5 Stars  I got called back on time, which is always appreciated. Dr. Fredenberg was very cordial and thorough during my screening, even noticing a minor scratch on my arm that my dog had given me two weeks ago. I had two minor procedures performed which only stung a little due to the adequate amount of local anesthetic. All in all, a very nice visit. –
