In developing “Best Law Firms,” U.S. News – Best Lawyers® utilizes a rigorous selection process to ensure a vetted, high-quality legal guide. The intent is to showcase the most renowned law firms across the country. The publication surveys lawyers and clients about a firm’s level of expertise, business acumen, client accessibility, and responsiveness, among other areas.

U.S. News – Best Lawyers® requires firms to have at least one attorney recognized in that year’s edition of The Best Lawyers in America©. With only a small margin of private practice attorneys selected to The Best Lawyers in America© — just 6% — the candidate pool includes a select few firms.

The published edition of U.S. News – Best Lawyers® “Best Law Firms” only lists the firms that scored the highest during the selection process, placing them along three tiers for each legal area and region. Tier 1 sits at the very top.

Locally & Nationally Recognized


At Wisner Baum, we are very proud to have earned rankings in “Best Law Firms”, particularly because such rankings cannot be achieved without a high level of respect from our clients and colleagues.

Here are some of the client reviews the firm has received.

Former Wisner Baum client Kim Witczak wrote:

“I wish more lawyers had the courage like Wisner Baum. They work tirelessly to expose the wrongdoings of the corporations that are harming or killing the public. They are strategic and know the importance of documents that speak truth in black and white. My life would look very different today if it weren't for Wisner Baum.”

Former Wisner Baum client Wendy Dolin shared:

“What makes Wisner Baum the best? Brent Wisner and Michael Baum lead a team of lawyers and staff that are fantastic. They are masterful researchers and are able to uncover hidden information that companies hide and misrepresent. When they believe in your case, they will spend time and resources to discover the facts and hold companies accountable for the harm they have done to consumers. They never give up. They won a very complicated case. It was a rare case where the parent company was held accountable for the generic version of the drug. We won a jury verdict. Unfortunately, it was overturned on preemption and Wisner Baum didn't give up. For years, they battled to keep this verdict. Regardless of the outcome, we won our jury verdict that stunned GSK. On a personal note, Wisner Baum has become family. They always make you feel that your loss is their loss. I have never seen a more compassionate and caring group of lawyers. To this day, I still consider them all family. When you combine the brilliance of their capabilities, masterful trial skills with the compassion and commitment to making a difference in the world with their enormous heart, I cannot imagine a more perfect law firm. They are the best, any other law firm pales by comparison.”

Notable lawyer David Rapoport, Esq. of Rapoport Law Offices wrote:

“I have known the work of this firm for over thirty years and during that time they have consistently delivered top quality work for their clients.”

Another of our distinguished colleagues, Mark Burton, Esq. of Audet & Partners, described us as “One of the top trial firms in the US.”

And last but not least, we were honored by what Dr. Joseph Glenmullen, a board-certified neurologist and instructor at Harvard Medical School, had to say. He wrote:

“Wisner Baum is a phenomenal law firm, at the cutting edge of product liability litigation. I have worked with them as a medical expert for decades. They do a masterful job leaving no stone unturned in discovery, crossing all the Ts and dotting all the Is (sic). The lawyers are so intelligent and so committed to advocating for their clients.”
