No.
It is very difficult to take direction from a CA that has never used a chainsaw, tied a knot, or been able to understand the dynamics of a tree.
Any tree.
These CA certs that were really important/a prize, to me 10 -15 years ago, are now being handed out in classrooms (collage)
, and Boy Scout Troops.
To be an ISA Certified Arborist is only about sending in the money, getting a test date, passing the test, and then, "hanging out your shingle."
There is no way anyone can prove this wrong.
As professionals, paying lots of money to the ISA so we can call ourselves a Certified Arborist is a waste.
My next door neighbors step son is a CA.
19 years old. Never used a chainsaw in his life.
I know;when he helps me on side jobs no matter what he will not use a saw.
