That's not really true. Scripture does imply, a single overseer for a local church. Which agrees with the fact that Jesus Christ is the single head of the Universal Church.
1Ti 3:1 πιστος ο λογος ει τις επισκοπης ορεγεται καλου εργου επιθυμει
Faithful is the saying, If a man seeks the office of a bishop, he desires a good work.
This office is "singular" in the Greek. One man - not men, as contrasted with those who would be Deacons or Servants of the church.
The Greek word: επισκοπης is literally translated: "episcopate". However, it comes from a Greek word that means "to watch" or "to go see". Therefore, an "Overseer".
In the letter to Timothy, it is always mentioned in the singular... just one man:
v.1 ".. If a man..." - .."he desires..."
v.2 "The Bishop (Overseer) must be a husband of one wife..."
v.4 "one who rules his house..."
v.5 "But if a man knows not how to rule his house, how shall he take care of the house of God?"
Additionally, these same instructions are given to Titus:
Tit 1:5 For this cause left I thee in Crete, that thou shouldest set in order the things that were wanting, and appoint elders in every city, as I gave thee charge;
Note here - that Titus was to appoint "elders" in every city, not "elders" (plural) to every church but in every city. After this, the instructions are the same as given in 1 Timothy:
Tit 1:7 For the bishop must be blameless, as God's steward; not self-willed, not soon angry, no brawler, no striker, not greedy of filthy lucre;
Tit 1:8 but given to hospitality, a lover of good, sober-minded, just, holy, self-controlled;
Tit 1:9 holding to the faithful word which is according to the teaching, that he may be able both to exhort in the sound doctrine, and to convict the gainsayers.
