I had an extremely high conflict and extremely complex divorce case involving multiple courts and jurisdictions. Stephen Gassner provided excellent support and analysis and went above and beyond to ensure the best possible outcome of this case. Highly recommend.

I had a difficult and very contentious case that involved custody across state lines. Stephen Gassner provided exemplary representation which greatly mitigated the extent of the litigation, keeping my kids best interest at the forefront of the proceedings.

Hired Attorney

Shop around before you settle for this crook, he will literally drain your pockets and expect you to keep paying to retain his services. He doesn’t work on any case. His paralegals do all the work (if they even work on your file) and he will show up to court late and unprepared. I find it very unethical how he replies to reviews exposing personal life or case matters, unethical! Office is filthy unorganized and has clients files laying on the floor with personal information exposed.
