Dr. Demers saved my life 15 years ago, I came into McMaster with horrible chest pain, fortunately I worked for one of the depts part time on call at the time, one
Of the staff drove me over, after all the required tests and information, they called Dr. Demers, fortunately for me she was there at that time, she just looked into my eyes, you are having a heart attack, sent me immediately to the General hospital, 2 stints, with 98% blockage , after7 years one more stint. To this date she monitors me in person every 3 months in the beginning and now every six months, I had a lot of rejection from the stints in the beginning, but perservance from the doctor figured me out. Today I am blessed to have and know her and I know she will be with me all the way, I was 65 at the time now 80, all the best to everyone she looks after, the absolute best. Sharon Robinson

I’ve been seeing Dr Demers for 4 years and she has been with me every step of the way. I’m a ‘complex’ as she refers to my heart and Dr Demers is the reason I’m still here. Great doctor, good with explaining things and never feel rushed
