Leadership That Moves the Mission Forward

Sowmya Hariharan
Sowmya Hariharan
President & CEO

I have proudly served as President and CEO of OM Group Inc. since July 2013, following a foundational ten-year tenure as Vice President. Under my leadership, the firm successfully pivoted from commercial markets to the federal IT space — a transition that drove rapid growth and success. Today, we specialize in delivering enterprise-level digital transformation for federal agencies.

An empty nester mom to 3 grown adults, I live in Edison, NJ with my husband of over 33 years.

In my spare time, I enjoy crafting and painting. I am also an avid reader and love to travel.

Chief Operating Officer

As the COO of OM Group, I oversee Business Development, Operations and Delivery. Prior to OM Group, I spent over 15 years in Product Development and Management as part of large commercial entities such as Motorola, Analog Devices, and BlackBerry. Pivoting my career to launch an IT services organization targeted to serve federal government agencies has been a phenomenally challenging, rewarding, and fulfilling experience.

I have a Masters degree in Engineering and Management from Massachusetts Institute of Technology, and a Masters in Electrical Engineering from University of Florida. Though I have stopped chasing degrees, I view myself as a lifelong learner. Fun fact – I learnt to swim at age 40! Having moved around a bit, I am now happy to call Northern VA home, and live in Great Falls with my husband, son and dog.

Theresa Webber
Sr. Director of Human Resources

I joined OM Group, Inc. in 2017 and serve as Senior Director of Human Resources. Over the years, I’ve had the opportunity to help shape not only how we grow as an organization, but also how we support the people who make that growth possible.

I work closely with our leadership team to ensure our people practices align with where the business is headed, while keeping the employee experience at the center of what we do. For me, HR is about more than policies and processes—it’s about building trust, creating opportunities, developing strong teams, and making thoughtful decisions that are right for both our people and the organization.

I’m passionate about creating a workplace where people know they are valued, understand how their work contributes to our success, and have the opportunity to grow with us. As OM Group continues to evolve, my focus remains on building the culture, leadership, and employee experience that will help carry us forward.

Voices from the Mission

The people closest to the mission see the impact of our work every day. Their words reflect the trust, reliability, and partnership we bring to every engagement.

Contractor provided very good management of the contract. OM Management was always available either on the phone or in person, whenever necessary. OM Management was outstanding in the manner in which they back-filled personnel who resigned for other employment opportunities. OM Management provided timely and proactive communication with the government team and the COR and is extremely vigilant when it pertains to making sure the customer is satisfied with the level of effort that is provided by the assigned contractor personnel.

DoD Customer

OM Group provided an extraordinary amount of time, energy, and technical expertise assisting in the development of the Cyber Security/ Risk Management Framework/ Information Assurance program for the U.S. Army Combat Readiness Center.

ISSO, USACRC

The contractor fully embraced the spirit of “continuous/continual improvement”. They did not wait to be tasked; instead, they regularly brought forward well-researched recommendations based on Lean methodologies that eliminated process waste and improved product delivery. Several of these recommendations were adopted, resulting in measurable cost and time savings for the government.

COR and Technical POC, USACE

OMGroup has been getting cloud migrations right for a long time. It has become an expectation for OMGroup to “get it right” whenever called upon. Again – thank you for supporting G-9!
