Lee Ann Keller
LEAN STRATEGIC PLANNING | QUALITY | CAPACITY BUILDING | DEI
I am the president and chief executive officer of Omni Tech. Educated in mechanical engineering and business, I am also the chief strategist. I run the company, manage client relationships and specialize in Strategic Planning, Quality Management, Capacity Building and DEI (Diversity, Equity & Inclusion). I am a problem solver by nature and apply my creativity and technical expertise to help clients make a difference in their world. I like working on a number of diverse projects at one time.
As a born and bred “Yooper” (someone from the Upper Peninsula of Michigan), I am an avid outdoor adventurer and love to travel. When I’m not working, I’m usually doing something artsy, or trying to cook something complicated! You can often find me biking or hiking through northern MI or playing fetch with our fur babies Rocco and Sasha.

Ann Fillmore
LEAN STRATEGIC PLANNING | QUALITY | CAPACITY BUILDING | DEI
I am the senior non-profit advisor and a consultant for Omni Tech. My role is to position non-profits for long-term success by assisting them in all aspects of business development and management. To my role, I bring 25 years of executive non-profit experience including executing a $5 million annual community campaign. I truly believe relationships are the cornerstone to success which is why I enjoy working at Omni Tech. We make it a point to develop a trusted relationship with each client so we can help them reach their goals.
Outside of work, I enjoy spending time with my high school sweetheart who I’ve been married to for many years and spoiling my two amazing grandsons.

Bre Sklar
LEAN STRATEGIC PLANNING | QUALITY | CAPACITY BUILDING | DEI
I am the Project Manager and Strategic Planning Consultant of OmniTech International. I have an education in Accounting and Business Management and have been able to focus my expertise in the small business, corporate, non-profit, and government sectors. I have strong relationship building skills with a decade of experience with project management, strategic business planning, and data analytics. I am passionate about creating and integrating changes that enforce efficiencies, accountability, and continuity.
As a military veteran and an advocate for community collaboration I love to act as a servant leader. In my spare time I love to think of different ways to create inclusive environments and how we can move the needle on social change as a collective body. I bring my two young daughters everywhere with me. We love to volunteer, explore nature, experience the arts, and try new things together.
