About the coach

Dr. Sandra Harrell is a 5X All-American swimmer and has her Doctorate in Physical Therapy with her Master’s in Exercise Science & Health Promotion. She specializes in coaching you to stay injury-free in and out of the water by optimizing your technique and movement in the pool and in the gym.

She has coached competitive age-group and Masters swimming teams and triathletes, and has over 25 years of swimming experience.

She loves 1-on-1 coaching because she understands that no two people are built the same, therefore no two people move the same. She tailors all of her coaching according to each athlete and their particular biomechanics in order to help swimmers optimize their technique and movement.

Dr. Sandra Harrell is the creator of The Swimmer’s Doc and has over 80K followers that she helps.

Frequently asked questions

What is an online swimming lesson?

An online swimming lesson is a way of learning swimming techniques and skills from a coach or instructor via the internet, using video analysis, live coaching, or online courses. On Skillest, you can receive private instruction with an elite swimming coach without needing to visit a pool in person. Simply record your swimming technique and send it to your coach along with your goals, questions, or any other details to help create a personalized training plan for you.

What are the benefits of an online lesson using Skillest?

Online golf lessons using Skillest offer many benefits, such as convenience, affordability, flexibility, and access to the largest selection of the most talented golf coaches in one place. Through video recordings, side by side comparisons, and conversations you have with your coach, you will receive comprehensive feedback on what you need to improve and how to improve these areas. When you get a lesson on Skillest, you don’t need to schedule a time or drive to your lesson. You can just record your swing and message your coach whenever you have questions.

How do I receive feedback from my coach?

You will receive feedback from your coach through the Skillest app. Your coach will record their own videos with their analysis as well as additional drills to work on and send them back to you inside the lesson. You can watch your coach’s analysis, which may include video, audio, text, or drawings and see the changes and improvements they suggest for your swing. You can also ask your coach follow-up questions you have, and chat with them through the app. You can also review your feedback and track your progress anytime on the app.

What are the different types of lesson plans I can purchase?

Skillest offers a variety of plans and packages available for purchase. You can purchase a single online lesson, lesson packages, monthly subscriptions, or live Zoom lessons. Many coaches also offer video-based courses in addition to one-on-one coaching. Note: Not every coach will offer each type of lesson plan available.

What are Courses?

Whether you're looking to refine your technique, master strategy, boost your fitness, or enhance your mental game, our courses are designed to help you excel in your chosen sport—be it golf, swimming, cricket, basketball, or baseball.
