Need recommendation for brick oven mason in central NJ

[NJOven]

Bought a house last year which had a brick oven and, after several curing fires, the floor busted off a 3" by 3" chunk. If I had to guess, would guess residual steam as I heard a loud pop when it happened. Regardless, looking for a qualified mason familiar with brick oven work to assess, and repair or replace the floor.

Thanks
