In-House Training Reviews

Salons across the UK and USA have brought TGB education into their own space with our In-House Training. Here is what their owners and teams had to say about the experience.

We just completed our first TGB in-house training with Sarah, and the experience exceeded our expectations. From the moment she arrived, Sarah was incredibly professional, organised, knowledgeable and prepared. She arrived right on time and brought so many products, tools and educational materials for our nail technicians to learn from and practise with.

What impressed us most was the level of detail in her education. She answered all of our questions and carefully explained proper product application, what to avoid during application, how to prevent common mistakes, and how understanding nail anatomy and nail health can help us achieve safer, cleaner and longer-lasting results.

Another huge plus was that Sarah was able to provide the training in both English and Spanish. Having a bilingual educator made such a difference for our team. She made sure everyone fully understood the information, felt included, and was comfortable asking questions in the language they felt most confident speaking.

Sarah has such a wonderful personality. She is sweet, patient, approachable and an excellent educator. She created an environment where our entire team felt comfortable asking questions, learning and practising. By the end of the training, our technicians felt more confident, motivated and excited to improve their application techniques.

We are 100% confident that we are going to see a difference in the quality and consistency of our work after this training. Our only wish is that the course could have been even longer. There was so much valuable information, and we wanted to keep learning.

Thank you, Sarah, for sharing your knowledge, professionalism, patience and passion with our Nail Garden team. This training was an investment in our education, our confidence, and the quality we provide to our clients.

We had such an incredible experience with Sarah from The GelBottle. From the moment she began training, it was clear how knowledgeable, skilled and passionate she is about her craft and the brand as a whole. Her attention to detail is exceptional, and she took the time to work closely with each member of our team, making sure everyone understood not only the techniques, but the reasoning behind them.

One of our technicians even said that she learned more from Sarah in one day than she did during her entire time in nail school, which really speaks to the quality of Sarah's education and the way she teaches.

What we appreciated most was that Sarah's training went far beyond simply becoming a highly skilled nail technician. She talked about the importance of the entire client experience: how you present yourself, attention to detail, professionalism, communication, customer service, and how to build lasting relationships with clients. She really emphasised that being an exceptional nail technician is just as much about how you make your clients feel as it is about the quality of your work.

Sarah was patient, engaging, encouraging and incredibly generous with her knowledge. Our team walked away feeling more confident in their technical abilities and inspired to continue improving both their craft and the experience they provide to every client. We are so grateful to Sarah and The GelBottle for investing this level of education into our team. Having her at Bower was truly invaluable, and we cannot recommend her enough.

We had such a great experience with our in-salon training at both locations. It brought our entire team together and created a fun, collaborative learning environment. Every technician walked away with new professional tips, techniques and product knowledge that they can immediately apply with their clients.

The one-on-one coaching was especially valuable, helping build confidence and giving each team member personalised guidance based on their individual needs. We also learned new services and techniques that we can now confidently offer, creating more opportunities for increased bookings and continued growth for both our technicians and the salon.

A huge thank you to Maddie and Sarah, they were absolutely amazing. They were knowledgeable, approachable, incredibly helpful, and made the entire day so much fun. They created an environment where everyone felt comfortable asking questions, learning and growing.

The training was engaging, informative and incredibly worthwhile. We truly appreciate the time, expertise and encouragement, and we are excited to continue building on everything we learned. We highly recommend this training to any salon looking to invest in their team's education and success.

Sarah has been an exceptional partner in helping us successfully launch builder gel services for MiniLuxe studios in both Boston and Los Angeles. Her training is clear, thorough and highly effective. Our teams left feeling confident and prepared, which translated directly into strong service adoption and meaningful revenue growth.

Beyond her technical expertise, she is a true professional and a fantastic representative in the field. She consistently shows up organised, supportive and deeply committed to the success of the teams she trains.

She also goes above and beyond in her follow-through, regularly checking in and even stopping by our studios to offer additional support while in town for other trainings. Quite honestly, the brand is incredibly fortunate to have her. She elevates the experience far beyond what you might expect.

As a fellow educator and co-owner of Star Touch Agency, education is a priority for us. Sarah came to teach BIAB™ to our team of celebrity nail artists and they all raved about Sarah and about the class. We learned prep, application, time saving tips and more. Thank you.
