About CVPD

At CVPD, we are passionate about helping people with their breathing difficulties.

Patients will be asked by our respiratory therapists to perform a series of breathing tests. By using the information gathered at CVPD, along with the patient’s other medically significant information, physicians can determine how efficiently their patient’s lungs are working, and ultimately determine how to move forward with any necessary treatments.

Our Values

Patient Care, Comfort & Respect




Efficiency & Professionalism

David G.
Growing up David always loved biology. After completing a Biomedical Science Degree and Psychology Minor at the University of Waterloo he went on to Conestoga College to pursue a career in Respiratory Therapy/Pulmonary Function.

David enjoys being a Pulmonary Function Technologist because he likes to challenge his patients to give their best effort. He finds it fascinating to see the differences between individuals, how the lungs can change over time, and how they can react to treatment.
