    Divorce is so difficult and having to walk through this alone would have been unthinkable. Catia Tavares was there every step of the way. Nothing phased Catia nor the rest of the team at Sinels. Dealing with the divorce itself and handling expertly the complexities of the ancillary matters due to the various business’ and Family Trusts involved has made my journey as smooth as possible. In addition Catia has been available at all times to sort out the expected as well as the unexpected elements of my particular case.
