I received the same identical call as described above.  I am not in a doctor's office so wasn't even sure what imaging they were talking about.  I appreciate the other people who took the time to write about their experience with this caller.

I just received the same phone call. We are a Chiropractic Health and Wellness Center. It seemed suspicious to me as well.

Same "Marty Allen" call as above.  Sounded suspicious.  Thanks for the info.

Howard called today with Dr. Scott Davis. Wanted to speak to my doctor. Hesitated to leave a msg. Sounded like a sales call when asked the nature of the call. Answer- diagnostic testing. Gave me this number.

Same problem as the others.  6+ years ago, my phone number belonged to a physician.  I've been getting telemarketing calls all along, because the people who buy and sell directory information are lazy and negligent. Tweeting 404-474-7710 to #TELETRASH
