The sentence is a headline for a digital ad and I'm not sure the tenses are correct [closed]
Since 1902, we are looking out for you.
According to this source - https://www.ef.com/ca/english-resources/english-grammar/present-perfect-and/ - "since" can only be used with perfect tenses.
Since this is in the category of "actions or events that have been completed or have happened in a period of time up to now" (https://dictionary.cambridge.org/us/dictionary/english/present-perfect), you should use the present perfect. So:
"Since 1902, we have been looking out for you."
Or
"Since 1902, we have looked out for you."
I believe either would be grammatically correct. Good luck!
