Trombone Repair Techs in Southern Indiana?

[SirJohn]

Wondering who has recommendations for a tech in Southern Indiana. Not an immediate need, but for future reference. I've concluded based on the repair jobs I've seen on the high school horns by the guys in town that I would not want to use them. I did find out that the Jacobs School sends their low brass to Martin Wilk and he is highly recommended by a lot of tuba and euph guys, but I don't see much about him for trombone. Anyone have experience.

Is there anyone that is well known and recommended for trombone in the general Indianapolis area and the southern half of the state?
