Introduction
Thank you for visiting — I’m genuinely looking forward to connecting with you. Welcome! I work with swimmers of all ages and skill levels — from first-time learners to advanced athletes refining their strokes. With over 25 years of combined professional and personal coaching experience, and a background as a national-level swimmer representing Southeast Asia, swimming has been a lifelong passion of mine. I offer personalized lessons at your pool — whether it’s in your backyard or a heated community space such as an apartment, condo, or townhouse (as long as lessons are permitted there). For beginners and intermediates, I use in-water, guided instruction to provide hands-on support. Advanced swimmers benefit from a mix of in-water coaching and deck-based feedback tailored to their goals. For beginners and intermediate swimmers, 30–45 minute sessions in comfortably warm water (ideally 82°F or warmer) are ideal. For advanced swimmers, sessions can extend up to 2 hours — particularly for those focused on technique, endurance, or competitive training. I’m also able to teach multiple sessions back-to-back (up to 4–6 hours) in pools maintained between 84–87°F. When working with young children during colder seasons or in outdoor pools, warmer water temperatures (87–89°F) are highly recommended to ensure comfort and consistent progress. Private lessons tend to be the most effective, but semi-private sessions can work well when swimmers are of similar age and skill level. Groups of three or more are possible for intermediate to advanced swimmers, especially in team-style or skill-building formats. Rates 🏊 Individual Swimming Sessions * 30 minutes: $129 * 45 minutes: $182 * 60 minutes: $229 👥 Semi-Private Sessions (Add 30%) * 30 minutes: $167 * 45 minutes: $236 * 60 minutes: $297 Custom rates available for small group training (3+ swimmers) upon request. Please note: most public pools and gyms do not permit outside instructors. If, during the intake form, you select “I'm flexible” under pool access, that indicates you either have access to a suitable location or are open to traveling to one that allows lessons (typically within the Santa Clara City area). I also travel outside of Santa Clara County upon request, with an additional travel fee, to conduct lessons at your preferred pool location. All transactions and communications will be handled with professionalism and respect — and will remain fully confidential between clients and the instructor. Lastly, if you're requesting semi-private sessions, please include each swimmer’s age and skill level to help ensure the best possible match. I look forward to helping you or your swimmer thrive in the water! – Jung

This review is a long time overdue. I took classes with Jung last summer and he really helped me improve all my swim strokes. He is super punctual and very professional. At the end of the last class I left as a lot more confident swimmer than ever before. I hope to take more classes with him in the future to get even better and have no hesitation in recommending him.

Jung at Tri4Swim is a great instructor, he is able to teach and coach swimming skills at any level. He helped me prepare for a Red Cross, Lifeguarding Certification and Swim Pre-test, which included: - Swim 300 yards continuously using front crawl or breaststroke - Tread water for two minutes using only the legs - Complete a timed event within 1 minute, 40 seconds (swim 20 yards, surface dive to 7-10 feet to retrieve a 10-pound object, return to the surface and swim 20 yards back to the starting point with the object out of the water) I was prepared because of Jung's coaching. I completed the pre-test and rescue test with ample time remaining and got one of the fastest-timed event times for the brick retrieval (54 seconds, with a max of 1m40s), and completed the final rescue test within a minute. He worked on stroke refinement, including freestyle, streamline, and breast-stroke, and introduced object retrieval and surface dive. His experience as an aquatics director and head-lifeguard was incredibly valuable, and he had several drills and ways to demonstrate different techniques and improvements. Jung went above and beyond by providing me with a detailed list of the improvements and progress we made during the lesson via text message after our session. He was super responsive and flexible when scheduling. Overall, I was extremely impressed with Jung's coaching abilities and highly recommend him to anyone looking to prepare for the lifeguarding certification, or improve their or their children's swimming skills.

It brings me great joy to extend my sincere congratulations on your successful completion of the LG certification. Your review was a wonderful read, filled with insightful details and kind words. I was particularly impressed by your remarkable improvement in brick retrieval performance and wanted to express my admiration for your hard work and dedication. Ben, Your achievements have not gone unnoticed, A guardian of the pool, you've been promoted. Dedication and commitment, that's your role, For lifeguarding, a task you take on with soul. Success in your future, we all desire, Excelling in all that you truly aspire. A positive impact, you'll leave behind, As a lifeguard, your spirit will always be kind. With heartfelt congratulations, we extend, And good wishes that will always attend. May you shine bright, like the morning's first light, A lifeguard, forever, a guiding sight. -Jung

I’m so glad I found Jung. He was the only instructor that responded timely to my inquiry. He showed me different swimming styles. Now I can alternate between different styles instead of just swimming 1 style so I can work on different parts on my body. Now I am addicted to swimming, I want to go swimming several days a week and it’s all Jung’s fault :)). I can now do swimming and other types of workouts. It’s just so good for my health. I can’t believe that my fear of water has improved so much. Thank you so much, Jung!

Jung is a world class swim coach. My 5 year old daughter has taken 6 private classes with him so far and she has progressed far better than any private class at a dedicated swim school. Jung is patient, inviting and encouraging. He sets the tone for his instruction with a calm demeanor. Moreover, he has a focused plan for our child and manages to hold her attention for the entire duration of the class. I highly recommend Jung to either learn swimming or if you are looking to improve your technique. Jung is highly capable. We plan to work with Jung for years to come. 5/5.
