Hello,
I was recently at a workshop where I met Dr. Lee Klinger (www.suddenoaklife.org). I was amazed with his experience as a researcher and now dedicated practitioner of healing our native oak trees of sudden oak death.
He has many years now of experience in treating oaks with great success.
He works all over California doing this work.
If you are having issues with your oak tress I would highly highly recommend Lee.
Check him out on-line:

see for yourself his results.
sincerely,
Michael Cutburth
