Palm Desert, CA |
Dr. Frei looked half asleep and acted accordingly throughout the entire evaluation. Was asked to bring all images, and provided a detailed sequential list of tests, results for her review. She took a cursory glance (2 seconds) at my paperwork and images. She stated "nebulous" concerns. And that there were no additional medical records or imaging studies available for her review (FALSE). Waited two months, spent $100 getting to LL to see her, waste of time and $'s. LL Standards not met.

I recently saw Dr. Frei and she did a very thorough neurological exam & initial intake. These days its hard to find a specialist who goes above and beyond the typical 15 minute doc-in-the-box visit! Dr. Frei is a knowledgeable and caring movement disorder specialist. I would recommend her.

I've been a patient of Dr. Frei's for years. She's very knowledgeable and cares about her patients. I've never had more than a 30 minute wait at Loma Linda but the prior office was horrible with scheduling and I often waited more than an hour.
Long Beach, CA |
We had one visit with her and she was three hours late. She then had a receptionist tell us she was in a meeting and to cancel our appointment. I demanded to see her and after seeing us for a few minutes she prescribed a medicine that was very contradictory for RP and would not listen to us. After the meeting we tried to set another appointment and were told DR Frei was not coming back to that practice again. This was before she showed up at her current job. She should be removed from practice.

Terrible experience. I had an 8:15 am appointment. While I was in the waiting room the staff were commenting that she was late again. She finally strolls in, 45 minutes after my appointment was ace filed. I waited another 20 minutes before I was called back and then another 40 minutes before I walked out. I am used to waiting for appointments, but being either the first or second of the day and waiting almost 2 hours is inexcusable.
