I truly enjoy taking care of my patients. I believe the foundation of the patient-physician relationship is to always put the patient first by listening carefully and engaging in a care plan as a team.

I was very satisfied with my Doctor's advice. By Looking at me she knew I needed a couple days off from work, I appreciated that she did that, without me asking her for it.

Dr. MacKinnon seems to have a steel trap mind. Even before she opens my records she starts to speak to me about my health issues. She recalls, small specific details that other Doctors easily forget. This ability really personalizes the treatment that I receive and strengthens my trust in her diagnosis and treatment plans for me.

This was my first visit with this provider and it was very positive.
Feb. 26, 2020
Dr. MacKinnon was amazing! She got to the bottom of my health concerns and seemed generally interested in my wellbeing.
Feb. 23, 2020
I went to the doctor for a follow up visit and the doctor came in the room for about 2-5 minutes! Increases my dosage on my meds after I expressed how one of the meds has me breaking out in hives and itching. Not happy with the way Dr. Mckinon told me she would be right back but her MA walked in 5 mins later to tell me my final instructions. Totally not satisfied, busy looking for another doctor asap.
Feb. 18, 2020
appreciated that I could see my PCP on short notice vs another provider. Initially I was told There may be a 45 minute wait but there wasn't so that was extra nice.
Feb. 12, 2020
she is an excellent listener and has excellent bedside manners. I fell very comfortable with her.
Feb. 5, 2020
Dr. McKinnon is an excellent provider and listens to what I have to say. She is professional and kind.
Jan. 24, 2020
Dr. Mackinnon demonstrates a high degree of compassion and empathy.
Jan. 23, 2020
I felt Dr is on clinic schedule & length of time she can spend with me is predetermined. I had other things I wanted to discuss but ran out of time Disappointing.
Jan. 21, 2020
not all issues were addressed and felt a little rushed.
Jan. 16, 2020
Dr MacKinnon was outstanding, probably the best provider I have seen in decades.
Jan. 7, 2020
Dr. MacKinnon is always caring, listens to my health concerns and is an excellent diagnostician. she always takes as much time as I need and explains everything about my health to me. I feel blessed to have her as my family dr.
Nov. 13, 2019
She brings up sensitive topics and offers advice without making me feel bad about myself or make me feel like I'm doing something wrong. I've had providers do this in the past so I really appreciate that.
Nov. 3, 2019
She listen to my concerns, and help get me the proper medication
Oct. 21, 2019
I think a phone call about lab results is nicer than looking up results in Mychart. Then there is a chance to ask questions.
Oct. 10, 2019
Dr. Mackinnon took the time to sit down and talk with me about several concerns. She demonstrated compassion and empathy. In addition she explained things to me in a way I could understand. She is an excellent clinician.
Oct. 9, 2019
Good listener: patient, concerned, thorough in presenting options
Oct. 7, 2019
reply to my chart has not been as prompt as other physicians. otherwise very good experience. I am thankful for alll the time that dr. Mckinnon spent with me.
Oct. 3, 2019
At the end of my appointment, my provider asked me to wait in the room for my 'paperwork' before I left. I waited over 15 min and no one came back to the room and I couldn't find anyone in the hallway or at the front desk. So I left. I dont know if this was a mistake/fluke, but it certainly was bizarre!
Sept. 29, 2019
Everytime I visit Dr MacKinnon I feel well cared for and treated with dignaty and respect.
Sept. 26, 2019
I had to wait a whole month before I could see the doctor for the issue / problem I had. I did'nt get any help /medication for that specific problem.
Aug. 5, 2019
Dr. Mackinnon always provides the best care when I see her. I am an active user of mychart. Dr.Mackinnon and her team answer my mychart needs in a very timely manner, including helping to get referral appts/tests and giving me my test results.

Provider is wonderful. Concern with being scheduled at 7:45 for appointment to arrive to a closed check in desk and along with 4 other patients. Then being told that 7:45 is our check-in time for an 8:00 appointment. The timing is of little importance, but rather, the check-in desk should be open at 7:30 as many patients arrive early to check in and not aware that time is already built into their visit. Also, I updated all of my information in MyChart prior to arriving so that it would expedite the visit and not have to review all the information. This was not effective as I was still asked all the same questions. Physician and staff are wonderful, system/policies seem to be off.
