    Sergio works closely with his clients during every step of a project, from contract drafting and negotiation prior to commencing work, through negotiating disputes mid-project and, when necessary, litigating to judgement after the job is complete. He understands how frustrating it can be for business owners and home owners, after another party fails to keep legally binding promises and has a superb ability to collect all the necessary data to properly asses each situation and give his clients a pragmatic analysis of all the options available in order to come up with a winning strategy.
