Seeing others in heaven

Is it true that Catholics go to a separate place in heaven and those who are not Catholic will not see them?

All people who trust in Jesus Christ as their only Savior from sin, regardless of which visible church they were a part of during their earthly lives, will be in the presence of God in heaven and will see each other (Mark 16:16).

The Bible teaches that there are only two places where people will spend eternity: heaven or hell. Revelation chapters 20 through 22 describe those places.
