Hump in concrete after foundation repair

[Zane Paul]

I had the slab jacked up and piers installed. Guy did an A++ job, the old cracks in the wall fit like they're zippered. 

But in the master bedroom there was a small problem and the subfloor buckled, so there's a spot about 2.5ft by 8 inches that's bulged about 1/4 inch. The piers there were doubled up to the sides so it's not going to be an ongoing issue.

I'm planning on laying the tongue in groove laminate but I need to address this first, obviously. What are my options for leveling it out? 

This is my first rehab and I'm not really sure what would be best. I don't really want to use self leveler since it's directly to the side of a doorway, so I think any slight grading would still be detectable and possibly become a trip hazard. Is it possible to just grind it down? The slab itself is about 8" thick so I don't think 1/4" inch should be a problem but I'm not sure.

Any other ideas?

Thanks for your time
