Camp Details

Join Coach Mastebroek at STREAMLINE Texas Swim Camps to experience a unique technique-focused swim camp. You will get lots of opportunities to watch yourself swim in both above- and underwater video and use this visual feedback to improve your technique. You will get an understanding of why Olympians are so fast and learn from their technique mastery. Example contrasting a developing swimmer’s freestyle technique to that of an Olympic champion:

Camp STREAMLINE is open to children ages 7-16 that know how to swim. This means that lower-level rec swimmers with little or no competitive experience as well as highly competitive club swimmers are welcome. At STREAMLINE we group campers by age and level. Each group enjoys a low camper-to-coach ratio and receives appropriate programming based on needs. The younger/lower-level groups typically focus more on technique basics and older/higher-level groups on technique refinement.


At each day of each camp session, we use four 40” monitors on the pool deck. We set up four above- and underwater cameras around the pool that feed into the four monitors. This allows for non-stop video recording with delayed playback which accelerates learning tremendously. SWIMMERS LEARN QUICKER WHEN THEY CAN WATCH THEMSELVES SWIM. The way this works is: The camera records ‘life’ and nonstop, but the playback is delayed, by about 15 seconds. This allows swimmers to perform a swim skill in front of the camera, climb out of the water, and watch on the monitor what they just did 15 seconds earlier. They then go back in line and repeat until the desired improvement is achieved.



With four cameras at different spots in the pool, we can have four groups of campers work on technique with video feedback at the same time. This allows for individualization: At each of the four camera stations, small groups can work on skills—whether it is a stroke , start, or turn skill—that fit their needs without having to do the same thing as the other groups. Moreover, additional individualization within the small group is possible at each video station.



We are excited to use new software that splits the screen into four quarts which allows for quadruple visual feedback. This is especially useful for starts and turns practice. The speed and the non-repetitive nature of starts and turns make it harder to ‘catch’ imperfections when you watch yourself perform the skill. Our new software solves this problem by allowing you to watch yourself perform the same skill four times in a row.




Campers attend daily classroom-type sessions involving presentations and watching swim videos. We own an extensive video library of swim technique videos, including split screen video showing above- and underwater action simultaneously. The advantage of our split screen videos is that we no longer have to toggle between underwater videos and above-water videos, which makes the teaching and learning process more efficient. In addition to learning about technique and based on age/level, campers also learn about other swimming-related topics such as race strategies and breathing strategies.



A full-day camp wouldn’t be complete without some down time and games. Typically, younger campers need more down time than older campers due to variations in attention span. Games may differ per location depending on equipment available. For example, campers have access to a water obstacle course (see picture below) at the Pleasant Glade Grapevine pool, but not at the other locations. At other locations different equipment will be available.



Our full-day camp sessions include a visit by an Olympian. The visit includes a motivational speech with a Q & A round and a viewing of his/her Olympic race. Campers can have their picture taken with the Olympian and obtain an autograph. Some Olympians bring their Olympic medal(s) to camp and allow campers to wear them in the picture.



Campers have access to swim-specific equipment, such as underwater mirrors, fulcrum paddles, and hip blades to help grasp technique concepts.


All campers (all sessions) receive a STREAMLINE t-shirt, videos of themselves swimming, and a stroke recommendations report (included in camp fee).

Mission Statement

We deliver a unique camp experience that aims to improve kids’ swimming techniques in order to become better swimmers and prevent swim injuries. Moreover, we want to ignite or deepen the passion for swimming in our campers.


At STREAMLINE we believe that proper technique is the basis for long-term success in the sport of swimming. We believe in slow deliberate technique practice and breaking down skills and strokes in components to teach through progressions. 

In addition, we acknowledge the importance of science and how it has accelerated the development of swimming, especially in the new millennium, and believe it is paramount to stay current with scientific development in swimming in order to remain competitive as a nation at the highest level.


STREAMLINE started out as a fun 2-week project in the summer of 2010, when founder and former European Champion, Marieke Mastebroek, flew her old Dutch coach, Anton Koekkoek, and a world-class biomechanic, Wieger Mensonidus, in from Europe to work on technique with some of the fastest club swimmers in North Texas.

Consequently, many swim parents showed interest in this type of technique training for their swimmers. At regular team practice, time constraints and large group sizes often stand in the way of thorough, deliberate technique work. STREAMLINE camps promised to fill this gap.

The following summer, STREAMLINE offered its first series of technique swim camps for kids at all levels—from rec swimming to the highest level club levels. All of the eight one-week camp summers offered that summer sold out. STREAMLINE was on the map as a high quality, technique-focused, high-tech swim camp, perhaps the first and only one in its category.

STREAMLINE continued its success the following years and added several Elite sessions featuring Olympic guest coaches, including International Hall of Fame Coach, Paul Bergen, and Cullen Jones’ coach, Ed Nessel.


Coach Mastebroek

Coach Mastebroek is the founder and director of STREAMLINE Texas Swim Camps and is regarded as one of the top stroke technicians in the area. She has developed a stroke analysis system which she applied to perform over 500 frame-by-frame stroke analyses with the aid of underwater video and motion software. Coach Mastebroek has had the privilege to work with and learn from American as well as European Olympic Coaches whom she flew in to guest coach at her STREAMLINE camps. In addition, she has traveled to Europe to learn from elite biomechanics at the Dutch Olympic Training Center in Eindhoven, the Netherlands.

Coach Mastebroek is a former elite swimmer and holds multiple titles, among them:  European Champion (Athens, Greece- 1991), Dutch Record Holder, and World Championship Finalist (Perth, Australia- 1990).  At one point she was ranked number one in the world in the 50 freestyle.  As a member of the National Swim Team in the Netherlands, she traveled to compete and train in more than 20 countries.  In 1993, Mastebroek was recruited by SMU, where she was NCAA Division I All American, won several SWC and NCAA Division I medals, and ended her career with a 2nd place team finish at the NCAA Division I Championships in 1996.

Coach Mastebroek is currently the Head Coach of the Coppell High School swim program, which she has been rebuilding since her start with the program in 2016. She also has years of club coaching experience coaching swimmers at all levels, from novice to state and national levels.
