Kevin Prendergast

CFP®, CFA / Partner

I’ve helped hundreds of AT&T employees prepare for and transition into retirement. My unique ability is to translate complex financial concepts into plain English. For that reason, you’ll find me featured in our educational content across all channels including our website, social media, and live events.

Chris Dieckow

CFA®, CFP®, CWS® / Wealth Advisor

Working together 1-on-1, I will help you make some of the highest impact, most consequential decisions of your financial life surrounding retirement from AT&T. How and when to start your Pension. Medical coverage in retirement. Identifying the most effective and tax-efficient sources of retirement income. Developing a customized investment plan. I take my commitment to you and your family seriously, which is why I’ve surrounded myself with the exceptional team at The Retirement Network after more than a decade with Charles Schwab. And I’ve gone above and beyond to educate myself – achieving the CFA® designation, which is often regarded as the gold standard in our profession.

I’ve guided AT&T employees to and through retirement for more than 20 years. Drawing from my experience, I can often answer questions the Benefits Center cannot.

Brian Dorn

AIF® / Chief Investment Officer

Many of you own AT&T Shares within your 401(k) and elsewhere, so I monitor AT&T from the perspective of an investor. I can help you determine if you should buy, sell, or hold your AT&T Shares. After you retire from AT&T, I help you and your advisor design and manage a personalized investment portfolio.
