Maumee, OH , - William Vaughan Company, certified public accountants and business consultants, and TDC Companies, a coordinated family of financial services firms, have announced a new partnership in which two CPAs from William Vaughan have become affiliated with TDC.

As an extension of William Vaughan's tax practice, David Hammack, CPA/PFS, and Aaron Swiggum, CPA/PFS, CFE, have become investment advisors working with TDC's investment firm. The new relationship benefits clients of William Vaughan because integrating tax and investment planning functions is a growing trend in the wealth management industry.

"For a number of years, William Vaughan has contemplated integrating investment advisory services into our tax planning specialty," says David Hammack. "We have searched far and wide for what we believe to be the right investment answer for our clients and feel we have found that in TDC Investment Advisory Services. We wholeheartedly embrace the investment philosophy TDC has utilized for over 20 years and believe our clients stand to benefit from the systems and processes they have built along the way."

TDC Companies agrees. "We believe integrating the investment advisory and CPA teams offers clients improved planning, communication and strategic direction," said Cleves Delp, Chairman, CEO of TDC Companies. "We are honored to partner with a quality firm such as William Vaughan whom we have admired for their unwavering commitment to client service for quite some time. While we have partnered with others around the country, this is the first such alliance for TDC in Northwest Ohio."

Hammack, of Maumee, and Swiggum, of Adrian, will operate within the new venture known as WVC Wealth Advisors.

Both TDC Companies and William Vaughan Company were both named a Top Workplace for 2013 by the Toledo Blade.
