No matter how much i say about this Great and compassionate person who happens to be a doctor. I just had a chance to see Dr Greenberg for my sons’ circumsicion. I cant believe that such kind people do exist in this world who take pride in taking genuine care for human beings. I wish if he was accepting new patients.

Great Doctor! he cured me of an opiate addiction, after the first visit. always on time,respectful, treats you like an equal, and actually cured me of my fear of doctors! super,cool Doctor. Highly recommend him!—Steve Brown(Brampton)

ONE OF THE BEST DOCTORS IN TORONTO.very knowlegeable, very professional, great person, great doctor!  

AWESOME DOCTOR!!!! I cannot say enough good things about him. I had become dependent on oxycontin and he has helped me trememndously. I have been through A LOT in the last year: an abusive relationship, dx’d with spinal stenosis, etc. He has been INCREDIBLY patient with me and my ups and downs and has never given up on me. He has a wicked sense of humor, a heart of gold and what really got me was the first time I ever called his office he got on the phone and spoke to me personally!! How often does a doctor ever do that? If you have a problem with addiction forget the OATC, they are awful. Instead see this doctor and you will be so happy you did. I travel all the way from up north to see him and will continue to do so until I taper from suboxone completely. He’s an amazing doctor and I’d highly recommend him to anyone wanting to rid themselves of any dependencies. —Jodie

Doc G, he saved my life, when no other doctor listened to me, took me seriously, or gave a crap, THIS DR CARES for not only me, HUMAN BEINGS.. YOU ARE NOT A NUMBER AND HE IS APPROACHABLE, EASY TO TALK TO AND HE HAS A SENSE OF HUMOR… HE WONT MAKE YOU FEEL LIKE HES THE DR AND YOU ARE JUST THIS PERSON TO RUSH OUT OF HIS OFFICE. TRY TO GET THIS DR… he will help yoou when no one else will because he is committed to what he went to school for, and he takes pride in seein you get well. thanks dr. greenberg. we all think your great so i am really talking for several of your patients as well, that is why i know your reputation.. people talk in the waiting room,, if you have a problem with your doctor just ask other patients and see whats the deal… i have had 3 doctors of horror until dr.g. 

This wonderful doctor returned my intial phone call within 15 minutes and saw me as a new patient within 48 hours of that same phone call. He diagnosed and began treatment on that initial visit and frankly saved my life 

I have been with DR Mark Greenberg For several years and have not found in my 49 years of being alive a finer more peofessional caring Doctor he has helped me and seveal of my associates with addictions and family medical care, and is very understanding when it comes to your concerns, he keeps a very tight ship and has the heart of a angel when it comes to making the right decisions for our needs, If all Doctors followed his leed we would be in the best hands in all the world,my wife is a Legel assistant and I a equipment engineer and when it comes to threading a needle threw a microscopic hole there is no other Doctor we would have at the Helm but Mr Mark Greenburg. Bless him greatly!!! #1 

When we found out we were having a boy my husband and I immediately knew that we wanted Dr. Greenberg to perform his Brit Mila. Dr Greenberg has become the resident Mohel for our family as he has now performed our son’s Bris as well as our two sets of nephews on both sides of the family. Thanks for everything!  We recommend Dr. Greenberg to anyone looking for a professional and compassionate mohel.
