My appreciation!!
I had the pleasure of meeting Pieter O’Leary back in 2016 as part of the Porter Ranch gas leak lawsuit and have been interacting with him as a client since then. He is resourceful, conscientious and an excellent lawyer. His vast knowledge, professionalism, effective communication, timely response and good follow through makes him a great asset to his clients as well as the firm he belongs to. My heartfelt appreciation to you Pieter for everything you have done for me and my family.

Bathroom remodel nightmare
I have been going through a major remodel project. And got caught in between negligent workmanship issues, endless time lines (6 months!) and a lot of money spent. I consulted Pieter to help me through all these issues. He is very knowledgeable and has a great way of calming me down when I am about to lose my German temper. He outlined clearly what options I have but also which consequences to consider. Very professional, I highly recommend him! Vielen Dank Pieter, fuer deine Unterstuetzung!

Contract/Negligence Lawsuit
Pieter was instrumental in bringing this overly-long suit to completion. I sat through several mediation sessions, was deposed, and worked closely with Pieter to gather documents relevant to our case. His attention to detail, his willingness to respond to any and all questions/concerns in a timely manner, and his genuine concern for our community made a difficult experience more satisfying. Our community is now in a position to go forward and attend to other important issues without having this lawsuit hanging over our head.

Mr. O'Leary helped me and my family solve legal problems and contract issues. He reviewed the contracts and provided advice so we could successfully handle the problems ourselves and saved us time and money. He looked into the issues and gave us valuable and useful information. Everything turned out very well and got resolved fast, We highly recommend Mr. O'Leary, he is very knowledgeable, helpful and professional.

Good Representation results with Excellent Outcome
Pieter and his firm represented our homeowners association in a lawsuit against the various companies involved in a community wide major renovation project valued at nearly 2 million dollars. It was a difficult and complex case with many depositions and several mediation sessions. Pieter handled the case from beginning to end, attended all depositions, met with expert witnesses and vigorously pursed all avenues of recovery. Pieter was always available to discuss the case or respond to questions. The Board of Directors was very pleased with the recovery he helped obtain. They did what they said they would do.

Went above and beyond in support of a contract dispute
I needed a local California attorney to handle a five-figure personal services contract dispute for me. Pieter fit the bill perfectly. He researched the disputed issues and parties, provided me with various options and gave me all the information I needed to make the decision to arbitrate or litigate. Pieter went above and beyond what I expected and strongly recommend him to anyone with a contract dispute. Whether your case is going to be arbitrated or litigated, Pieter is your man!

Pieter M O'Leary
Pieter provided a clear path of action early on. It helped because this was the first suit I was involved with. At time of deposition, he prepared me for the types of questions that would be asked. It helped a lot because the other lawyer was trying to intimidate me into admitting things for his benefit. At the time of settlement, he gave us a good idea of what would be a reasonable amount, given that we really didn't want to stretch the ordeal out if we didn't have to. I believe he gave competent, well-informed service and was available for questions which was important to our success because we were first-time plaintiffs.

A fine attorney
Pieter is a fine attorney who is always available to help. He has assisted me with several legal issues, including a class action lawsuit in federal court. I have also recommended Pieter to my friends and know they appreciated the free consultation and the legal help. If Pieter can’t help you, he will work hard to give you the names of people who will try.
