Although I was offered a welcome visit where I was promised that I would not need to make a decision in joining, I did feel a bit pressured to join. I was asked for my signatures to released my medical records from my current Primary physician- felt very hurried/rushed for paper work, and NO- I am definitely not interested in joining this provider.
