Built on relationships.
Grounded in trust.

Insurance is built on details, but lasting partnerships are built on trust. At OGA, we bring together market access, experienced support, and a relationship-first approach to help independent agents serve their clients well.

OGA has been serving independent agents for over 70 years—and while a lot has changed since 1951, our foundation has remained the same. We’ve grown from a small Oklahoma City operation into a Managing General Agency and Surplus Lines Broker with expanded market access and carrier partnerships across the region, guided by one principle: transactions are temporary, trust is timeless. We’re family-owned, locally operated, and committed to the agents who’ve trusted us with their business for decades.

Our Values

Be Exceptional

We hold ourselves to a higher standard in every interaction — from finding the right market to navigating complex challenges. We take pride in our work, stay engaged from start to finish, and continually strive to raise the bar.

Lead with Integrity

Doing what’s right is our standard. It shapes how we evaluate risks, how we communicate, and how we support our agents and our team. Even when decisions are complex, we choose clarity over convenience and responsibility over ease.

People First

At the heart of everything we do are the people we serve. We approach every partnership with attentiveness and genuine investment in our agents’ success. Loyalty, respect, and gratitude guide our work – because when our agents succeed, we all do.

1951

Building A Legacy

On a scorching summer day in Oklahoma City, Marie Welch founded OGA at her kitchen table, determined to solve a gap in the market. At the time, rural insurance agents were often overlooked by big carriers and had limited products to offer. Marie saw an opportunity to support these independent agents — and she took it. What began in a small building next to the now-famous Kaiser Ice Cream shop quickly grew into a company fueled by purpose, grit, and a pioneering spirit.

1988

A new chapter begins

As Oklahoma navigated the economic turbulence of the 1980s, OGA held steady. In 1988, leadership passed to one of the agency’s rising stars — Baron Garcia. With deep respect for the company’s legacy, Baron continued to operate OGA as a family business, maintaining its strong foundation while adding a bold marketing and acquisition strategy. Under his direction, the company grew to over $25 million in sales, welcoming new carrier partnerships and expanding its reach across the state.

PRESENT

Built to last

75 years later, OGA remains family-led under Jenny Dotter’s leadership and is still rooted in the same mission: supporting agents through service, relationships, and market access built around their needs. We’ve weathered industry changes, economic cycles, and shifting regulations, but the foundation hasn’t changed. When you partner with OGA, you’re working with a team that’s been refining this craft since 1951. Same values. Stronger partnerships. Better solutions.

Words from our partners

What makes OGA stand out is the personal relationships with the staff. Everyone cares about giving good customer service and the staff are caring and involved in the process to obtain quality insurance for our insureds.

Berrong Insurance Agency

With OGA, I really feel like they are here for the agency and the insured. Everyone I have worked with is so very willing to listen and to help with anything and everything that they possibly can to get the job completed. And to top if off, they most always come up with a win-win; for the insured and the agency.

ECI Insurance Agency

OGA has always been amazing. When I started in the business of insurance, I really didn’t know anything about it.

They were always quick to answer the call or email and help me with any quote, policy or question that I had. They still help me out daily. Even with my most basic or odd of questions and they never sound bothered. OGA is the one and only, go to place for a broker with a personal touch.
