I am the parent of two children. Both my children were troubled and life was challenging, to say the least, for several decades. I have a website devoted to parenting of troubled teens.

Check it out! I'd be happy to pass along wisdom I've gained in the 20+ years of parenting troubled children. You can email me at:
Best of luck to all of you!
