Attorney Kyle Fahey handled our matter with skill and professionalism, and was always responsive. 10/10, would work with him and the firm again.

The peace of mind that Peck Ricthey's office has given me is worth every penny. The services they provided me and my family in an emergency medical situation is beyond outstanding. Last minute notice, Peter Brady and team were compassionate, understanding and most importantly efficient and got the job done. Look no further if you have any needs that this office can provide for you. Definitely in good hands! Thank you, a thousand times over for all of your help.

I solicited Peck Ritchey, LLC for assistance with a living trust for which I became the beneficiary. I needed assistance with understanding the details of how it all worked. However, I was especially concerned because there were threats of allegations made by family members and a lawsuit was filed against me. I needed a solid professional who had my best interests in mind. Peter Brady took my case and he managed it flawlessly. He explained everything in a way I could understand, he knew the law inside and out, he was always available to answer questions, and even offer support when things seemed like they could become extremely problematic. In addition to this, he had a plan. He navigated the course as if he already knew the next move by the opposing attorney. He made me feel like everything was in control and that’s because he knew exactly what he was doing and he consulted with me about everything. We ended up settling out of court and ultimately the court officially dismissed the lawsuit. I honestly believe if it wasn’t for Peter and his expertise this could have gone in an entirely different direction. Peter did a stellar job and I couldn’t be more pleased and impressed with his performance.

Tim Ritchey is as smart, honest, and genuine as they come. He truly puts helping people above making money. If you have a need, don’t hesitate to hire him.
