Dr. McNab is excellent. I only wish I had her in my life sooner. She listened, asked questions and took action for a treatment plan on the spot. I feel assured in the diagnosis and my treatment plan. I left feeling confident in her care and I look forward to our follow-up.

Really appreciate the hour that she spent with me. I think she is my favourite dr to date!

Dr McNab is exceedingly unprofessional. She is far too lazy and doesn’t provide competent endocrinology healthcare. She refuses to diagnose your diabetic Type. She doesn’t complete any treatment whatsoever. She doesn’t meet CPSA standards of care. Simply put she’s incompetent and shouldn’t be permitted to provide any health care on live patients. She’s going to kill some one yet. I’m surprised she hasn’t. Please run like hell if you see that your assigned endocrinologist is McNab at the UAH. She’s unable to provide assessments continuity of care and dumped my diabetic care on my gynaecologist. Heal thyself from your incompetence Doc. Please quit medicine to become a mortician or funeral director. You’re not even fit to treat dead cadavers. If you have had made a mistake about others care, make a complaint to CPSA.

Extremely full of herself. Was my doctor/ specialist for 5 plus years, wouldn’t listen when I told her my issues, said I’m fine, no matter what was wrong with me. I ended up at a fertility specialist who changed my medication for me and said I was living with post partum depression from the meds that McNabb had me on. She got another doctor to tag team bully me in one of our meetings. Then dropped me as a patient, did not refer me to a new specialist and refused to send over my medication to my family doctor. She’s quite a piece of work.

Her patient from Outpatient Diabetic Clinic at Royal Alex and she is totally awesome, friendly and has good listening ears. Highly knowledgeable and will break down the information required well for it to be understood. Highly recommended!

Let’s just say my diabetes has always been a struggle. The stollery would leave me crying, scared, and they didn’t help. I was so scared to go back to a specialist as I got older. Then I was referred to Tammy. Dr McNab cares about her patients on all levels! The nurses are absolutely amazing as well. They really take all concerns seriously. I was in emergency once and a few days later Dr. Mcnabs team had called to check in on me.

Dr. McNab is the most kind, caring and knowledgable physician out there. She genuinely cares about her patients and even takes the time to call you to see how you're doing. I've been so lucky she's taken me seriously, after having doctors pass me off for years. Any patient is lucky to have Dr. McNab!

Dr. McNab is very compassionate, friendly, knowledgeable, patient, understanding, thorough, genuine and overall an amazing doctor! Her prompt diagnosis and treatment plan have given me back my life. I am grateful to be in her care and trust her completely. The nurse and front end staff are not the friendliest, but I have spoken with Jennifer who was very nice.

Cares a lot about her patients. Always willing to listen and has fit me in at the last minute many times. She also works with an awesome nurse. I would highly recommend her.

By far the worst doctor I have ever encountered. Seemed overly confident in her herself and yet didn't get the right diagnosis, likley because she would not listen. Thankfully I was properly diagnosed and treated elsewhere.
