While walking around the property with their dogs, Bruce and Max, Theodore surprised Mariana by getting down on one knee and proposing.

She accepted, and the couple began planning their wedding.

Wesley Reid Theodore was born on September 7, 2024, becoming the first child of Shea and Mariana Theodore.

Following Wesley’s birth, Theodore began balancing the responsibilities of fatherhood with his NHL career.

His son arrived shortly before the beginning of the 2024–25 hockey season, making it an especially eventful period for the family.

In October 2024, Theodore also signed a seven-year contract extension with the Vegas Golden Knights.

The agreement provided long-term professional stability as the couple adjusted to life with their newborn son.

Wesley Theodore’s First Christmas

In December 2024, Theodore discussed celebrating Christmas with his son for the first time.

During an interview with the Las Vegas Review-Journal, he explained that Wesley was still too young to understand the holiday celebrations.

Nevertheless, becoming a father had made the occasion particularly special.

He and Mariana looked forward to establishing new family traditions and spending time together during the holiday season.

Theodore also acknowledged that raising a young child had changed his daily routine and responsibilities away from hockey.

How Fatherhood Influenced Shea Theodore’s Career

Becoming a father brought an important change to Theodore’s personal life.

During the 2024–25 NHL season, he produced some of the strongest performances of his professional career.

Vegas coach Bruce Cassidy suggested that the happiness associated with becoming a father might have contributed to Theodore’s positive mentality.

In February 2025, the Las Vegas Sun reported that Theodore’s improved confidence and consistent performances had helped establish him as one of the Golden Knights’ leading defensemen.

Although his success reflected years of professional development, his growing family provided additional happiness and motivation outside the rink.

Shea and Mariana Theodore’s Second Child

In December 2025, Shea and Mariana announced that they were expecting their second child.

The couple shared the news through social media, revealing that the baby was expected in June 2026.

The announcement included their son Wesley and celebrated the family’s upcoming expansion.

During the 2026 Stanley Cup Final against the Carolina Hurricanes, Theodore discussed the challenges of preparing for another baby while competing for a championship.

According to NHL.com, Mariana was among several Golden Knights players’ wives expecting children during June.

Theodore explained that he and his wife did not know the baby’s sex because they wanted it to remain a surprise.

He also acknowledged that the timing could become complicated if Mariana went into labor while he was playing or traveling with the team.

Despite the uncertainty, he praised her for caring for Wesley and managing the responsibilities of pregnancy during the playoffs.

The Associated Press also reported that the second baby was expected shortly after the Stanley Cup Final.

A subsequent birth announcement identifying the baby’s name and exact arrival date has not been reliably confirmed in the sources reviewed.

Both parents worked outside professional hockey but supported their son’s athletic ambitions throughout childhood.

Theodore discussed their occupations and influence in an interview published by Yahoo Sports in 2015.

His job involved maintaining and repairing industrial machinery, often requiring long working hours.

In a 2013 interview with McKeen’s Hockey, Shea identified his father as the person who had made the greatest contribution to his hockey career.

He praised Cam’s work ethic and explained that he wanted to make his father proud through his own efforts.

Cam Theodore’s Influence on Shea’s Work Ethic

One memorable childhood experience involved Shea accompanying his father to work at the sawmill.

During a school-organized workplace visit, Shea experienced the demanding schedule associated with Cam’s occupation.

The workday began extremely early, and Shea eventually became so tired that he fell asleep in the lunchroom.

The experience helped him appreciate the physical demands of his father’s job.

It also strengthened his motivation to pursue professional hockey.

As Shea advanced through the Seattle Thunderbirds organization, Cam remained an important supporter.

His encouragement helped Theodore navigate the challenges of junior hockey, NHL development and the early stages of his professional career.

Cam Theodore and His Son’s Cancer Awareness Work

Cam Theodore has also supported his son’s charitable efforts in Las Vegas.

In July 2021, Cam and Corrine attended an event announcing additional funding for Kay’s Power Play, a charitable initiative established by Shea in memory of his grandmother.

Photographs published by the Las Vegas Review-Journal showed the parents standing alongside their son during the announcement.

The program provides support for breast cancer screening and assistance to patients in Nevada.

The family’s involvement reflects how personal experiences influenced Theodore’s commitment to helping others.

Corrine Theodore – Shea Theodore’s Mother

Shea Theodore’s mother is Corrine Theodore, who worked for the Royal Bank of Canada while raising her family in British Columbia.

She supported Shea’s hockey development alongside her husband Cam.

