About Andover National Karate

Welcome to Andover National Karate, a trusted martial arts school proudly serving the north metro area for more than 30 years. We are committed to helping students of all ages build confidence, discipline, and the skills needed to protect themselves while having fun and staying active.

Our facility is designed with your comfort and safety in mind. We offer approximately 1,900 square feet of training space equipped with 1-inch padded mats to ensure a safe and comfortable learning environment. Parents can observe classes from our glass viewing area, and our building includes two bathrooms with changing areas. We provide ample parking with handicap-accessible spaces, and our climate-controlled facility allows for enjoyable training year-round.

At Andover National Karate, we believe strongly in community involvement and giving back. Over the years, we have had the privilege of teaching self-defense lessons to students in local schools across all grade levels. We have worked with Constance Church and the Girl Scouts of America to provide empowering self-defense workshops and demonstrations. Each year, our students proudly participate in the Andover Family Fun Fest parade and perform a live karate demonstration to showcase their skills and teamwork.

Our school has built a strong reputation for excellence in competition. Since 2003, Andover National Karate has consistently earned first place or runner-up honors among 20 schools in both form and sparring at the National Karate Sport Karate Challenge, previously known as the Team Championships. Andover National Karate is proud to have Black Belt students competing locally in the North Central Karate Association (NCKA) circuit and placing 1st place overall consecutively over the years in both sparring and form.

Andover National Karate is dedicated to helping every student reach their full potential. Our classes, ranging from 30 minutes to one hour depending on age and belt level, are designed to challenge and inspire students of all abilities. We welcome students with disabilities because we believe everyone deserves the opportunity to learn self-defense and gain confidence. Belt promotions are earned through skill development, hard work, and consistent attendance. Class sizes vary up to 30 students, allowing for personalized instruction and group motivation. Each class will always have two instructors present, with additional instructors added as class sizes increase.

We are open Monday through Friday from 4:00 PM to 8:30 PM and on Saturdays from 9:30 AM to 1:30 PM. During the summer, we also offer daytime classes on Tuesdays and Thursdays from 11:30 AM to 12:30 PM. Whether you are looking for a fun and structured activity for your child or a way to stay fit and relieve stress as an adult, karate is a powerful way to grow stronger physically and mentally.

Join us today and become part of a positive, supportive community that values discipline, respect, and personal growth. We look forward to helping you discover your strength, build your confidence, and achieve your goals at Andover National Karate.

Meet our Leadership Team & Instructors

Ms. Sue Lomasney, the Owner of Andover National Karate, brings decades of experience, leadership, and passion to our school. She holds a 7th-degree black belt.

Ms. Lomasney began her martial arts journey in November 1981. She earned her 1st degree black belt in the summer of 1986 and committed herself to both personal excellence and teaching others. After moving to the Twin Cities area to pursue a degree in Physical Therapy, she joined National Karate in 1987 and has been training, competing, and instructing ever since.

An accomplished competitor, Ms. Lomasney is a multi-time Overall Sparring Grand Champion. She has traveled across the United States, winning numerous titles and earning the prestigious Diamond Ring from the Diamond Nationals Karate Championships. In addition to her karate expertise, Ms. Lomasney is a certified Krav Maga instructor with kickboxing experience. She has been featured in the Star Tribune for her competitive success and recognized as one of the top martial artists in her field. Her competitive background uniquely positions her to lead in both martial arts instruction and school direction.

Her teaching philosophy is grounded in inspiring every student to achieve more than they thought possible, whether that means growing confidence, improving physical ability, or developing self-discipline. She firmly believes that the lessons learned in martial arts carry over into all areas of life. With over 40 years of instructing and 45+ years of training, Ms. Lomasney fosters a culture of excellence, respect, and personal growth.

Under her leadership, Andover National Karate remains dedicated to delivering high-quality instruction, welcoming all ages and abilities, and cultivating a supportive community where students thrive.

Brian Sherve is the Director and Head Instructor at Andover National Karate, where he brings decades of dedicated experience and a passion for teaching. He holds a 6th-degree black belt and began his martial arts journey in 1997 at age 8 at the Coon Rapids National Karate location under the direction of Ms. Sue Lomasney. In 2002, shortly after being promoted to 2nd-degree black belt, he started teaching and hasn’t looked back.

Mr. Sherve loves leading students who are excited to compete in tournaments. His teaching philosophy centers on creating an environment where students eagerly return to class multiple times per week. He believes one of the best gifts he can give his students is his genuine self, his energy, guidance, and commitment. He excels at pushing students to achieve more than they ever thought possible.

Detail-oriented and focused, Mr. Sherve ensures that his students do more than perform techniques correctly. He guides them to understand why and how those fine details make them stronger, faster, and more effective in both training and real-life self-defense. Under his leadership, Andover National Karate remains a place where discipline, growth, and excellence meet.

Mr. Sam Wiggins is an Instructor at Andover National Karate, bringing both passion and precision to every class. He holds a 3rd Degree Black Belt and began his training in 2012 at just 6 years old under the instruction of Ms. Sue Lomasney and Mr. Brian Sherve. After earning his 3rd-degree black belt in 2022, Mr. Wiggins began his teaching career at both Andover and Ramsey National Karate.

What People Are Saying About Us

Mimi Petroske

We have been here several times to watch our grandchild learn karate. The instructors are very good, especially when dealing with larger classes. They have patience and encouragement when working with the students. We look forward to seeing the progress our grandchild makes throughout the coming months.

Bruce

My son attended Andover National Karate and earned his black belt thanks to hard work, discipline, and excellent instructors. They’re firm but fair, and fun as well. I was so inspired by my son’s success that I joined up and have been attending for several months. I have a long way to go, but I’m becoming more flexible, my balance is improving, I’m learning a lot, I’m gaining confidence, and I feel better physically. I can’t say enough good things about the instructors! My only regret is not starting years earlier.

Patrick Hobot

I was an NK student back in the 80s/90s and wanted a place my son could train. We tried several places with varying success and affection, but we finally found NK Andover. Ms. Lomasney and Mr. Sherve are top-notch instructors, prolific champions in their own rights, and have a really good understanding of the stages of development for young people. While friendly, they are very honest and direct instructors who hold high expectations for the students. It’s not “trophies for everyone”- you have to put in the time and know your stuff, but you or your child will be better for it. Proud parent of a 2nd degree BB.

Sierra Renkert

The instructors are great and truly care about your progress in a physical aspect but also with self confidence, control, and discipline. There are opportunities for tournaments and engaging with the karate community. I have been attending at this studio regularly for 8 years now and can say that karate has made my life better. I have built lasting relationships with the people around me and I am so grateful karate is part of my life
