Experienced tutor in Swimming in Orange, Mark offers private lessons tailored to your needs.

Coach Mark was my HS coach as well as mine and my sons club coach. He is a master of his craft and works persistently to support his athletes. Also, coach is himself a student of the sport by always staying up to date on the latest in the world of swimming whether it is news, training, technique, performance, or anything else related. My son started competitive swimming in the fall of 8th grade. Over the course of the next 4 years, exclusively coached by Mark, he swam at Jr. Nationals, made CIF all 4 years, was a 2x All-American, 1x individual CIF champion, 2x individual CIF Runner-Up, 4x 1st team All-League, 1x League MVP, and 4x Academic All-American. After HS he attended Princeton and was offered a roster spot with their D1 men's swimming program. Coach Mark is exceptional with details as evidenced by his workouts and stroke work. He is the epitome of commitment and dedication to excellence, bar none. Last, but not least, his relationships with athletes and their families transcend pool deck.

Coach Tierney understands what each swimmer needs and tailors the training to individual needs. He also displays a great deal of patience with the swimmers as they learn and grow in the sport.

Coach Mark helped our daughter develop her swimming skills from the time she was 8 years old barely making a 50 yard swim to when she was 15 years old swimming Individual Medley swims and making cuts in senior swim meets. Throughout her years with Coach Mark, he was always a positive influence on our daughter. He was encouraging whenever she was having bad days and would celebrate her successes with her. He always had a way of being able to coach and teach at a level my daughter understood no matter what age she was. Always remained professional. Highly recommend Coach Mark.
