"An attorney friend referred me to WLG saying it was the only employment law firm he recommends. From the beginning, my experience was very positive, and a favorable outcome was reached in a relatively brief timeframe.

He was always available, even after hours and on weekends to answer questions and provide well-considered advice which gave me peace of mind during the process. I highly recommend WLG to anyone in need of excellent counsel for employment matters."

Thanks Mark and Team for helping me through one of the most difficult situations I've ever encountered! Your service was prompt and I was appreciative that you were able to wrap things up so quickly. I am grateful to have been afforded the opportunity and regroup to figure out my next steps in life. I am now excited to head in a completely different direction than my former profession, and will be entering the field of real estate next week. Thanks again - I hope you are all well!
Beth PavnickLitigation Client
Mark Whitney served as primary employment law services provider at two financial institutions where I was CEO. Not only did he demonstrate proficiency in the law but also broad courtroom experience and depth in informal settlement situations. These skills translated into efficient, cost effective solutions for my institutions. If it became necessary to brief the board Chair or a board committee, Mark’s approachable communication style facilitated their ability to absorb the legal matters at hand and appreciate the range of probable outcomes of our cases. That same communication proficiency made Mark the perfect choice for executive management and board training situations. Mark has convinced me during recent years that he is hiring for and conveying to his staff these same professional characteristics. If you decide to retain the Whitney Law Group, you will be doing your firm a good service.
Ed LopesCommunity Bank CEO
"Mark and his team at Whitney Law Group were a fantastic resource in a recent non-compete dispute. Over the years, I have witnessed first-hand how much quality legal representation is often tied to how deep your pockets are. Mark and his team offered me that kind of service, taking the time necessary to understand the case and negotiate the best terms for me. From the beginning of my case, it was clear that there were roadblocks that would have been impossible to navigate without Mark's exposure and experience. Leaning on Mark's thoroughness, we were able to act quickly through botched agreements, inept opposing counsel, questionable procedures, and complete disregard for timelines from the opposing party. If you are looking for an attorney in your Labor/Employment issue that will do everything possible to do right given your circumstances, Mark is your guy. Professional, understanding, and laborious."

He was extremely knowledgeable and detailed, and he was very responsive - even on weekends! Mark was an excellent investment.

"I hired Mark to handle my discrimination and non compete case. Before hiring Mark I consulted with three big law firms in the New England area but was not convinced with them and decided to go with Mark. Best decision i ever made. Mark did a spectacular job handling my case and got it sorted out in less than 4 months. He is a great guy to deal with as well. You will never get the feeling you are dealing with a lawyer, you will really feel like you are dealing with a friend. He is always very patient and friendly and will give you the exact facts. He is not out to get your money and is always looking out for your best interests. He is tough and super smart and really knows what he is doing. The best damn lawyer around. Don't waste your time and money with the big firms. I would highly recommend Mark he is a rock star."

"Hired Atty. Mark Whitney twice. Two times a victor! It's rare to find an attorney/firm that actually cares about the outcome, vs. just trying to settle the litigation. Mark was referred to me by my corporate counsel as the best employment lawyer around. They were right. From the initial encounter to hours and hours of preparation time, to the sit-down with the other side's law firm, he was tenacious in his pursuit of the best possible end result. And, he out-argued the facts that their side was too lazy to discover, which cost them in the end, quite a bit of money in the settlement. My company(s) and I owe him a lot as a result."
Bob G.CFO, Publicly Traded Company
"Mark Whitney is hands down the best non-compete attorney that I have experienced. I was a Vice President at a manufacturing company and I had an "iron clad" non-compete contract. I was trying to leave my employer to start my own business. I consulted with several attorneys and all of them were in agreement that I had no chance of getting out of this non-compete contract. I was referred to Mark Whitney from an investment banker that wanted to fund my startup business. After my consultation with Mark ... I knew I found the right lawyer to represent me. I quit my job and I hired Mark. He performed a miracle! I had a full release from my former employer in less than four weeks! I absolutely recommend Mark Whitney."
ScottVP of Manufacturing Company
"EXCELLENT ADVICE DURING JOB ELIMINATION -- I reached out to Mark at the suggestion of a family member when I was worried that my employment of almost 19 years was possibly going to end due to a restructuring. I was able to make good decisions with his advice before, during and after my the eventual loss of my job. He assisted in consultation, review, and feedback on all of my interactions with my former employer critically during the severance package review. I would strongly suggest working with Mark as he was a true professional providing me the information and confidence I needed. I will surely recommend him to any other friends or family members from the Greater Boston, North Shore and Merrimack Valley if they should need legal services. He made me feel brave, empowered and supported during a really difficult time in my professional life."
