She then spent a year at the Health Science Centre Dental Clinic caring for patients with complex medical issues, and subsequent years practicing at Northgate Dental Centre. Dr. Deng bought her current practice at 1537 Grant from Dr. Terry Mancer in 2007. She practices in all aspects of dentistry, including aesthetic restorations, endodontics, kids’ dentistry, teeth whitening, and wisdom teeth removal.

Dr. Deng met her husband, Dr. Jiayan Guan, in Shanghai Medical School. They furthered their education in Medical Research at the University of Western Ontario prior to attending dentistry at the University of Manitoba. Currently, Dr. Guan is one of a handful of oral surgeons in Winnipeg. Together they provide dental implant treatment, from single tooth restoration to full arch dentures.

Grant Dental Centre was originally established 50 years ago by Dr. Terry Mancer and Dr. Lawrence Stockton. Located in the heart of River Heights, the clinic has long been known for quality dental care. The clinic was recently completely renovated, with central sterilization and new digitalized dental units, and is wheelchair accessible.
