John Kaitz| Advanced Masters Women

John Kaitz has been a coach for 30 years. His philosophy is simple: mindful preparation with a disciplined work ethic is the key to success. His coaching philosophy has proven successful in the world of rowing, with over 30 National Championships, and a World Championship, in multiple events with Masters Rowing alone at Marin Rowing Association.

John started his coaching career at the University of California, Santa Barbara. In his first season there, he took a group of young athletes who had never rowed before and turned them into Pac-10 champions. Two of his rowers went on to finish that first season as National Champions in the I.R.A. Open 4- a varsity event- which he coached. His second year there, his team won the Pac-10 title again, in the lightweight event.

John’s collegiate coaching experience also includes UCLA and Stanford, but he has always had a fondness for Marin Rowing Association. In 2014, he returned to Marin to coach elite rower Matt Brown. John prepared Matt for the Olympic Trials, and Matt turned that preparation into an unfathomable feat, crossing the Atlantic with three other rowers in world record time.

John is also an elite trainer. His clients include Jonny Moseley, Michelle Roark, and Michelle O’Keefe. He trained Jonny for the 2002 Olympics, and Michelle Roark for the 2006 and 2010 Olympics. Other clients include Gregory Peck (yes, that one), Cecilia Peck (actor, director), Stephan Jenkins (Third Eye Blind).

John got his Masters Degree from University of San Francisco in Sports and Fitness Management in 1997. John rowed, and played football, at the University of California, Berkeley, while getting his BA degree in Sports Management/Kinesiology in 1988. John is a father to Mariah and Chaz, his best accomplishments to date, other than getting Milda, his wife, to marry him.


Jon Allbin | Advanced Masters Men

Jon joined the MRA coaching staff in 2017 and coaches the Masters men. Jon is privileged to have rowed for John Pescatore at Saint Ignatius and Craig Amerkhanian and Steve Gladstone at Cal. From 2000-06, Jon served as the Freshmen/Novice coach at Stanford University for Coach Amerkhanian. Jon noted the following about MRA: “On the West Coast, there is really nothing like the culture established years ago. I call it a privilege and honor to work here as we challenge assumptions for what is possible in rowers in their 30’s through 70’s.”  Whether someone is relatively new to rowing or returning from a hiatus, he welcomes the opportunity to collaborate with new additions to the squad.


Marc Batchelder | Master B

Marc Batchelder joined the coaching staff in 1996 and has coached both our high school novice men and our adult programs to great success.

Felix Meier | Novice Masters Coach, Adult Sculling & M2R’s

Felix began rowing as a high school freshman at Berkeley High School, looking for a multi-season sport that combined his love of boats and team sports. His competitive rowing career lasted through high school and through two years at UC Berkeley. By the time he graduated from UC Berkeley in 2015, he spent three years coaching rowing and many more teaching in other on the San Francisco Bay. If it’s too windy to row, you might see him windsurfing off of San Quentin!

Besides his previous boating experience, Felix credits his years in physical therapy at the end of his rowing career (as a patient, then an intern) in shaping his coaching philosophy. Since joining Marin Rowing, Felix has worked with adult rowers of every level, but mostly those new to rowing or new to rowing small boats.
