*************************************************

Constance was born in Chicago, Illinois. She was raised in Connecticut.

At age five, she appearing on the iconic CBS children's program, The Howdy Doody Show.

Constance majored in English at a small Catholic women's college -- before moving to New York City – 5 days after graduation --  to pursue a career in acting. 

Constance is best known for playing Laura Avery Sumner on the hit primetime drama Knots Landing. She starred on the series from its 1979 debut until 1987, when Laura's heartbreaking death from a brain tumor became the emotional centerpiece of the show's landmark 200th episode.

Constance made her television debut in 1976, playing Altrude, a young woman whom Edith Wilson (portrayed by Elizabeth Hubbard) takes under her wing and comes to love like a daughter, in the NBC television movie First Ladies Diaries: Edith Wilson. The film was directed by Nick Havinga, who would later go on to direct 17 episodes of Knots Landing.

Early in her career, Constance appeared on the acclaimed drama Family as school dance teacher Ms. Massey. The series was written by David Jacobs, who would later create both Dallas and Knots Landing.

Before becoming television characters in the Dallas/Knots Landing universe, Linda Gray and Constance appeared together in the 1979 television movie The Two Worlds of Jennie Logan. Linda would later star as Sue Ellen Ewing on Dallas, while Constance became Laura Avery on its spin-off, Knots Landing.

In 1979, Constance played Lindsay Wagner's best friend in The Two Worlds of Jennie Logan. Nearly a decade later, she reunited with Wagner to once again play her best friend in the 1988 television movie Nightmare at Bittercreek.

Laura Avery was created specifically for Constance McCashin. Series creator David Jacobs wrote the role for her after working with her on his earlier series Married: The First Year.

McCashin played John Ritter’s wife who runs away with their neighbor played by Bert Convy in the 1984 TV movie  Love Thy Neighbor.

To reflect Laura's sweet and approachable personality during the early seasons, creator David Jacobs requested that the wardrobe department dress Constance primarily in soft pastel colors.

She has served on the National Advisory Board of the National Down Syndrome Society.

Constance is the sister-in-law of producer and screenwriter David Weisman.

On Knots Landing, Laura's turbulent marriage to the insecure and emotionally abusive attorney Richard Avery (John Pleshette) was praised for its honest and emotionally complex portrayal of a troubled relationship—something rarely seen on television at the time.

One of Knots Landing's earliest and most controversial storylines came in the 1980 episode "The Lie," in which Laura is sexually assaulted, hides the truth, and draws Val into her deception. The groundbreaking storyline explored trauma, shame, and the emotional aftermath experienced by survivors.

Laura Avery was the mother of three children: Jason aDaniel, whom she had with Richard Avery, and Meg, whose father was Greg Sumner.

During the late 1980s, rising production costs and declining ratings forced Lorimar-Telepictures to cut budgets on its three biggest primetime soaps—Dallas, Knots Landing, and Falcon Crest. As a result, both Constance McCashin and Julie Harris were released from Knots Landing at the start of Season 9.

Producers kept Laura Avery's death a closely guarded secret until the closing moments of the episode "Flight of the Sunbirds," even though Constance did not appear on screen. The shocking reveal set the stage for the emotional two-part 200th episode, which centered entirely on Laura's death and funeral while reflecting on the show's first eight seasons.

Constance has said she was stunned by her departure from Knots Landing. Having recently welcomed a baby and begun building a new home, she believes her exit was simply part of the show's budget-cutting measures.

Both of Constance's real-life pregnancies were incorporated into Knots Landing. Her son, Daniel Weisman, even appeared on the series as Laura's baby Daniel, while her daughter inspired Laura's second child, Meg.

The Season 9 episodes "Noises Everywhere: Part 1" and "Noises Everywhere: Part 2" served as Knots Landing's 200th and 201st episodes. Focusing on Laura's death and funeral, much of the emotional dialogue was developed after the cast spent a weekend improvising scenes together at David Jacobs' ranch.

Actors Constance McCashin, Alec Baldwin, Howard Duff, Madison Mason, and David Hayward all appeared in both Knots Landing and the 1985 television movie Love on the Run. In the film, Constance shared scenes with both Baldwin and Duff.

She had a recurring role on the CBS sitcom Brooklyn Bridge, playing Rosemary Monahan opposite James Naughton as her husband, Lt. Patrick Monahan.

When Knots Landing Reunion: Together Again aired in 2005, Constance declined to participate in the special or allow her clips to be used because in her new career as a psychotherapist she feared it could confuse her patients. As a result, her face had to be blurred in archival footage.

Constance's son, Daniel Weisman, played Laura's infant son on Knots Landing. He later spent 15 years as a successful music manager, working with artists including Capital Cities, Wale, Mike Posner, Tobe Nwigwe, and Big Sean before becoming a partner in Private Wealth Management at AllianceBernstein.

After leaving Hollywood, Constance relocated to Boston and obtained a Masters in Social Work from Simmons College. From there she went on to work in the counseling center at Brandeis University, while simultaneously teaching in their theater department.

She reinvented herself as a licensed social worker and psychotherapist, specializing in the treatment of eating disorders and body image issues.

In April 2009, Constance reunited with her Knots Landing castmates at the TV Land Awards to celebrate the series' 30th anniversary. Joining her were Michele Lee, Donna Mills, Joan Van Ark, Ted Shackelford, Kevin Dobson, Lisa Hartman Black, Don Murray, and Michelle Phillips.

Constance appeared as a celebrity contestant on Dick Clark's The $25,000 Pyramid, later served as a panelist on Super Password, and represented CBS during the 1984 edition of Battle of the Network Stars.

She made her final screen appearance in the 1999 comedy The Out-of-Towners, playing Mrs. Wellstone. The film was directed by her husband, Sam Weisman.

Constance guest-starred in the two-hour series finale of the acclaimed drama In the Heat of the Night, playing wealthy widow Pauline Given Ryan, who marries former police officer John Ryan, portrayed by Bill Cross.

McCashin lives in West Newton, Massachusetts, with her husband, producer and director Sam Weisman.
