Michael Sontag serves as the chair of the firm’s Trusts & Estates Practice Group. Michael’s extensive experience in this area has solidified his national reputation as a leader in generational-asset protection, as well as strategic and financial planning for individuals, families and businesses.
For nearly 40 years, Michael has worked closely with individuals, fiduciaries, wealth advisors, businesses, trustees and beneficiaries to provide strategic, financial guidance while serving the confidential and sophisticated estate-planning, estate-administration and business needs of an extensive client list of celebrities, athletes, politicians, musicians, business owners, executives and high-net worth families and individuals. These wide-ranging experiences have allowed Michael to evolve a unique and often tailored service-offering specific to each client’s nuanced and complex individual needs.
Michael is often sought by a unique variety and caliber of clients due to his empathetic and honest relationship skills and the countless recommendations from former clients that attest to his ability to transform client vulnerability about the future into confidence. Michael’s steadfast dedication to his craft has successfully helped protect years of client financial achievement, ensuring fair tax treatment and helping individuals and businesses appropriately avoid the imposition of hundreds of millions of dollars in taxes.
