Does anybody know if PSG is a reputable card grading service? Thank you Cindy

PSA dominates the market. SGC and Beckett are reputable. GAI used to be. Most of the others have little or no credibility.

They may be a grading service but not high on the top three that everyone looks for (Bekket if black label > PSA > CGC).
