I, too, had TIAC coverage but when I received my quote for renewal, it increased considerably (and I have never had a claim!)  Someone mentioned Alliance Marketing and Insurance Services (Bill West) recently so I contacted them as well as three other insurance companies. I found AMIS rate to be extremely reasonable and their professionalism top notch. They followed up with questions I had on a very timely manner!  I highly recommend consider contacting them for an     E & O quote when you are shopping for new insurance.
