‘Gary Svirsky and Tanc Schiavoni represent an experienced coverage team with trial and presentation experience. Both are great on their feet in court, as well as good strategists.’ 

‘OMM recruits the best legal talent, and many other firms that do insurance do not attract the same quality of talent. Thus, you are getting very smart and talented people at all levels. Unlike many other white-shoe firms that do not do insurance, OMM is committed to the industry and has a very high level of experience and expertise.’

‘Tanc Schiavoni is extremely experienced and works on both bankruptcies and insurance, which is very helpful to insurance companies when their policyholder is in bankruptcy (e.g. Boy Scouts). He is a great trial lawyer as well as written advocate. Allen Burton is someone who has spent the past two decades working on insurance matters, including reinsurance. He is great at preparing witnesses to testify, written and oral advocacy.’

‘I found partner Gary Svirsky and associate Janine Panchok-Berry to not only be extremely intelligent and talented but to genuinely care about their clients.’
