"To Make our Clients Happy By Exceeding their Expectations"


Luhn-McCain Insurance Agency, Ltd.
Luhn-McCain Insurance Agency, was founded in 1984 by Marietta McCain, CIC and George M. Luhn, Jr. and was facilitated by the purchase of Dunlap Insurance Agency, Inc. of which Marietta McCain was Vice President and co-owner. Marietta purchased Mr. Luhn’s ownership in the agency in 2004 and became the sole owner of Luhn-McCain.
The Agency’s business mix was 70% Commercial, 15% Personal lines and 15% Benefits. The staff consisted of 2 producers and 10 support staff. All of the account managers are licensed and have professional ACSR and/or CIC designations and have been with the agency over 7 years. Luhn-McCain has a niche for writing social service organizations, although many other industry types such as manufacturers and contractors make up the $18 million dollar premium volume.

The Bank of San Antonio
A group of local business and community leaders envisioned a strong local bank committed to personal relationships and customer services that would be able to offer the products and technologies of a big national bank. In 2007, The Bank of San Antonio opened its doors to serve San Antonio Businesses. In 2012 the bank hired Michael Grossman, a million dollar seasoned benefits producer and Katy Brooks, CIC and Risk Manager as well as a 30+ year seasoned commercial producer with a $7M book of business both from BBVA Compass (formerly Texas Insurance) to open and run The Bank of San Antonio Insurance Group. Michael currently serves as the President and Katy as the Senior VP of the Insurance Division.

Luhn-McCain, A division of The Bank of San Antonio Insurance Group
In 2012 Mrs. McCain began looking for perpetuation opportunities and hired a consulting firm to help in the process. In the meantime, The Bank of San Antonio Insurance Group was struggling with insurance markets to place the large amount of business opportunities they were getting from Bank referrals. Katy Brooks contacted Marietta McCain to see if there was an opportunity to partner using Luhn-McCain’s markets and discussions soon began that ended in the merger of the two agencies effective July 1, 2013.

The combined agency is The Bank of San Antonio Insurance Group, Inc. DBA: Luhn-McCain, where the focus remains the same…to help businesses and individuals solve their insurance challenges. Michael, Katy and their staff joined Luhn-McCain at their location on Sunset Road. The combined strengths of Luhn-McCain’s reputation and long term staff with the relationships and resources that the Bank of San Antonio and the Insurance Group’s staff provides is already proving to be a grand success.
