Hendon, who is the new development coach at Upton Park, wants to help out Gills boss Andy Hessenthaler, a man he credits for helping to restore his passion for the game.
"Andy brought a team over to West Ham for a closed-doors game the other day," Hendon told BBC Radio Kent. "I wouldn't hesitate in putting players Gillingham's way.
"I came to Gillingham, worked with Andy - who I not only respect as a manager but as a friend - and I've gone there and been revitalised. I look forward to training and matches now.
"I had a great working relationship with Andy and Nicky Southall - who I'm sure is going to relish his opportunity and step up to the plate now I've gone.
"I know Gillingham are in good hands."
