    Sheila,

     

    It is a Swedish whitebeam (Sorbus x intermedia) or a related cultivar.

    http://en.wikipedia.org/wiki/Sorbus_intermedia

    Yes, it should have berries in the autumn (normally red).

     

    The foliage looks healthy enough (colour, turgidity, etc.). The scars over the pruned-off branches are also good (good to see the branches were not sawn off too close to the trunk).

    But the cracks in the bark and the dead/damaged branches are not a good sign. Sorbus are susceptible to various pathogens, such as bacterial canker. But the cracks, and maybe the problem branches if associated, could hint at wind damage or root damage (perhaps due to excavation or overcompaction). One would like to carefully slice into the cut to see what's going on; looking for gumming, staining, etc. If it was not for the good condition of the foliage, I would suspect it may have silverleaf (a disease more commonly associated with Prunus species). If so, it would be unlikely to recover, though it may take a year or two to die.
