Tiffany D. Kellner, CFP®, CDFA®, CPWA®

Senior Vice President–Wealth Management

Financial Advisor

Tiffany knows that when it comes to discovering what is important to people, nothing is more powerful than having great listening skills.  While it’s essential to also have the knowledge and resources for financial planning, building trust comes from active listening.

Having lost her father when she was young, she learned what can happen to a family without the right plans in place.  From these struggles grew a passion for helping her clients reach their goals, but also a strong focus on helping protect them from life’s uncertainties.

Tiffany believes her best work is done with individuals or families for whom she can make a significant impact – those that are looking for a financial partner they can trust to provide solutions for some of their most important decisions.  

Tiffany has been in the financial industry for 25 years, starting her career while still in college, majoring in personal financial planning. She currently serves on the Board of Directors for the Gala of Hope Foundation and is a member of the UBS PAC. She and Eric reside in Centerville with their clever and loving children, Evan, Emelia and Adalyn.

Blair T. Cornell, CFP®, CPWA®


Managing Director–Wealth Management

Private Wealth Advisor

Financial Advisor

Blair knows he is at his best when he is challenged to think outside of the box to help a client reduce their concerns and, ideally, find opportunities they may not have thought possible. 

Having worked with his father his entire career, he learned the importance of patience and authenticity in working alongside clients. And, like his father, Blair believes that building trust is more valuable than any product or strategy.

Today, as a Private Wealth Advisor, he specializes in strategic planning for high-net worth clients.

Blair and his wife are the founders of JoyRide, the non-profit that brings together special needs kids and car enthusiasts. Inspired by their son, JoyRide allows kids to trade the everyday worry of doctor’s visits and medications for a chance to cruise in high-end or one-of-a-kind cars. A disciplined philanthropist and entrepreneur, Blair often speaks to groups about his journey with JoyRide and the fulfillment of combining your passions.

Blair is a native of Kettering and resides in Centerville with Kat and their children Caitlin, Carter and twins, Brady and Davis. He enjoys golfing, spending time in the mountains of Colorado and boating with his family.  Blair has been an active member of Fairhaven Church for over 30 years.

Colin C. Faulkner, CFP®

Senior Wealth Strategy Associate

Colin believes this work is in his blood, as evidenced by the framed notepad hanging in his home office that his grandfather used to track stocks on during church services.

Over the last few years, Colin has come to know there is no such thing as a typical financial plan. He places emphasis on understanding client’s goals so he can identify any roadblocks to their success

Equally important to his work, Colin values his network of fellow advisors and professionals that help with issues beyond investing.  He knows that if he does not have an answer, he certainly has powerful resources to tap.

While not building financial plans for clients, Colin spends time with family and friends, reading, improving his health and fitness as well as finding opportunities to serve in the local community and his church.
