Dr MacKinnon was very thorough. She appeared very knowlegable. I appreciated the time she took with me.
The medical assistant I had was wonderful. She was knowledgeable about the system researched my questions and informed the physician of my concerns so they could be addressed. She picked up that I had not heard what she had said and immediately inquired whether I had a hearing loss. Dry perceptive and helpful for her to know if she needed to speak a bit louder. Yes I do have a hearing loss and had not put my hearing aids in. Kudos for her. Please let her know of my respect for her and share with her supervisor.
