About Our Teachers

Scott Mastin, Kyoshi 7th Dan

(pictured with his son Brandon 7/14/12)

Scott Mastin Sensei, was promoted during his visit to Okinawa to the rank of Roku Dan (6th degree black belt)  with a teaching title of Renshi. He became the youngest American to ever be awarded this rank by Soke Nagamine. On the same trip in November 2010, he had the opportunity to teach at the Honbu dojo that was established by O’Sensei Shoshin Nagamine in 1953. This was a tremendous honor and a life changing experience.  Mastin Sensei has made several trips to Okinawa to further his training.  During the 2017 visit to Okinawa, Mastin Sensei  participated in the promotion testing and was award the Rank of Nana Dan (7th degree blackbelt) with the title of Kyoshi.

He was introduced to karate and martial arts at age 4. Mastin Sensei became more serious about his study of Matsubayashi-Ryu during his teenage years, and began teaching at age 21. In addition to Matsubayashi-Ryu, Mastin Sensei is trained in Yamani Chinen-Ryu (Okinawan weapon arts) and has studied Tai Chi. Mastin Sensei  was a direct student under Soke Takayoshi Nagamine, and is licensed to teach by the World Matsubayashi-Ryu (Shorin-Ryu) Karate-Do Association .  Mastin Sensei has been fortunate to have trained in many of the Matsubayashi Ryu dojo’s in Okinawa. Mastin Sensei  began teaching in the early 90’s and took over the Silverton dojo in 1995.  Mastin Sensei founded the Mastin Dojo in 1999.

Mastin Sensei received all of his rank from Okinawa. His first and second Dan were reissued by Soke Nagamine. ( they originally came from a different Okinawan instructor). Nagamine Sensei promoted Mastin Sensei for the ranks of San Dan through Roku Dan with the title of Renshi.  The latest rank of Nana Dan with title of Kyoshi was issued during his 2017 trip to Okinawa by the WMKA testing board.

Even though Mastin Sensei still works during the day with his outside career. He still teaches many of the classes at the dojo. “Teaching and helping others is my passion” –  “You must lead by example”  – “Never ask your students to do something that you can not do yourself” are all statements that he tries to instill in all of his black-belts and instructors.

Mastin Sensei has written 4 books with criteria specific directions for each belt level. The instruction and books cover all age groups from the 4 year old Little Ninja Student to the Blackbelt Adult Students.

Notes for Curtis Mitchell about his late brother, Sensei John Mitchell


On behalf of my family, I would like to thank you so very much for your remarks at the service for John. You helped us get through what was undoubtedly the most darkest day in our lives. As you console us, allow me to console you for the loss of your best friend. Your friendship meant the world to Johnny. He cherished every moment of it. When Johnny mentioned your name, it was always “My friend Scott” or “Me and my friend Scott.” And believe me he spoke of you often! The immeasurable time he spent with you, your family and the students at the dojo was so gratifying to him. Your final tribute to John was sending your black belt into eternity with him. It was the ultimate final honor by a truly loyal friend and Sensei. We should all have a friend like my brother John had in you!

Again, Thank you so very much.

Curtis Mitchell


“For the past 51 years we have had the blessing and pleasure of being related to Johnny. He was and will remain a very special part of our family. His passing has left a hole in our hearts that will never be filled. We are forever grateful to each and every one of you for the outpouring of love, respect, kind words and honor expressed at his memorial service. You gently confirmed what we knew for the past half century…that he was indeed a special man, son, brother, uncle, friend and Sensei. His smile touched many people.

TAI CHI – Chief Instructor

Dr. Larry C. Bobbert has been practicing martial arts for nearly 50 years. He’s studied several styles, has Black Belts in Aikido (Nidan), rank in two styles of karate and arnis and 25 years practicing Tai Chi that included two trips to China. He includes Qi Gong (breathing) which he believes is an integral part of both aikido and tai chi. For several years Dr. Bobbert taught Stress Management through Tai chi Exercises at Eastern Kentucky University. He began in Ohio at the West Chester Activity Center with Partners in Prime. Currently he teaches at the Countryside YMCAs in Lebanon, Landon and Otterbein; Mount Pleasant Retirement Village in Monroe and Gracetree Yoga Studios in West Chester. He developed No Nonsense Self Defense for young people who need to cope with bullies and be aware of adults who might harm them. The process began when he was approached to develop training for Public Safety personnel. While watching young people practice martial arts Dr. Bobbert became aware that it would take them years to be proficient enough to defend themselves. Teens, preteens and adults need techniques that are simple to learn, effective in emergencies and don’t take years to master. He developed No Nonsense Self Defense and added classes for those who need to protect others in Simply Self Defense – Protect and Control. He earned his Doctorate at the University of Cincinnati, Masters at Wayne State University and BS at Clarion University. He has given presentations in 34 states and 4 continents.


Ebony Laster
I am Ebony Laster, Cincinnati native.   Mother to one son and one adorable pit bull.  I own a Massage and Facial spa,  Empowering Touch.  I am a licensed massage therapist since 2017 and certified yoga instructor. I am an advocate for being proactive against the effects of stress and old age.  My mission is to inform the community of self care practices and healthy daily habits.
My passion for healing came early on as a State Tested Nurse’s Assistant for 11 years.  I saw how poor habits and old age can take a toll on the body.  My Dad and his wife also dealt with managing pain so I saw effects of injuries/chronic illnesses on a personal level as well.  I decided to become a Medical Massage Therapist and try a holistic approach to heal chronic ailments. Once I had one foot in the industry, so many different modalities called to me.  I am now certified in Manual Lymphatic Drainage, Thai massage for the table, and Yoga RYT 200.   I enjoy showing the body can restore itself, sometimes it needs an extra push.
