Alpha Force is a team of passionate krav maga instructors, practitioners, and trainers who believe in our core values: Integrity, Loyalty, and Strength. We strive to inspire students to find their fighting spirit, empower them with tools and techniques and grow them as individuals able to help and defend others. We are a part of an International Krav Maga association – KRAVolution, which provides further training, support, and instruction to our local chapter. Our International team is spearheaded by world's most sought-after experts: Megan Cohen Berkman, who has practiced and taught Krav Maga for over 30 years; and Jean-Paul Jauffret who has over 20 years of experience and teaches Krav Maga to the French Foreign Legion.

Our Vision: To be recognized as the highest standard Krav Maga school in So Cal that values building confidence and self-defense skills for everyone.


Our Head Instructor, Nancy Stroud began her training with Korean martial arts, including Tae Kwon Do and Soo Bahk Do, and in 2003 earned her 1st Degree Black Belt in Soo Bahk Do. However, she also felt a need for simple self-defense techniques and began training with KMSD in 2002. Enjoying the beauty and traditions of martial arts and the natural instincts and more explosive fighting techniques from Krav Maga, she continued to cross train in both systems until 2007 when she earned her civilian instructor certification. Nancy’s training has taken her all over the world to train with some of the best and most experienced instructors including the founders of IKMF (International Krav Maga Federation). In May 2017, she received her Expert 2 certification in Israel. She is one of the highest ranking Krav Maga instructors in the world and earned her expertise through years of dedication, teaching, and training. Nancy's instructor certifications include civilian, kids, women, third-party protection, and law enforcement.
