Dr. Shirley Ha is an incredible person and Doctor. She has helped me in so many ways that go beyond my visual system. I cannot recommend her enough. Her clinic is organized, clean and welcoming (also, ample parking - hard to find these days!). I had a wonderful experience as a patient in her vision therapy program. Thank you to the A-Ha Vision team!

I have been a patient of Dr. Shirley Ha for many years and can recommend her with confidence. She is extremely professional and courteous in her demeanor, as well as very knowledgeable. Dr. Ha is well informed and helpful with any questions or concerns you may have. You just cannot find better eye health care anywhere.

This is my first review and i need to tell everyone who might need help to decide which doctor to chose. Dr. Shirley Ha is an excellent doctor, her knowledge is beyond any other doctor i met, she is really honest and she is trying to help you as much as she can. My first appointment was for 50 Min, but doctor Ha spent with me more than 2 hour to see what is wrong with me. She is first doctor to understand my symptoms and i am really happy and privileged to be able to see her. If you have problem with the balance she is doctor to visit. Thank you Dr. Ha

Dr Ha and Pamela have been terrific in guiding me through a vision therapy program as part of my post-concussion journey. They are generous with their time, passionate about what they do, and highly intelligent. I feel very fortunate to be under their care.

I first came to Dr. Ha in early 2020 for rehabilitation related to a concussion I sustained a year earlier. I had done other therapies and rest but couldn't get back to being the competitive athlete I am. Dr. Shirley Ha did a thorough assessment, and her amazing team worked with me step by step allowing me to get back to competing on the international stage. I would recommend this therapy/rehab to anyone suffering from a concussion and anyone with vision related difficulties. Caring, professional, extremely knowledgeable. Cannot thank them enough!!

I have been a patient of Dr. Ha since 2000 and all my family are patients too. Dr. Ha is very detailed, knowledgeable and trustworthy and she has gained our confidence over the years. At one time Dr. moved her office to St. Catharines Ontario and I still went to see her even though we live in Oakville Ontario. I would without any hesitation recommend Dr. Ha to take care of your vision needs.
