Wow, that's really cool. You have a talent. It's very ascetically appealing. Here are a few things I noticed:
As a child Sherry would bath, dry and help with the dogs at her Mothers shop every chance she had.
I think that should be bathe.
Her and her family moved to Santa Clarita in 2008 when sherry started grooming neighbors and other dogs in the area at home.
I think that should be "SHE and her family".
Sherry should be capitalized.
The dogs she was grooming at home were becoming more and more.
This needs to be rephrased. Perhaps: She continued to groom more and more dogs at home.
Doing Dog Grooming has been an on going part of Sherry's life for most of her life and it's something that was never taken lightly
Get rid of the "Doing"
Always aiming to be the best and has had great success doing so!
Not a sentence. Needs a subject: SHE is always....
Don't have time to look at the whole thing right now, but those are a few things I noticed.
