Alliance and the Sparrow labs in our offices will be closed in the afternoon of March 20, 2019 to allow for employee education.  The Mason office will close at 11:00 am with the lab closed all day. The East Lansing office & lab will be closing at 11:30 am. Normal business hours will resume the following day.
Alliance is offering Bone Mass Density screenings on April 18 and May 29.  These quick & simple preliminary screenings measure the bone density in your heel and help determine your risk for osteoporosis. This screening is for women who are over 35, are not pregnant, and have never had a bone scan.  Cost is only $10.
Please call the office to schedule your after clinic hours appointment.
