Diane Sullenberger


Diane Sullenberger has been a PCA Potomac Club member since 2009 and has greatly enjoyed getting to know club members, volunteers, and drivers from other regions and clubs and as DE Co-Registrar since 2018. She has volunteered at the PCA Potomac Club Race since 2015 as a flagger and then as pace car communicator, and often can be seen helping out on grid tech at DEs.

She didn’t realize she had a passion for motorsports until 2000 when she took her Honda S2000 to Friday at the Track (FATT) at Summit Main. After three events and one agricultural excursion in Turn 3, she was advised by her insurance not to track her car again, so she bought a Ducati motorcycle (2008 848) and soon began tracking it, then racing it with WERA. Owning her first Porsche (2006 C2S, then 2011 GTS) introduced her to a wealth of new opportunities to learn about the Porsche driving and racing history and to getting to know a diverse group of people at weekend driving events at meet-ups, social events, in the paddock at race tracks, and more. She welcomes the opportunity to serve the club more broadly as Vice President and ensuring that the hard work and collective action of the many-faceted committees and volunteers of PCA Potomac continue to benefit from decisive and effective club leadership.

She has lived in the DC Metro area almost all her life and is executive editor of the research journal of the National Academy of Sciences. Her husband, Scott Antonides, drives his 2004 BMW 330i ZHP with the BMW Club and FATT, and often attends PCA social events. When Diane is not at the track, she competes at National Cutting Horse Association shows on her quarter horse, Magic Lights, and teaches her border collie, Marvel, new tricks.



Stephen Kiraly


Stephen Kiraly has been a member of Potomac PCA since 2012, when he purchased his first Porsche, a 2006 997 Cabriolet. Once he discovered PCA, he and his wife, Debra, became involved in the many Potomac events that give our Club such a good name.

Stephen got his start with Porsches after a stint riding high performance motorcycles. After deciding four wheels really are better than two, he began his “search” for the perfect car. If he only knew then what he knows now

After many months of searching for the car that would meet all his goals, which at that time were limited to color, convertible top and coolness, he found his car at a Lamborghini dealer in Atlanta. Confident is his decision he bought a one-way ticket to Atlanta. When the Dealer pulled up in car at the airport, he knew he wouldn’t be buying a return ticket. Three hours later he was on his way home in his 1st Porsche.

Learning of Potomac upon joining PCA, Stephen signed up for the Fall HPDC formally starting his journey down the “slippery slope” of Porsche high performance driving. After an off-track excursion at the very next DE, Debra said he couldn’t take that nice car to track again. Not to be deterred, Stephen purchased an inexpensive, at least in terms of Porsche Bucks, 2002 Boxster S just in time for the next Potomac DE. In fact, he drove his new purchase directly to the track and was “black flagged” for a loose 30-day tag.

In the following years, Stephen has continued his slippery slide purchasing a 2009 Cayman S track car along with an enclosed trailer and a new pickup truck to pull it. Stephen became a DE instructor in 2016 and enjoys giving back in the way that all the great instructors he had gave to him. He also became an official steward for the DE program in 2016. The 2020 Club Race at Summit Point will be his debut to PCA Club Racing.

Stephen and Debra have also enjoyed the social activities that Potomac organizes. He has been to Wintergreen, Homestead and Nemacolin “Drive and Stay” events enjoying the camaraderie of other Porsche enthusiasts, even if one of them drove a Corvette. Because as the say - It’s about the people…not just the cars.

Stephen has served two years as Potomac’s Treasurer and is committed to making the Club function as smoothly as possible in a sound fiscal manner.



Steve Bobbitt


Steve Bobbitt joined PCA in 2014 after purchasing his first Porsche, a 5-speed Meteor Grey Metallic 2008 Cayman, and immediately participated in the Autocross School and High-Performance Driving Clinic. Since then, he has continued to participate in Autocross and DE events, becoming a Nationally Certified HPDE Instructor in 2018 and serving as Autocross Chair in 2019 and 2020. Steve has also volunteered at Potomac's Club Race as the Steward's Assistant since 2017. After participating in over 30 PCA Potomac activities in 2019, he took home the coveted Enthusiast of the Year award at the annual awards banquet in 2020.

