If there is one word to describe Marina, it’s persistence. She has always been highly in-tune with her strengths and weaknesses and uses each to help move her swimming to the next level. Standing at only 5’6” she doesn’t have the height or body composition that many elite female swimmers possess, instead she has tremendous grit which keeps her firmly grounded in her goals. Marina’s coaches have had huge impacts on her career. Bob Bowman writes quotes during his practices, and one always stuck with her: “Excellence isn’t an act, it’s a habit” –Aristotle. 

Marina grew up as a part of the Mission Viejo Nadadores where she swam with the notoriously distance oriented program run by former Olympic Coach, Bill Rose. Although she specializes in sprint races, her best performances happen when she trains 5,500 to 7,500 yards a practice, something that she attributes to her days on the Nadadores.

To the frustration of many of Marina’s past coaches, arm speed and power was never an area of strength.  

“I remember watching the 2008 Olympics and it was really the first time, as a swimmer, that I had a lightbulb moment. Athletes were winning (and losing) races because of underwaters. I knew that this was my ticket into the next level of swimming. I have always had extremely high leg endurance and power so without any coach prompting, I spent every practice focused on underwaters, every kick set became an underwater set, and every wall had to have five or more kicks. Developing a skill takes time and patience and there was a period of time when I was dead last in every practice. Then, one day I was passing people I had never passed before and I was dropping insane amounts of time. I firmly believe that talent will only take an athlete so far, after that putting in the time and consistency to develop habits is the key to success.”

She was known throughout the PAC-12 conference for her underwater speed and endurance, leading her to shine in short course swimming, particularly in butterfly, backstroke and freestyle. She has spent years working to perfect the power and distance in each undulation. She says: “There’s no secret to being a great underwater swimmer besides being comfortable being uncomfortable. Find your flow and go.” 

While it is true that much of athletic success is found in persistence, Marina is a firm believer in mental health. Coming from an intense distance team, she felt her team was at times discouraging and difficult so she surrounded herself with positive people to stay motivated each and every practice and meet.

While Marina was team captain of the ASU team, she found that she was not so much of the outspoken type of leader, but she preferred to lead by example. She encouraged the team to create a community that lifted each other up and celebrated personal victories instead of being in competition with each other.  

As a former ESL teacher, she knows that every student has different learning styles and she carries that attitude over into her coaching. Not every drill or style of swimming is going to fit for each athlete but she encourages each person to try it out and find what works best for them.

Participant Feedback From Marina's Clinics

“They were amazing! Marina and Glenn were great speakers and terrific at communicating the drills and the important focus points. They kept all of the 11 and unders engaged for the entire time. We will be cheering for Marina as she heads into 2020!” -Kirsten, from Oklahoma City, OK 

“Chloe, Marina, and Glenn were fabulous! I was typing so quickly in my ‘notes’ on my phone and videoing everything I could! I loved everything and soaked it all in! The entire clinic was well done and extremely helpful and beneficial. My athletes talked about the clinic every day afterwards and all the way home” -Cyndi, from Lubbock, TX 

“Marina’s story resonated with my daughter. Not everyone is going to have a medal, but you still give it your all. You are doing it for your “why”. And as my daughter said, ‘her story isn’t close to being over’!” 


Marina was amazing! She engaged well with all of the kids, making adjustments as necessary. She provided so much useful information in her Q&A in addition to phenomenal drills during the clinic. I would sign up for another clinic with her in a heartbeat! – Jamie Teufel in Silver Spring, MD
