Don't just take our word for it though. Together we've achieved Certified Microsoft Partner status which is reserved for IT companies demonstrating excellence in implementing Microsoft technologies.

Rather than existing in a specialized IT bubble, we communicate with our clients in positive way without blasting you with IT jargon.

Armed with a degree in economics from Columbia University, a list of certifications and several years of civilian IT experience, Andrew joined Centarus as an IT Consultant.

Savita Sahi

General Manager

Hobby: Painting


Centarus cofounder Savita Sahi is an entrepreneur at heart. She managed all aspects of her family’s San Francisco restaurant by the time she was 16 years old, then earned a degree in education and set about transforming local schools.

Manuj Rattan

IT Guru & Service Delivery

Hobby: Family & Career


Manuj sees life at Centarus as a roller-coaster ride — one he enjoys immensely and is more up than down. He revels in learning something new every day, whether about the technology, the client company or the person on the other end of the phone. Manuj has been in IT for more than five years, after earning degrees in computer programming and business administration, as well as working at several technology companies. In his free time, he researches old support tickets to figure out what he could have done better.

Yashwant Thakur

IT Guru & Centralized Services

Hobby: Mountain Climbing


While playing electronic games as a child, Vincent always concentrated more on how the games were running than on the actual playing. Paying close attention to background and process led him to bachelor’s and master’s degrees in computer application. Following work for several different MSPs, he joined Centarus, focusing mostly on backups and maintenance of services. When he is not serving as a member of clients’ remote IT team, he may be found meditating or doing yoga.

Jan Mcwiliams

Office Manager

Hobby: Hiking & Swimming


Jan found the perfect place for her extreme perfectionist tendencies as the office manager and bookkeeper for Centarus. The company’s resident “non-techy,” she enjoys doing everything there is to do to keep things running smoothly for both clients and employees. In her spare time with family, she is in or around any water she can find.

Manish Mahajan

IT Guru

Hobby: Nowadays, he enjoy spending time with his wife & Son


With a lifelong fascination with technology, a degree in computer science and experience working for Dell, Manish loves putting his knowledge to work finding solutions for Centarus customers. He believes he was born a cricket fan and even played at the interstate level while in school. Nowadays, he enjoys spending time with his wife & Son.

Dale Roberts

IT Guru & Founder

Hobby: Playing Guitar


Dale discovered his penchant for technology while working on radars during his time in the US Navy. He built on that experience with stints at tech firms, both nationally and internationally, eventually founding Centarus to help small companies leverage technology to grow their businesses. It’s his intent to prove to clients that their technology is not all that scary — as long as you have the right tools and support. If he weren’t in tech, Dale is pretty sure he would be a professional star-gazer.

John Warno

Sales & Systems Engineer

Hobby: Sailing


A California native with a degree from the Academy of Art University, John brings a broad skill set to Centarus. As a sales and systems engineer, he specializes in compliance and security issues, offering clients more than 15 years of experience in customer facing roles and information technology — seven of which were spent working with all aspects of MSPs. When not working with the good people of Centarus, John enjoys sailing.

Rajinder Singh

IT Guru

Hobby: Punjabi dancing


When becoming a professional cricket player or dancer didn’t seem possible, Raj’s father steered him “to be part of something with more of a future.” He studied IT in college and has been working in the industry ever since. A native of Chandigarh, India, he enjoys learning something new every day working at Centarus, where he helps clients solve every kind of IT problem. Raj enjoys cricket and watching movies, but most of all, he loves making his one-year-old son laugh.

Mark Neuman

IT Guru

Hobby: Mountain Biking


Mark found his penchant for IT in an internet café in Chicago. He brought people skills, management experience and the ability to learn quickly to his first job in the industry. He brings those same skills to Centarus — along with 20 years of experience. Educated in the U.S. and Israel, Mark likes working with diverse types of people, including everyone from CEOs of companies to front-line workers. He is based in Prescott, Arizona, where he is an avid mountain biker.

Mariana Castillo

IT Guru & Dispatch

Hobby: Gardening & Cooking


A native of Costa Rica, Mariana always thought she’d wind up working in psychology, going as far as earning a university degree in the subject. But an early employer had a different idea, training her in IT support. Along the way, she found she really liked it. She’d enjoyed psychology because she was able to help people, and she discovered that in IT, she can do the same thing. Now with more than 13 years of experience in IT support and customer service, Mariana puts her skills to work as a self-proclaimed “IT fairy,” working closely with clients to solve all their problems. In her spare time, she enjoys gardening, cooking and spending time with her little dog, Pippa.

Jason Hiller

IT Guru & Data scientist

Hobby: Wood Working


Jason’s life is all technology, all the time. It started in the 1980s when his parents brought home a Commodore 64, and he was hooked. Based in Surprise, Arizona (yes, that’s the name of the town), Jason loves that, in technology, everything has a logical, rational conclusion — anything can be done; you just have to figure out how. He enjoys empowering Centarus clients with technology to save their time and increase their productivity.

Braxton Herring

IT Guru

Hobby: Crafting & gardening


At age 7, Braxton started installing programs on an old XP computer. As his family got new computers, he would tear them town and rebuild them, until it grew into a career. Based in Arizona, Braxton enjoys learning new processes and working with new technologies. He provides remote tech support to Centarus clients, whom he finds particularly easy to work with. Outside of work, Braxton is passionate about music and gardening, and he loves cows and sheep.

Ryan Barba

IT Guru

Hobby: Cars & Coral-Reefing


Ryan is a San Francisco native whose uncle got him into fixing computers when he was growing up. When it came time to choose a career, Ryan realized he already had the skills and mindset to pursue IT. Known for his easy smile and laughter, he loves the problem-solving and “curve balls” in his day-to-day work for Centarus’ clients. When not at work, Ryan has an eclectic mix of hobbies, including showing cars he’s fixed up, “coral-reefing” with the saltwater coral-reef tank in his home, and spending time with his family, including his dog, a Malti-Shitz named Casper.

Scott Hanson

IT Guru

Hobby: Sailing


Growing up in Southern California, Scott was the first kid in his neighborhood to get a computer. He was always analytical and interested in science and the future, so he earned a degree from UC Santa Barbara in computer science and engineering. As an IT Consultant for Centarus, Scott works with clients to provide troubleshooting & support. He recently sailed his first ocean crossing from Hawaii to San Francisco.
