Infusion Reps!

Hi,

I accepted a job as an infusion rep recently . I am pretty new to the industry and could use any pointers /advice . My company has infusion centers and I am to get doctors and their MAs to refer their patients to our infusion center. I have been bringing snacks and the likes to the MA and had small success with that . Should I be focusing my energy meeting with the doctors or are the MAs my best bet? It seems like my biggest competition are the home infusion reps . Any advice would be appreciated!
