Our Practice
The Unionville Children’s Clinic has been serving the Markham community since 1988. Our commitment is to provide warm and outstanding pediatric and adolescent care where we focus on the needs of our individual patients as well as the concerns of their families.
At the Unionville Children’s Clinic, we provide comprehensive primary care and consultation services for patients up to 19 years old. We believe in preventive health care in a holistic fashion. We monitor children’s growth and development on a regular basis and work in partnership with parents and even teachers in some cases to achieve the best care for our patients. Our experienced pediatricians are also prepared to provide nutritional and behavioural counselling. Should a child require additional medical expertise, we have established a wide referral base of pediatric specialists to assist you. Our referral base also includes doctors and consultants at Markham Stouffville Hospital and Hospital for Sick Children to provide escalated levels of care as required.
Our office is conveniently located in the charming community of Markham, across the City of Markham Town Center at Warden and Highway 7. We also have amenities of ample street-level and underground parking, a pharmacy and a laboratory.
We recognize that choosing a pediatrician is an important decision for parents. We thank you for the opportunity to serve you and to be part of your family life.
