Professional Tennis Training - Deni SportsTennis Venue in Sunny Isles Beach, FL

Fluent in both English and Russian, I bring over 15 years of tennis experience to the court. I started playing at age 6 in Belarus, training under several private coaches who gave me a strong foundation in technique, strategy, fitness, and discipline. My playing career included competing in national tournaments, where I developed the skills and mindset I now pass on to my students. I began coaching as an assistant in 2017 and became a full coach in 2020. Since moving to Florida in 2021, I’ve continued helping players of all levels: from beginners learning the basics to advanced students. My lessons are structured, supportive, and tailored to your goals, whether you’re looking to improve fitness, refine technique, or anything else.

"Our son started lessons with Nick to get ready for high school tennis tryouts, and it was the best decision we made. Nick built his confidence, improved his technique, and taught him how to compete under pressure. We’re incredibly grateful for Nick’s guidance.
