Report
I decided in the middle of my case to switch law firms because the lawyer i had wasn't treating my case like a priority. My mother told me about Mass Tsang and that was the best decision i ever made. I felt alone going through my case but as soon as i walked in the office the atmosphere made me feel safe. Alexei was my lawyer and he made sure to get my charges withdrawn DAYS before my trial. He is an amazing lawyer that digs deep and tried to understand me as a client and made sure to reassure me that the end of the road would be success. Alexei, I thank you so much for beating my case effortlessly

I was referred to Mass Tsang by family and was fortunate enough to be put into contact with Hugh Everett. From beginning to end he was a great help and worked towards making me feel comfortable and was very honest with the procedures of my case. During my trial I was incredibly impressed with the amount of work and thought he put into every argument he brought before the court. I couldnt be more grateful for his efforts and would highly recommend for anybody who may ever need a lawyer.

Alexei Zaitsev helped me with my case. He was incredibly professional and helped me with every step of the way. He took a lot of care in preparing me for the trial and answered any questions i had. He would always find time for me throughout the week to go through mock trials and made sure i was absolutely prepared. At first the case seemed hopeless with everything stacked up against me, but when it came down to it Alexei really pulled through and won the case. I could not be more happy with the result and choosing Alexei as my lawyer.

I would like to say Alexei Zaitsev handled my case very professionally. He is really knowledgeable with the system and assured me that I had nothing to worry about during the whole process. Alexei showed me he was dedicated to win and it showed in the end. I am very grateful for Alexei Zaitsev because I am sure with any other criminal lawyer, I would not have had the same outcome.
