Sontag Advisory, among the largest independent advisory firms on the East Coast, has expanded to Westport, Conn.
   The new office will be headed by Michael N. Delgass, a managing director of the firm, which has more than $3 billion under management.
   Delgass has prior experience working with clients in Connecticut, having joined Sontag from the Greenwich, Conn., office of the law firm Day Berry & Howard, where he served as an estate planning attorney, according to Sontag. Delgass has more than 10 years of financial planning experience, with a specialty in tax, succession and estate planning, according to the firm.
   "As we've continued to grow, our clients have demanded the kind of accessibility that necessitates a greater presence in Connecticut," said Howard Sontag, president and founder of Sontag Advisory. "Michael, having spent the last six years advising in the Connecticut market, has the kind of expertise that will help us to better serve our clients as well as to grow in an important region."
