Errata:
The parentheses around the max aggregate are not necessary.
A.next_contact now displays at the end of each returned row as 'infinity'.
Your subquery isn't doing anything to match on person_id, so it's going to match all the records with the highest next_contact in activities.
I think you want something more like:
A.next_contact = (select (max(A.next_contact)) from Activities as A2 WHERE A2.person_id=A.person_id)
Or, for that matter, since next_contact is all that you're drawing from activities, you can also just put it in the select:
select (P.person_id, P.lname, P.fname, P.direct_phone, O.org_name,
(select max(A.next_contact) from Activities as A WHERE p.person_id=A.person_id)
FROM ...
