Lisa has been great to work with! She has helped me through a couple of different items and has always delivered an exceptional experience. She clearly answers any questions I have and lays out the options. Would highly recommend working with Lisa and her team at Redstone!

Alex Ellman is a common sense, detail-oriented, and knowledgeable business and estate planning attorney. As an in-house attorney, I hired Alex to represent my corporate client in contract dispute and general contract drafting projects. He provided such valuable advice that some of the company's executives hired him to represent them in their personal matters. I've recommended Alex to numerous people and businesses, and everyone has been very pleased with Alex and his excellent work product.

Alex Ellman was so thorough with our estate plan. He explains everything so well. My mind is at ease knowing that my estate plan is strategic, organized and well thought out. He makes the uncomfortable topics to talk about comfortable. I would highly recommend Alex Ellman at Redstone Law Firm.

I was unexpectedly involved in a precarious real estate situation that Lisa and Zach handled with ease. Zach guided and protected my family and finances through consistent and well-thought-out strategy to a successful outcome. I highly recommend them.
