Browse our roster of vetted private coaches to find the right fit for you.
Book and schedule your lessons through our platform.
Meet your coach in-person or virtually, and start chasing down your goals!
If you’re looking to message a coach for the first time, go to their profile and click “Send a Message”. A type box will show, where you can enter and send your message. To follow up with a coach you've already contacted, log into your account and find the 'Inbox' tab. You'll see your message history and be able to send another note.
Once you find a coach that fits your needs, go to their profile, select the package you'd like to purchase, and click 'Book Lessons'. Here, you can reserve your desired number of lessons along with the number of athletes who will be training. After sessions are booked, coordinate the dates/times for each session on your calendar - using the calendar is important since this is how your coach will get paid.
Paying AU coaches via cash, Venmo, or any 3rd party is strictly prohibited. AU coaches know this, but their partnership with us is to split all bookings 80/20 - so coaches keep 80%. We use our 20% to help them find clients & manage their business. Without the split, we wouldn't be able to help our coaches & community thrive!
We integrate with Stripe - the largest & most secure payment processor in the US - to facilitate bookings. Paying online is required, and it simplifies the process for our coaches since it helps track their schedule & earnings in one place. If you have any questions or concerns, please contact our support team.
Each coach typically has at least one preferred training location. You can see the location(s) by going to your coach's profile and finding the 'Training Locations' section. If a coach doesn't have locations listed here, you can message the coach to see where they train. Some coaches are willing to travel to clients for lessons, or even meet halfway.
Each coach sets their own schedule for training. You can see a coach's general availability by going to their profile and finding the 'Availability' section - it will list the days and times. If a coach doesn't post their availability, or if your preferred coach doesn't have your desired times available but you want to double check, message them to see if they can work with your schedule.
The AU guarantee (refund policy) has you covered! If you determine the coach isn't a good fit after your first lesson, let us know within 24 hours and you're eligible for a refund. We will also be happy to recommend another coach - be sure to contact our support team.
Our coaches are open to helping athletes of any age and skill level. Please message your desired coach to ensure their skillset fits your needs.
AU was created by former collegiate and professional athletes. We understand the benefits of training with a private coach. It develops discipline, boosts confidence, and provides an undeniable advantage - whether you are just learning the game or looking to earn a college scholarship. All AU coaches are required to pass a thorough onboarding process and we proudly showcase a 10% acceptance rate, so you can trust you're training with the best.
At the end of the day, our mission is to provide athletes with better opportunities to succeed through coaching. You won't find a platform, and group of dedicated specialists, more excited to help you achieve your athletic goals!
