I can’t overstate how grateful our family is for Leslie’s guidance through what was an incredibly difficult and emotional process. Our uncle passed away without a legally binding will, and by the time we found Leslie, the estate situation was already deeply complicated. We had spent more than two years trying to navigate probate without truly understanding what we were doing, and it quickly became clear that we needed expert help. Leslie stepped in with clarity, patience, and a calm confidence that immediately reassured us. She knew exactly what needed to be done, how to correct course, and how to move things forward properly. She also connected us with a trusted forensic CPA, which was invaluable in helping us make sense of a very complex financial picture. Throughout the process, Leslie led with intelligence, grace, and steady assurance. She was clear without being condescending, patient with questions, and consistently calm in moments that were understandably stressful. We genuinely could not have done this without her. If you are considering working with Leslie, know that you would be putting yourself in the hands of someone truly trustworthy, knowledgeable, and kind. She is a rare find and an exceptional attorney.

We just completed updating our trust documents with Leslie, and we are so happy we chose her to complete this task. We had a complicated and emotionally charged need to change our trusts. Leslie handled this job with kindness and sensitivity. She tackled the complicated nature of our situation with creativity, ingenuity, and enthusiasm which was essential to complete this job. We were so impressed with her ability to find solutions for a difficult legal dilemma. We are incredibly grateful for Leslie’s professionalism in helping us update our trusts. And to top it off, she is a lovely and engaging person and actually made this an enjoyable process. We wholeheartedly recommend Leslie for any estate/trust needs, whether simple or complicated. She is simply fantastic!

I would highly recommend Leslie Gammill to anyone dealing with Estate and/or Probate issues. She was efficient, supportive and extremely helpful in getting me, as an absentee executor, through the California probate process. She was a great communicator and thoroughly and effectively handled every aspect of the process often going above and beyond. She is a true professional, knows her stuff and will exceed your service expectations - a perfect attorney to have on your side for what can be a complicated process.

Working with Leslie Mark Gammill was great! She handled my Aunt's estate in California, while I live in Pennsylvania. She was on top of every aspect of finalizing and closing out my Aunt's estate after she passed away. I would recommend using her law practice.
