the Calgary District Dental Society, the CUPS Dental Clinic, her Community Association, and several local sporting clubs.  She is also a strong and long-term supporter of STARS and the Calgary Humane Society.

    Aside from her 2 awesome children and husband, Dr. Leong's greatest love is food - cooking and eating are her favorite pastimes.  To balance this out she also enjoys hiking and working out on her stationary bike while watching Netflix.

  • Dr. Mark McCalder DDS

    Dr. Mark McCalder grew up in Calgary and graduated from Vicount Bennett High School.  He studied dentistry at the University of Alberta and has been practicing family dentistry for over 30 years.

    When Dr. McCalder isn't making your smile look its best, he enjoys golf, playing hockey, working out and learning to speak German.  

     Dr. McCalder and his wife Cathy have four daughters and one extremely cute grandson whom they love to spoil!
