I am also from the Stockton area and was unaware of the EF being offered at St. Gertrude’s. I remember that it might have been at one time, but when we went to check, it had stopped. But I could be wrong…Do you know for certain it is still offered today?
Along the lines of the OP, I would say that in all my parish hopping aroudn this town, I haven’t found one NO Mass that is consistent. I currently attend St. Bernadette’s, as it is closest, and for the most part there is little tinkering. That being said, I went to St. Stephen’s in Sacramento for years, (was actually married by Rev. John Berg, the current Superior of the FSSP, back when he was the assistant priest and the Fraternity was still at St. Rose and Immaculate Conception parishes), and it was very spriritually fulfilling. Haven’t been to Sacramento for a while (1 to 1.5 years) as budget and wife’s class schedule are currently a strain.
It would be a wodnerful thing to get an FSSP Mass going in Stockton, but I have heard that Bishop Blaire is very much against the old Latin Rite. I was told by the Pastor at St. Bernadette’s that he would allow an EF mass if there was a “ground-swell” (his word) of desire among the laity for one. I didn’t know how to respond at the time (this was right after the Pope issued the clarification on the Motu Propio). Any thought’s suggestions on how to start up some sort of petition for an EF mass on a weekly basis in Stockton?
