What is the difference between the Trinitarian concept of God and the Mormon concept of God? Just curious. Hope I can get helpful feed back.
In Wikipedia page, Christian Denomination, we see Mormonism as a Nontrinitarian Denomination. Explaining that:


  Mormons see themselves as believing in a Godhead comprising the
  Father, Son, and Holy Ghost as separate personages united in purpose.


On a separate page, God in Mormonism, explains that The Father in the Godhead is the same Jewish God, Elohim that we know.

Basically, unlike the trinity, most Mormons believe that:


  the Father, the Son, and the Holy Ghost are not said to be one in
  substance or essence; instead, they remain three separate beings, or
  personages, completely united in will and purpose as one God
