Mark Edmondson Obituary

Published by Legacy Remembers from Jun. 20 to Jun. 21, 2025.

Mark Edmondson, a widely admired sales leader, resilience coach, and founder of Positive Vibes Only (PVO Life), died peacefully on June 14, 2025, at the age of 43. His wife, Rebekah ("Becci"), and their son Finn held his hands as he passed-surrounded by love, peace, and the deep admiration of those whose lives he touched.

Diagnosed with stage 4 cancer in 2017, Mark was told he had less than a year to live. He responded not just by fighting for more time-but by devoting that time to helping others change their perspective on life. Over the next eight years, while enduring more than 140 rounds of chemotherapy and over 30 operations, Mark became a beacon for openness, courage, and purposeful living.

Professionally, Mark served as Head of Sales for UK & Ireland at Legacy between 2015 and 2020, where he brought both sharp strategic vision and contagious energy. As a colleague remembered: "We worked hard and had many laughs. He built not just a business, but a culture." Yet after his diagnosis, he reimagined success altogether. "Within hours of the diagnosis, that disappeared," he later said. "I don't care for work any more, but I believe strongly in having a sense of purpose."

That new purpose took shape as Positive Vibes Only, a mindset and coaching initiative designed to help people face adversity. In his own words, from his LinkedIn profile: "Nothing prepares you for being told you have less than a year left to live… Whilst I still live with cancer, my perspective on life has completely changed. I live with greater joy and appreciate what my life still offers me… I've had hard conversations with people and challenged myself to face up to the previous status quo and change it, allowing people to see who I really am."

Mark believed deeply in mental health support, vulnerability, and changing the culture around how we talk about hardship: "Society still encourages us to be brave, to stand up to our challenges and internalise them. My aim is to remove that notion… Everyone I know has endured something that has impacted how they view life… This service isn't just for major trauma-it's for everyone. So, let's talk."

Those values weren't just slogans-they were how he lived. As his wife Becci movingly shared: "Even as his time and energy became more limited, he continued to give-generously and without fanfare. He showed up for others with strength, support, and kindness."

Mark was also a devoted father to Wilf and Finn, and it was for them that he fought hardest. His battle gave them eight extra years of laughter, learning, and connection. "That fight gave them time to really know the man he was-and how to carry that forward," Becci wrote.

To friends, he was "Sven," a nickname that matched his big presence and even bigger heart. His motto-"WE GO AGAIN"-echoed not just resilience, but defiance in the face of despair. Whether coaching, mentoring, or speaking publicly, he always returned to one essential idea: "It's not what happens to us, but how we react that defines who we are."

Mark Edmondson was defined by how he reacted: with grace, humor, strength, and relentless compassion.

He is survived by his wife Becci, his sons Wilf and Finn, and by a wide network of family, friends, and mentees whose lives he changed through action and example.

Donations in his memory can be made to Martlets Hospice in Brighton, whose care helped Mark spend his final days in peace and dignity.

He gave everything. He showed us how to live.

His energy lives on-in every conversation he started, every perspective he changed, and in every person lucky enough to have known him.

This photo is of the European team when we had our annual conference in my home town of Moy. By a sad twist of fate, Ewa, (our colleague from Poland ) standing beside Mark and reaching for my head passed away suddenly just three days before Mark. It was a very sad week for the whole team

Becci, I am devastated to read this, I know it had become inevitable, nevertheless, it is profoundly sad. It was a joy to meet and work with Mark we worked hard and had many laughs too. Many in Legacy remember him fondly and have always asked about his welfare. As you say it was such an inspiration to see the effort he made to squeeze every last minute out of his life and to make a difference. For Finn and Wilf they will have the memories of those years and they will always a role model for their life. And to you, being by his side throughout fighting the battles with him, being his strength to help him through those darkest times is remarkable and your boys should be equally proud of you. God Bless.

I was fortunate to have met Mark while working for Legacy. Through the years, I have admired his positive outlook in the face of a devastating diagnosis and his sheer determination to defy the odds given him. He's touched many lives and influenced my own approach to life, but I will forever find it profoundly unfair he did not get a lifetime with his family.

To his family, may your happy memories of Mark be a comfort to you in this difficult time.

With heartfelt sympathy,
