Board of Directors

Cathy Tarr, Founder & Executive Director

In 2016 Cathy fell in love with hiking while exploring The Whites in Shelburne NH and trail angel-ing for AT hikers. Her love for the PCT and long distance trails inspired her to volunteer in the effort to find Kris Fowler in August 2017. While searching for Kris, she saw a flyer for another missing hiker, David O’Sullivan in California. Cathy has brought together an amazing team of people eager to help families of missing hikers. Cathy has coordinated numerous volunteer search efforts, offering her time and experience to families who are searching for a loved one. As a compassionate and dedicated family liaison/advocate, she provides wise counsel to families, connecting them with vetted search resources. Cathy is the family advocate on the David O’Sullivan case.

Mackenzie Pollard, Board Secretary

From the Central Cascades in Washington State, MacKenzie found her love of the outdoors from her parents. While section hiking the PCT she found strength in the ‘Tramily’ who support each other along the way. In October of 2016, she heard about Kris Fowler, a missing PCT hiker. He was from Ohio, so his family wasn’t readily available to search for him long-term so she volunteered to help and MacKenzie’s desire to support families in their endeavor to find closure for their loved ones was solidified. In her new home in Hawaii, she holds true to her PCT trail name ‘Strawberry’ with her incessant need for sunscreen and shade.  

Jill Tavolazzi, Board Treasurer

Jill retired as an Administrative Analyst from San Diego State University where she earned a B.A. in Public Administration and Urban Studies. During her time there she was inducted into the Phi Kappa Phi Honor Society in recognition of her outstanding service to the University. Eventually, she served as the Treasurer for SDSU’s chapter and held that position for over 10 years. While serving as Treasurer, the chapter earned outstanding recognition as Chapter of Excellence for several years. After she retired, Jill was on a visit to Ireland in the summer of 2017 when David O’Sullivan’s family realized he had gone missing while hiking the PCT. Jill was friends with David’s mother and aunt, so hearing the devastating news first-hand truly impacted her. After returning home to the San Diego area Jill participated in her first group search for David with Irish Outreach, spearheaded by Cathy Tarr. Jill felt an instant connection when meeting Cathy, especially after discovering they were both born in Western Pennsylvania. Since then Jill has participated in several searches for David. After meeting so many amazing volunteers, and with David’s family so far away, Jill is committed to doing whatever she can to find David and other missing hikers.

Stewart Krull, Board Member

As an award-winning executive creative director, Stewart brings more than three decades of advertising and marketing experience to the Fowler-O’Sullivan Foundation. But it’s his experience as a grieving father that makes Stewart’s passion for the FOF and its mission so profound. When 20-year-old Zachary Krull failed to return from a solo hike during a sudden and severe winter storm at Olympic National Park in April 2017, Stewart and his family learned firsthand what local law enforcement and volunteer SAR teams can and cannot do when time, weather and logistics conspire against you. Sparing the family of facing long-term ambiguous loss, Zachary’s remains were accidentally discovered, and recovered, three months later. For Stewart, there can be no better way to honor the memory of his nature-loving son than working to help the Foundation prevent or bring closure to other missing hiker cases.

Sally Fowler, Board Member

Sally Fowler’s life changed forever in the fall of 2016, when her stepson disappeared while hiking the Pacific Crest Trail. Kris “Sherpa” Fowler started his PCT thru-hike at the California/Mexican Border on May 8—Mother’s Day. Kris was near the end of his 2650-mile PCT journey to the Canadian Border when he was last seen on Oct 12, 2016, at the White Pass Trailhead in Washington state. There have been many official and volunteer searches for Kris, including a search that was, at the time, the largest in Washington state history. Unfortunately, no definitive signs of Kris or his whereabouts have been found. In 2016, Sally and her family created the Facebook group Bring Kris Fowler/Sherpa Home which now has over 8K followers. This group provides guidance to other families when a loved one goes missing in the wilderness. In 2017, Sally and another member of this FB group helped reunite a family with a loved one who had been missing for 4 years.
During the early stages of Kris’s disappearance, families of the missing offered Sally useful advice. She has paid this forward by providing support to several families of missing hikers and advising them on what steps to take. “It is an honor that the Fowler-O’Sullivan Foundation was named after my son, Kris,” Sally says. “I want to continue helping others who are experiencing what is probably the most devastating event in their life.”

The two women combined forces to organize volunteer searches for both John and David, a PCT hiker who vanished the year before. During one search in late May, Cathy spotted a bloody sock about 100 feet in front of the truck in the direction of mile marker 193 on the PCT. After this discovery, the authorities conducted another search and John’s body was found.

Jessica Knoelk Bio

Jessica is an avid outdoor adventurer from Idaho, who loves to teach others outdoor recreational skills, while sharing her knowledge on preventative SAR and backcountry safety. From an early age, she developed a love for the mountains and everything outdoors. Growing up in southeastern Idaho, provided her many opportunities over the years to travel and explore the vast wilderness areas all throughout Idaho, Montana, Wyoming, and Oregon. Jessica loves to hike and backpack year round with her dogs, son, and friends. She also enjoys winter camping, snowshoeing, hammock camping, learning primitive skills, hiking, backpacking, kayaking, hunting, fishing, photography, discovering historical hidden treasures in the backcountry and more. Jessica continues to build upon her knowledge and skills, and she hopes to become a certified Drone piolet in the future.

In 2010, Jessica suffered sever injuries from a four-wheeler accident that left her paralyzed from her hip to her toes on her left side. After a few surgeries and nearly 3 years of physical therapy, she slowly regained her ability to walk again. That experience alone was one of the hardest times of her life as she battled a deep depression from not knowing if she would ever walk again. With every pain staking step forward, that depression eventually turned to hope as she achieved about 80% recovery. Despite the permanent nerve and muscle damage that remains today, she chose to put her fear behind her and challenged herself to keep moving forward.

With a newfound hope and positive outlook, she joined her local SAR unit and became a K9 handler and grant writer. After retiring her best friend and K9 partner, she became a certified Man Tracking trainer through Joel Harden Professional Tracking Service. She has been with JHPTS for more then 8 years, a K9 handler for 6 years, and a volunteer SAR member for more than 10 years. Jessica studied Recreation Management and obtained her bachelor’s degree at Brigham Young University-Idaho.

In fall of 2020, Jessica became involved with the search for a missing out of state hiker that disappeared in the rugged mountains of Idaho. Through the combined efforts of her and a few other kindred spirits in the area, they have been assisting the family by continuing to search long after the initial search was called off for the missing hiker. While researching cases on other missing hikers, Jessica discovered an article about another missing hiker that mentioned the Fowler-O’Sullivan Foundation. Jessica became intrigued with the foundations mission to aid in the search for missing hikers and she wanted to know more. After reaching out to the foundation for help, she found hope in learning there are other compassionate individuals out there who are just as dedicated to helping bring peace to families in need. (*Ongoing efforts to locate the missing hiker in Idaho will continue until she is found.*) With Jessica’s dedication, knowledge, skills, and years of experience, she is the newest member of our team.
