Mohammad was extremely friendly and professional!  Handy as a company is VERY thorough in their communications.  Unfortunately, after the installer left, it was dark and late.  The next day, we noticed to bolts were missing from the top bunk that were main supports and the mattress support rails were not installed.  He left the support handles, but none of the extra hardware, so I was unable to install myself without having to go to Lowe's and purchase extra (which was very difficult because they didn't have the exact sizes).  I tried to call the installer direct and he never returned my call.  Sad.
