Lisa Gastineau Net Worth

What is Lisa Gastineau's net worth?

Lisa Gastineau is an American television personality, entrepreneur, jewelry designer, former model, and New York socialite who has a net worth of $1 million. Lisa Gastineau is best known for co-starring with her daughter, Brittny Gastineau, on the E! reality series "The Gastineau Girls," which aired from 2005 to 2006 and followed the glamorous mother-daughter duo through New York society, dating, fashion, and family life.

Although many viewers know her from reality television, Lisa's career extends well beyond "The Gastineau Girls." She has worked as a model, entertainment correspondent, boutique owner, luxury retail buyer, jewelry designer, and on-air shopping television personality. She also became widely known through her marriage to former New York Jets defensive end Mark Gastineau, one of the NFL's most flamboyant stars of the 1980s. After a highly publicized separation and divorce, Lisa rebuilt her identity as an independent businesswoman and single mother, eventually turning her fashion background and close bond with Brittny into a television and lifestyle brand.

Early Life

Lisa Gastineau was born Lisa D'Amico on December 11, 1959, in Rockland County, New York. She grew up in New City and is a third-generation New York native. She was discovered as a model during her teenage years, giving her an early introduction to the fashion and entertainment industries.

Lisa later attended the University of Alabama, where she studied broadcasting and communications and was involved with the university's athletic culture as a cheerleader. Although she left college before completing her degree, her time studying media and public speaking helped lay the foundation for her later work in television.

Marriage to Mark Gastineau

When Lisa was 19, she met Mark Gastineau, a rising defensive end for the New York Jets. Mark would become one of the most famous defensive players of the 1980s as part of the Jets' "New York Sack Exchange," known for both his pass-rushing ability and flamboyant personality.

Lisa and Mark married in 1979 and welcomed their daughter, Brittny Gastineau, in November 1982. Their marriage placed Lisa in the center of New York sports celebrity and tabloid attention. The couple separated in 1986 after Lisa learned of Mark's relationship with actress Brigitte Nielsen. Mark and Nielsen were later engaged but never married, and they had a son together named Marcus.

Lisa and Mark finalized their divorce in 1991. Their split was financially and publicly difficult. The divorce reportedly consumed much of Mark's NFL fortune, and in later years Lisa was reported to have pursued claims related to unpaid spousal support, child support, and Brittny's college expenses. Mark's financial struggles became public again in 2019, when health problems and money issues led him to launch a GoFundMe campaign that raised about $47,000.

Fashion and Retail Career

After her divorce, Lisa reestablished herself in New York's fashion and social scenes. She had more than a decade of hands-on experience in luxury retail, buying, and boutique ownership. In the 1980s, she opened Lisa Pieces, a high-end boutique on Long Island's Gold Coast. She later opened Avalon in the Hamptons, further developing her reputation for upscale fashion and accessories.

In the late 1990s, Lisa collaborated with her own mother on Trends, a boutique focused on vintage jewelry and textiles. That business reflected one of Lisa's strongest professional instincts: identifying glamorous, collectible, and personal pieces that could appeal to stylish women looking for something beyond mass-market fashion.

Television Career

Lisa used her broadcast communications background to move into television, working as an entertainment correspondent for Fox's "Good Day New York." In that role, she covered celebrity, lifestyle, and entertainment stories, building experience as an on-camera personality before reality television made her a household name to E! viewers.

Her biggest television breakthrough came in 2005, when she co-starred with Brittny in "The Gastineau Girls." The series followed their lives in New York high society and focused heavily on their unusually close mother-daughter relationship. The show ran for two seasons and became part of the early wave of glamour-driven reality television that helped pave the way for later celebrity-family and lifestyle franchises.

Lisa has also appeared on programs including "The View," "Keeping Up with the Kardashians," "Entertainment Tonight," "EXTRA," "Oprah," and "Married to Rock." Her television persona combined New York confidence, humor, glamour, and a willingness to be candid about dating, beauty, family, and reinvention.

Jewelry and Business Ventures

Lisa's most important business partnership has been with Brittny. Together, they created Tres Glam, a fine jewelry collection that combined New York sophistication, Hollywood flash, and bohemian-inspired diamond designs. Lisa served as president and designer of the brand, building on her decades of experience in buying, styling, and luxury retail.

The mother-daughter team later expanded with "Gastineau Glamour," an estate-inspired jewelry line for HSN. Lisa appeared on-air as both designer and presenter, using her television experience to sell directly to consumers while presenting the collection's vintage-inspired look and accessible glamour.

Health and Personal Life

Lisa has faced health challenges, including treatment for lung cancer in 2009. She has also been candid over the years about beauty, cosmetic procedures, and the pressures of maintaining a public image in the fashion and entertainment worlds.

Her closest public relationship has always been with her daughter, Brittny. Their bond defined "The Gastineau Girls" and later extended into business through jewelry, fashion, and lifestyle ventures. While Lisa first became famous to many as Mark Gastineau's wife, she ultimately built her own identity as a broadcaster, entrepreneur, designer, and reality television personality. Her career reflects both the glamour of New York society and the resilience required to reinvent oneself after a very public divorce.
