I should have written this review a year or so ago. Better late than never. I'd rather not go into details, but I was in the hospital, very ill, and no one seemed to know what was the matter. The ER doctor called in Dr. Guendert, telling me that if anyone would know, it would be her. I was admitted to inpatient from the ER on a Wednesday evening and she was there for me on Thursday morning. She told me I had one of 2 diseases, took a biopsy, and prescribed meds. I was in the hospital for 2 days. A few days later she had the results (she was correct) and phoned me. I had an office visit that week and she arranged for the doctors I would be needing. About a year later, another biopsy was needed, requested by my specialist, knowing it would be so much easier for me to get it done in Lodi instead of Sacramento. The appointment maker wanted to set up the appointment weeks later, but I asked her to please contact Dr. Guendert. She did, and the doctor had me come in the next day! Top-notch doctor -- staff, too! read more
