Meet Our Calgary Dental Team

Dr Tasneem Rhemtulla, Calgary Dentist

Meet Dr. Tasneem Rhemtulla DipDH, BSc, DMD


My dream to pursue dentistry as a career path was inspired by a young patient who had moved to Canada from the UK.   This patient had heavy brown staining on her front teeth.  She would hide them every time she smiled.  With a simple procedure of dental bonding, we were able to mask the staining and transform her smile.  As a result, her personality changed from shy and introverted to friendly, outgoing, and confident in just a few weeks!  That was the power of dentistry and I wanted to be Making that kind of Difference!

Dr Rhemtulla with patient

I started my post-secondary education at the University of Alberta in dental hygiene and then continued on to the University of Manitoba where I graduated from dentistry in 2004.   This is an exciting time to be a dentist with the field constantly evolving with new products and technology.

As a practice owner for the last 8 years, I have dedicated my career to providing comprehensive, quality dental care to my patients in an environment based on service, compassion and trust. I have continued my education by taking courses through LVI, California Centre for Advanced Studies (CCADS) Dental Advanced Implant Training, Sleep Dentistry, and Invisalign.   I am proud to offer all of our patients a boutique personalized service with attention to detail.   As a clinic, we are committed to listening to our patients and ensuring our goals and objectives for dental health match theirs.

When I’m not working, I enjoy spending time with my husband and 2 children.  This past year, we’ve realized the importance of family and spending quality time with them.  We have enjoyed board games, biking, hiking, and golfing.   We support local charities and volunteering in many different aspects locally and internationally.  Giving back is a big part of who we are!
