About Our Instructors


Owner, Master Instructor


Motto: "The ultimate aim of martial arts lies not in victory or defeat but in the perfection of the character of its participants."


At the age of 8, Neil began his martial arts career learning karate under Sensei Takahashi, who went on to award him with his brown belt. He wrestled from 4th to 10th grade for Amityville School District, where he also competed in many point sparring matches.


Neil then learned and become an instructor of krav maga under the watchful eye of Rhon Mizrachi for the Krav Maga Federation at the Flagship School in Manhattan. Neil is very thankful and appreciative to have had the pleasure to work with Rhon Mizrachi, as he inspired Neil to become the instructor and martial artist he is today.


Neil went on to test for his brown belt in Israel in front of a krav maga committee including Grandmaster Hiam Zut, the highest ranking krav maga instructor in the world. As part of the first group of Americans to do so, he's known as a true pioneer to the sport!


Other accomplishments include being a volunteer fireman for six years, a blue belt in jiu jitsu under Matt Serra, and a 3rd Dan black belt under the PKF Federation, to name a few. As a master instructor, he has helped multiple people become champions in the WKA, USMTA, USKBA, ISK, and PKF. Neil is always looking for new ways to give back to the community! He opened Strike First Fitness and MMA of Smithtown, NY so people could do what they love in a fun, safe environment and simultaneously reach their individual goals.

Martial arts and combat sports have been a major part of Dave's life for the past 10+ years. He started wrestling at the age of 14, and at age 16, started studying a mixed system of traditional martial arts including Tae Kwon Do, Japanese Jiu Jitsu, Ja, Hanbo Jutsu, and Sambo. This gave him his first introduction into the discipline behind the training of martial arts.


Soon he met some very influential people through friends, who convinced him to try kickboxing and MMA despite the injury that ended his wrestling career. He started training kickboxing in 2007 and made his amateur debut in 2008. 


Aside from being a veteran amateur MMA competitor and a 1st degree black belt in American Style and Oriental Style kickboxing, other notable accomplishments include being a 3x NYS Kickboxing Champion, USKBA San Da NYS Champion, PKF NYS Kickboxing Champion at both 175 and 189 pounds, and PKF Northeast Muay Thai Champion. Dave is also a BJJ competition medalist in white and blue belt divisions. He wrestled in college and is a registered fighter under the WKA, PKF, and New Jersey Athletic Board.

Born and raised in Smithtown, Matt fell in love with martial arts at the age of 12. In addition to playing football and running track at Smithtown West, he started taking Kempo karate and earned his brown belt with three stripes. Looking to expand his knowledge of martial arts, he decided to join an MMA gym. It was there where he met his current instructor Neil Doyle. Matt feels he has never been in better shape -- he has lost more weight and gained more muscle and endurance than he thought possible. He is proud to say that after many years as a martial arts student, he is becoming more of a true martial artist every day. The most rewarding part of his day is teaching and helping people reach their fitness goals.
