Wonderful Lawyer
Thanks to Greg, I finally received my permanent residency!! When we first filed my case a couple years ago I thought it was going to be a stressful and overwhelming process, but I never got that feeling knowing Greg had my back. He is organized, punctual, and always called/emailed to give me updates on my case. Thank you, Gregory S. Duncan, for changing my life!

Great Attorney
I needed a probate lawyer in the Oceanside, CA area. After reading the reviews from a lot of the websites that review lawyers, I hired Gregory Duncan. I am extremely happy with my choice. My sister had passed and Greg’s hard work and guidance was fundamental in getting through the hurdles of probate court, and closing getting her estate. He is easy to work with, very likable, and his availability was very good. If he said he was going to do something, he did it. I give him a rating of five stars.

Great lawyer!
Greg helped me with my parents' probate. It went smoother than I thought. Greg was very good about keeping me updated with what was going on and answered all my questions in a timely manner. I had contacted a few lawyers before choosing him, and I'm very glad he stood out and became my lawyer. I highly recommend him. I will be working with him on other matters in the future.

My husband and I worked with Greg to establish a family Trust. It was truly a pleasure working with Greg, I felt like I’ve known him forever. He is extremely knowledgeable, professional, and personable. Greg addressed every scenario of concern I had in making sure my family was taken care of if something were to happen. We felt comfortable and reassured throughout the entire process. He was attentive, thorough, and very easy to talk to. I highly recommend his services.

Great lawyer!
My experience with Greg Duncan was very positive. From our first meeting to becoming a US citizen he was a pleasure to work with. My case was complicated and very stressful for me but Greg’s confidence and calm demeanor put me at ease. He’s very responsive and never rushed me. He took time to go over every detail of my case. He is professional but also friendly and personable. I highly recommend his immigration services and would use him again.

Living Trust
Greg took care of my wife and I living trust. He was very personable , clear and concise, always returned phone calls and emails promptly. He dispelled the image of the arrogant lawyer just trying to pa D his billable hours. Very fair on price.

I am so glad I came to Gregory Duncan. My husband and I had previously contacted a different attorney who wasn't much help and took her time starting my permanent residency process. We decided to come to Mr. Duncan due to his excellent online reviews. He personally returned our calls almost immediately and was more than happy to answer any and ALL our questions before deciding. I am truly thankful to have found him, as he made this long tedious process very easy and manageable for us. He is very meticulous, organized, knowledgable, extremely polite, and personable. He will make himself available if need be and his rates are reasonable and fair. we payed for his service throughout my permanent residency process, meaning after he successfully completed a certain part of the process and filed documents we would pay him for that part only until the next set of documents were completed. He did not demand full upfront payment to assure us that the documentation submitted would be correct and his services would be successful. I would email him because I was nervous about the time frames and status during the whole process and he would calmly give me accurate explanations to my whys, whens, and hows. If you are looking for speedy responses, great representation and knowledge about naturalization, permanent residency, and other immigration needs, l highly recommend Gregory Duncan as your immigration Lawyer. We are so thankful to have had his help during this stressful process.

Amazing yet again!
Greg is a great attorney! I've used him for probate and recently bankruptcy. He's very professional but yet personable. His rates are great and he does all the hard stuff for you! It was simple, fast, and easy. One thing I love most about Greg is that he always keeps you updated through the process. Again he makes it so easy he does all the work and just updates you as needed. I've watched him in court and compared him to how other attorneys handled the same situation and he is just amazing! I was proud to have him on my side! I was nervous but he told me every single detail and what to expect and really made the whole process a lot less scary. I would recommend him to family and friends and I will always use Greg for any future issues I may need him for!

I needed to hire a probate attorney after my brother passed away. I was fortunate enough to find Greg Duncan. The probate case was going to be difficult and long. Greg handled the case with true professionalism and was very knowledgeable regarding probate law. I would recommend Greg to anyone who is looking for a probate attorney. I have since hired Greg for another case involving family law again he came through. Thanks Greg.

Very Pleased
Greg helped me with a probate case after my grandfather left me the executor of his estate. It was a difficult time for my family and I. Greg was very personable, understanding, and ready to help walk me though the difficulties following the death of a loved one and complicated family drama that comes along with it. There were defiantly some difficult times for me and Greg went above and beyond to make them as easy as possible. He is a great person and runs a very efficient law office. Greg will keep you updated on all matters and is always willing to answer your questions and hear your concerns. I would defiantly recommend him to anyone.

I'd would recommend Gregory S. Duncan to everyone!
Greg help me with my divorce. He was knowledgable and responsive whenever I needed his input. Everything went smoothly and his services didn't break the bank! A year later and we are still in contact, if I need something or just a simple question answered, Greg is always available! I only wish I'd have used him for my financial matter, it would have made things soooo much easier.

I Highly Recommend Gregory Duncan...
I did my bankruptcy with the Law Offices of Gregory Duncan. My experience was excellent. He explained the laws in terms that I could understand. He charged a fair rate, lower than other lawyers that I looked into using. He was kind, efficient, and got me the clean fresh start that I needed! I would recommend this office to anyone!
