A lot of Strider's grooming I do myself. I keep his feet all trimmed and pretty, plus his brushing and bathing, teeth care, nails, etc.
The only thing I don't do with him is the thinning of hair in front of his ears. The woman who is mentoring me let me know I could really screw it up if I trimmed it wrong and it would take months to grow back so she does it instead and I watch and learn. Eventually I'll be skilled enough to do it myself.
One of my friends is an apprentice groomer, she is very skilled at rough collies, and learning borzoi with me. One of the things I love about her is she refuses to groom a breed until she learns EVERYTHING about how to do it right. Right now she is training on scottish terriers. Since none of the local groomers know how, a really good breeder is teaching her the right way so she can groom that breeder's dogs for show. Once a month I take Strider down and we bathe him using her nifty shampoo machine thingy and blow dry/train his hair with her good dryer. After our next borzoi I'm saving up for one.
Charlie is waaay easy. I brush him with the Mars Coat King to get dead undercoat out, and pretty much just pluck his ear hair. Which for some reason he loves.
There are some really sweet, caring and marvelous groomers out there. I know some of them and would trust them to groom Strider without any second thoughts. And then, there are some yucko ones who I would rather punch in the teeth than let touch my dog. I know one woman who is still grooming, who got fired from the last place because she punched a dog in the face and then shoved it off the grooming table when it wiggled too much as she was clipping nails. I don't think those groomers are the norm though, and you can avoid them by talking to their clients and seeing what their experiences are like.
