His loved ones gathered by his beside on November 30th to say their final farewells, but told his caretakers they wished Jessen's heartbroken pup, Mollie, had the same opportunity.
That's when hospital staff stepped in to help, according to Jessen's sister Michelle.
"The hospital did the sweetest thing for us and allowed us to bring my brother's dog in to 'say goodbye' so she'd know why her human never came home," Michelle Jessen wrote on Facebook. "If you knew my brother, he really loved his sweet dog."
The touching moment was captured on video and now has 11 million views on Facebook.
"We are sincerely touched and humbled by others' stories, their sharing in our sadness and the kindness of so many people," Michelle Jessen said.
Ryan Jessen's family decided to donate his organs, saving the life of a 17-year-old California teen on December 1st.
"As sad as it is to lose Ryan, we know his heart is going to bring so much joy to the family of the recipient," Michelle Jessen said in a Facebook post.
As for Mollie, though she's still grieving for her dad, Michelle Jessen assured everyone that she will always remain a valued part of the family.