Although Corrine has generally maintained a private personal life, she has appeared at public events connected to her son’s career and charitable activities.

Her support became especially important as Theodore began spending extended periods away from home while playing junior hockey in Seattle.

Corrine and Cam encouraged him to remain committed to his goals while adapting to the demands of competitive sports.

In July 2021, she accompanied Shea to the announcement of expanded funding for Kay’s Power Play.

Alyssa Theodore’s Trip With the Anaheim Ducks

One particularly memorable experience involving the siblings occurred in January 2017.

At the time, Shea was playing for the Anaheim Ducks, who organized their first official siblings road trip.

The event allowed players to invite brothers or sisters to accompany the team during games against the Colorado Avalanche and Arizona Coyotes.

Alyssa joined Shea for the trip, becoming one of the invited family members.

According to Sports Illustrated, the opportunity arose shortly after Shea was recalled from the American Hockey League.

The trip allowed Alyssa to experience the daily routine of an NHL player, including team travel and professional games.

Theodore appreciated having his sister nearby during an important stage of his career.

The Anaheim Ducks officially identified Alyssa among the siblings participating in the January 2017 event.

Shea Theodore’s Grandmother: Who Was Kay Darlington?

Another important member of Shea Theodore’s family was his grandmother, Kay Darlington.

Kay was a breast cancer survivor who later experienced another battle with the disease.

She received treatment in Las Vegas with assistance from medical specialists connected to Comprehensive Cancer Centers of Nevada.

In November 2019, Kay participated in a ceremonial puck drop before a Golden Knights game against the San Jose Sharks during Hockey Fights Cancer night.

The moment was especially meaningful because Shea had also experienced cancer earlier that year.

Kay died in June 2020 following her battle with breast cancer.

Her death had a significant emotional impact on Theodore and his family.

Kay’s Power Play: Shea Theodore’s Tribute to His Grandmother

In November 2020, Theodore established Kay’s Power Play, a charitable initiative named in honor of his grandmother.

The program was developed in partnership with Comprehensive Cancer Centers and Susan G. Komen Nevada.

Its purpose is to improve access to breast cancer screenings and provide assistance to people facing financial challenges during treatment.

In October 2026, KTNV reported that the initiative had raised more than $450,000 in total contributions.

The program continued supporting mammograms, patient care and other assistance for people affected by breast cancer.

Theodore explained that honoring his grandmother’s memory remained one of the main motivations behind the initiative.

His parents have also participated in events supporting the program.

Shea Theodore’s Cancer Diagnosis and His Family’s Support

In 2019, Shea Theodore experienced one of the most difficult periods of his personal life when he was diagnosed with testicular cancer.

The diagnosis occurred after he represented Canada at the IIHF World Championship in Slovakia.

An unexpected laboratory result led doctors to investigate further, ultimately identifying the disease.

Theodore underwent surgery and subsequently returned to professional hockey.

In a personal article published by The Players’ Tribune in September 2019, he explained that telling his girlfriend and parents about the diagnosis had been particularly emotional.

He also acknowledged that cancer had affected other members of his family, including his grandmother Kay.

The experience strengthened his appreciation for early detection, medical treatment and family support.

After recovering, Theodore continued playing for Vegas and eventually helped the team win the Stanley Cup in 2023.

How Shea Theodore’s Family Influenced His Hockey Career

Shea Theodore’s journey to professional hockey began in Aldergrove, British Columbia.

His performances attracted attention from Western Hockey League scouts, and the Seattle Thunderbirds selected him in the 2010 WHL Bantam Draft.

He developed into an outstanding offensive defenseman while playing for Seattle.

During the 2014–15 season, he won the Bill Hunter Memorial Trophy as the Western Hockey League’s top defenseman.

His father Cam remained an important influence throughout this period, encouraging him to work hard and maintain discipline.

Theodore was selected by the Anaheim Ducks in the first round with the 26th overall pick in the 2013 NHL Entry Draft.

He made his NHL debut in December 2015 and continued developing within the Anaheim organization.

In June 2017, the Ducks traded him to the Vegas Golden Knights as part of an arrangement connected to the NHL Expansion Draft.

The move became a defining moment in his career.

Theodore helped Vegas reach the Stanley Cup Final during its inaugural season and later contributed to the franchise’s first championship in 2023.

Throughout these achievements, his wife, parents and sister remained important sources of encouragement.

Shea Theodore’s Family Life in Las Vegas

In December 2025, they announced their second pregnancy.

During the 2026 Stanley Cup Final, Theodore expressed appreciation for Mariana’s support while she cared for Wesley and prepared for another baby.
