My current RE's office would not let me see another RE in the same office while my RE was out on mat leave. Which is such an inconvenience! If I wanted to see another RE in the same office, I would have to see them 'as a new patient' and I had to specifically state I wanted a second opinion.
My new RE has one other RE in his office and they have similar methods of treatment, so they will cover for each other if they need to.
Curious what your experience was/is?