Steve's passion for PCA and these amazing vehicles started at an early age when he first laid eyes on his uncle’s 911 and heard about the club. Over the years, his cousins, father, and brother all acquired their own Porsches (914-6, 944 S2, 993 C2S, '87 911). After graduating college and starting a career in IT, it was time for Steve to get his own and join the club.

When Steve isn't preparing his 2009 Cayman S for the next DE event or helping fellow club members work on their cars, he enjoys hiking, yoga, and playing board games with his friends.



Gary Baker


Gary Baker was born in Stuttgart, Germany, home of Porsche, and spent his first 16 years there. As a child he enjoyed watching Porsches pass through his hometown dreaming that some-day he would own one. That dream came true with his first Porsche 928. He owned it for many decades before selling it to an avid Porsche enthusiast in Florida in 2018. Gary has also owned a 996, a Cayenne and currently owns a 991.

Gary first joined PCA in 2008 as a member of the Potomac, The Founders’ Region, and is currently Vice President. Over the past 12 years, he has served as Secretary, Autocross Chair, Club Race Chair, and became a PCA National High Performance Driver Education (DE) Instructor in 2013.

You will find multiple division titles and championships for the PCA Autocross program in Gary’s name. His enthusiasm for PCA events makes it easy for him to recruit new PCA members, another thing he loves to do.

Gary developed ways to improve the PCA experience for all members, including playing an instrumental role in creating the very first DE Instructor Candidate Program. He also designed numerous challenging driving exercises for the High Performance Drivers’ Clinics, and loves working with those brand new to high performance driving. You may have seen Gary’s name before as a frequent contributor to our very own der Vorgänger magazine on many topics concerning high performance driving, club activities and Porsche in general.

When not at work as a Travel Consultant, traveling or on the autocross course or racetrack, Gary enjoys water skiing, sky diving, go-karting, snowboarding, mountain biking and spending time with his co-driver and fiancé, Tessa Hall.



Mia Walsh


Mia Potthast Walsh has been in the Porsche Club since 2008, along with her husband, Brian. During this time, she has served as the Social Chair, the Membership Chair, the Volunteer Coordinator for the Potomac Club Race, Secretary from 2015-2016, Vice President from 2017-2018 and President from 2019-2020. She has enjoyed her leadership role in this amazing organization and looks forward to her additional two years as Past President in 2021-2022, while continuing to provide guidance to the Executive Board, especially during this turbulent time in our world.

Her passion in PCA Potomac is participating in the Drivers’ Education and Club Racing events, both as DE driver and a racer in GTB1 class, winning the 2015 Rookie Racer award by PCA National at Potomac’s Club Race, as well as three podiums over the years. She has been instructing for High Performance Drivers’ Education since 2013 and utilizes her communication and training skills honed as a high school teacher while in the right seat with Potomac’s novice drivers. Most of all, she enjoys the “romantic” weekends at the track, especially when watching her husband drive past her on the circuit in his always-newer-and-larger-horse-powered car.

In addition to HPDE, Mia enjoys taking her girlfriends to Rally and Drive & Dine events and was excited to participate (as a spectator) in her first real Concours in 2020; though she did once take home “Porsche with the Most Dead Bugs and Dirt” at the annual picnic’s Concours in 2018. She has been banned from Autocross after causing the death toll of orange cones to rise exponentially.

Mia is a frequent contributor to Potomac’s der Vorgänger magazine as both a writer and a photographer and has accumulated 8 DV covers since 2011, along with countless inside edition photographs. She is still waiting for Vranko and Chris M. to give her a PowerPoint deck so she can learn all the 911 model types by year and body style.

Mia’s favorite part of being part of PCA is talking to all the members about their love of driving Porsches. We each have a specific individual reason why we joined Potomac, but we all share the same passion of our fine German cars, however we may choose to drive them!
