From Supporter to Survivor: Why Mark Monson Makes Waves

When Mark Monson first participated in Swim Across America – Dallas in 2016, he joined because he loved to swim and wanted to support a cause that had impacted family and friends affected by cancer.

What began as a way to give back became deeply personal in January 2022 when Mark was diagnosed with Stage IV colon cancer.

“Before my diagnosis, I supported Swim Across America because of the people in my life who had fought cancer,” said Mark. “After my diagnosis, the swim became much more personal.”

Now 49 and living in Frisco, Texas, Mark is celebrating a milestone that once seemed uncertain: he currently has no evidence of disease.

Over the past 10 years, Mark has raised approximately $15,000 for Swim Across America – Dallas. This year, he will once again take part in the annual open water swim on Saturday, September 19 at Lake Rockwall, benefiting Baylor Scott & White Charles A. Sammons Cancer Center.

His experience as both a participant and survivor fuels his commitment to the cause.

“I am motivated to continue raising money because I know precisely where the money goes, and I can see progress being made,” Mark said. 

Proceeds from the SAA-Dallas community event are granted to the Texas Cancer Interception Institute (TCII) within Baylor Scott & White. The TCII brings together advanced technology, research and care teams to help detect cancer at its earliest stages — when it is most treatable.

“Fifteen years ago, my diagnosis was a death sentence. At the time I’m writing this, I have no evidence of disease. I want that for everyone who is diagnosed with cancer.”

For Mark, Swim Across America is about more than fundraising. The annual event motivates him to stay active and provides an opportunity to connect with a community united by a common purpose.

“Swim Across America motivates me to keep pushing to be able to swim each year,” he said. “I also enjoy seeing friends there, both old and new.”

As Mark prepares for another Swim Across America – Dallas event, he hopes his story serves as a reminder that every dollar raised helps move cancer research forward and brings hope to patients and families facing a cancer diagnosis.

A letter from Rob Butcher, the CEO of Swim Across America:

Dear Swim Across America Community,

We began with a simple yet bold belief, that a community united in purpose can turn hope into action by innovating new cancer treatments and improving quality of life. Because of you, that belief is becoming a reality.

Coast-to-coast and all year long, survivors, advocates, and partners raised critical funds that directly support innovative research, advance detection, and improved patient programs. Every dollar granted is action towards breakthroughs and support for families navigating the unimaginable. We are unique that the funds raised in each community stay local, strengthening relationships with academic and community partners, and ensuring donors know the impact of their generosity.

We celebrate progress because families continue to hear the words, “You have cancer” and deserve to hear, “There is Hope.” We are committed to sharing our impact and inspiring generations to Make Waves to Fight Cancer with Swim Across America.

With gratitude,

Rob Butcher
