I would NOT send things there for Gracie. She has NOT trained there for many years and lives far from there. The best would be to try to figure out the rink she actually trains at in California. When sending to a club/rink, it is only a good idea if it's the current club/rink.
These OP asked about her figure skating club and that is her club. Whenever they announce her at competitions in the US that is the club that she represents and that is the club listed for her with ISU. So, if you something to her there it will reach her. But here is the training spot for Gracie
She trains at
Toyota Center
555 N Nash St
El Segundo, CA 90245
