Jim Brady posted the following announcement about the Jim Brady Trio on March 14:

2015 was an incredible year. It’s been amazing to see how the Lord has blessed our first year in this new ministry! In many ways it was the greatest year with so many open doors and also the most difficult year as I said goodbye to my father and sister, just one month apart.
Now, we’re experiencing another unexpected turn. Tim Parton has resigned his position with the trio. While it was a surprise to us, it’s no surprise to our Heavenly Father. We know God is in the details, and we’re excited to see His plan unfold for us.
We wish Tim the best and ask for your prayers for him, as well as continued prayers and support for us as we seek a replacement.
We have asked our longtime friend, former Legacy Five member and Director of Operations at Song Garden Music, Gus Gaches, to fill in until a replacement is found. A big thank you to Song Garden for sharing Gus with us during this time of transition.
Melissa and I love and appreciate you all!
