Highly recommend
After having to go through a personal injury accident, I am so grateful William Lalor was recommended to me. He was not only thorough and on top of everything, he showed compassion and empathy throughout the whole process. He put my well-being and best interests first. Not only did he make going through this easier on me, with his meticulous work on my case, I was able to receive a settlement in my favor.

First-time Home Buyer, Co-op (Westchester, NY)
I partnered with WPL & Associates to help me navigate my first-ever home purchase. The unit being a co-op meant that the process was much more involved - there was a board & maintenance company - in addition to the seller (and the seller's team)! Throughout the entire process, WPL & Associates were great to work with - supportive, thorough, responsive, and as dedicated to my sale as I was. From reading the contracts, to the lien search, to providing advice, and guiding me through the closing, the team was stellar to work with! They'll tell it to you straight, and even better, in laymen's terms (oh, I had no idea about the jargon of real estate and mortgage financing)! I will definitely work with them again.

Bill was engaged with my team on a complex case that extended for several years.

In addition throughout our case Bill's investigation, explanations and communication were excellent. I feel very comfortable recommending Bill.

Highly recommended!
I highly recommend Mr. Lalor. He handled a sensitive employment-related issue with great success. He is a pleasure to deal with, communicates clearly, and is thorough in his research and analysis of options for his clients. We were impressed with how he was on top of the issue, regularly following-up, so we never felt as if we were forgotten or on the backburner. It was clear that our case got the attention necessary.

Fine Job
Bill did an outstanding job for me! Bill is very easy to work with and was always available whenever I had questions. He did an thorough job researching the background of my case and is very detail oriented. He kept me informed with regular updates as the case progressed. I was extremely well prepared and confident for my deposition. Bill’s hard work and dogged preparation were critical to a successful outcome of my case. Thank-you Bill!
