I am so proud to be a founding partner of Misa Stefen Koller and Ward, LLP.   At MSKW, we share a common goal: to achieve impeccable results for our clients, while simultaneously creating a family work environment for those who join our firm. 


I take great pride in seeing the accelerated growth of our senior associates and making every effort to enhance the skill sets of our senior associates, while simultaneously learning from them.  One of my favorite words is COLLABORATION.  Collaborating with your peers and clients expedites any process and, in my experience, produces the best results for our clients.


Prior to founding MSKW, I was a co-managing partner at a national workers compensation law firm. I provide an aggressive defense for my clients and believe in working quickly to move files to conclusion.  I have filed Writs with the California Court of Appeals and tried numerous cases to conclusion with excellent results.


During my free time, I enjoy spending time with friends and family, eating delicious food, watching/playing sports, traveling the world, and most importantly, spending quality time with the love of my life...my amazing, beautiful wife, Julie. 

I am a Workers Compensation Defense Attorney with over 17 years of California workers compensation experience between the practice of law and claims administration.  I am proud to be a founding partner of MSKW. Prior to becoming an attorney, I was a senior workers compensation claims examiner for over 6 years. Based on my experience level and litigation results, I have been chosen as a panel attorney for multiple Fortune 500 companies. Large corporations have substantial reserves allocated for their California workers compensation claims.  As a defense attorney, I focus on mitigating claims exposure by moving the cases to finalization as quickly as possible. This is done by effective file management, collaboration with the claims team and employer, and aggressive pursuit of case closure through litigation and/or preemptive resolution. 


Outside of work, my passion is my family.  I am married to my amazing wife, Theary, and have two incredible children, Maia and Joshua.  Over the last 10 years, I have become a master Lego builder, Play Doh sculptor, and enjoy spending Saturdays watching them play soccer and basketball.

Family is extremely important here and just like our culture at MSKW, we welcome our clients into our growing family. Throughout practice, I have developed a well-rounded litigation style that will produce the best results for our client from prompt settlements and file closures to litigation of issues that need aggressive defending. I pride myself on being quick to respond to all clients and providing prompt updates.


My undergraduate work was completed at The University of San Diego where I graduated with a Bachelor’s degree in Business. I had the amazing opportunity to play college football under the great quarterback and coach Jim Harbaugh, where we took home 2 conference championships. I truly enjoyed channeling my competitive nature on field, in the class room and today, in the court room for my clients. I was honored to graduate as valedictorian at Western State College of Law in Fullerton California. I have been practicing in the area of worker’s compensation defense since graduating in 2011.


Outside of work, I love spending time with my wife, Jill, our endlessly energetic sons, Nolan, Brycen, our newborn, Hadley, and our ridiculously cute dog, Lexi (yeah it’s a Full House over here!). I am a borderline fitness fanatic and with a little help from caffeine, get to the gym daily before the sun rises. My wife tells me this doesn’t help my caffeine addiction and I agree, but I know my discipline helps me be able to spend more time with my family and helps justify my peanut butter obsession.


In practice and in life I believe that Arthur Ashe said it best: “Success is a journey, not a destination. The doing is often more important than the outcome”

I joined the MSKW family in January of 2017, bringing with me over six years of experience as a workers’ compensation defense attorney.  I’ve represented insurance carriers, self-insureds, and CIGA in all aspects of Workers’ Compensation.  I pride myself on prompt and productive communication with clients, which I believe is the cornerstone of my tenacious and effective representation.  


I earned my Bachelor’s degree in History from the University of Colorado and my Juris Doctorate from Southewestern University School of Law.  While at Southwestern, I was a Lead Article Editor of the Southwestern Journal of International Law and I interned as a Certified Law Student conducting dozens of preliminary hearings with the Los Angeles District Attorney’s Office.


When not in the office, I enjoy watching sports, playing basketball, barbecuing with family and friends, and backpacking into the wilderness with my wife, Alexey.  The best night’s sleep one can have is in a tent in the middle of the woods. Just make sure you have a reliable sleeping pad.

I join the MSKW team with extensive workers compensation experience, defending insurance carriers, third party administrators, and self-insureds. I believe in effective communication, strong analytic skills, and resolving cases expeditiously, while limiting exposure and litigation costs for my clients. I went to UCLA where I obtained my Bachelor of Arts in Sociology, and received my Juris Doctorate from Chapman University School of Law. During law school, I interned at the City Attorney’s Office and participated in the Domestic Violence Clinic, where I learned how to apply the law in practice and advocacy.

Outside the office, I love to spend time in nature, whether hiking mountains, going to the beach, or having unplanned adventures with my amazing husband and our two rescue puppies, Benji and Satie. One of my favorite things to do is experience new places, cultures and countries, and I have recently traveled to Australia, Croatia, New Zealand, Aruba, and Italy. I am passionate about fitness, meditation, and overall wellness and aim to achieve balance in my everyday life. This could mean spending quality time at home or with family and friends, going to music concerts, trying new local restaurants, or sometimes sky diving, bungee jumping, and cliff diving (sorry mom).

I am excited to continue this adventure with the MSKW team and to provide an aggressive, efficient, and tailored defense for all my clients.

Alan Sagherian

We all have ups and downs, but I think that a fresh perspective can really minimize the downs and maximize the ups, and I try to bring that positivity to the workplace.  Just because we call it “work” does not mean that it must be work. 


I was born and raised in Los Angeles, where I graduated from UCLA with a degree in History for my undergraduate education before graduating from Loyola Law School.

I have been defending Workers’ Compensation claims since 2011, and I instantly felt that the industry was a good fit for my personality and willingness to work with others.  Frequently the most effective defense of a claim will rely on relationships between attorneys, Judges, secretaries, really everyone involved in a case, and I have used my irresistible charm to effectuate results for my clients, from quick closures to aggressive litigation, where warranted. 


I have spent a significant amount of time defending complicated continuous trauma claims with multiple employers and carriers, which has resulted in keen analytical skills for those types of claims, and increased scrutiny for more straightforward claims. 


I believe that balance and perspective are critical aspects for a successful existence, both inside and outside the office.  To that end, I spend a lot of my free time playing guitar, trying to live out my dreams of being a heavy metal superstar (albeit in a part-time capacity).  Other than that, I take advantage of the amazing Southern California climate by getting to the beach as often as possible in the summer, and going snowboarding as often as possible in the winter.  

Katie Rooney


Katie’s been a fixture on the work comp scene since 2004 providing defenses to various clients including professional sports teams, TPAs and school districts. After managing an Orange County office for three years,  she will be heading back to her home board in San Diego.

In her spare time, she enjoys daily beach walks with her yellow lab Carmine, and staying local to the Encinitas beach community with her boyfriend and their three dogs.

She’s been known to dabble in the occasional endurance event, competing in numerous marathons, half marathons, and triathlons including Ironman.

When not beaching, exercising or hanging out with the dogs, you’ll usually catch Katie with a book in hand and an ever-growing Amazon book list.

I have spent much of my practice in workers’ compensation defense, working with insurance carriers, third party administrators, and self-insured employers.
