Bob Tunnell - President & General Manager

Bob manages the day-to-day business operations of the Bimmer Haus Performance Group (Bimmer Haus and Apex Hyperformance) and serves as a consultant on all racecar prep and development.

Bob's first foray into professional motorsports was as General Manager of Seattle International Raceway in the early 1980's overseeing all facility operations and promoting NHRA and AMA events.

He continued to promote Indy Car, IMSA, and NASCAR races in the Seattle and Portland markets before joining Warren Miller Films as Associate Producer on 10 feature-length films and Executive Producer of more than 50 nationally syndicated television shows (including 5 about auto racing). Bob also served as General Manager of Warren Miller Entertainment overseeing all day-to-day operations prior to the company's acquisition by Times-Mirror Magazines and ultimately AOL.

Over the years Bob has performed stunt and high-performance driving sequences for feature films and television shows and appeared in several national and regional television and newspaper automotive ad campaigns. He has also taught high performance driving, vehicle evaluation, and corporate motivational programs for nearly a dozen European, Asian, and North American automotive manufacturers.

As a competitor, Bob has won 12 Solo II and ProSolo National Championships. (His wife, Patty, has also won 17 National Championships!) He is a graduate of the Jim Russell and SCCA Competition Driving Schools and holds numerous road racing track records in Showroom Stock and Touring class cars.

Bob also serves on the Board of Directors of Sozo International, a humanitarian aid NGO serving critically poor and disadvantaged people in Afghanistan. In recent years Bob has made 21 trips to Afghanistan to provide emergency aid and long term developmental support in a refugee camp called Barek Aub north of Kabul. Bob's wife, Patty, is also involved in the work in Barek Aub and has traveled there eight times with him. They both have plans to go back again in 2016.

In his spare time (those rare weekends not spent racing or traveling) Bob enjoys outdoor activities like golf, scuba diving, golf, heli-skiing, more golf, and hiking with Patty. And then maybe a little more golf.

Although he denies being a "collector," Bob currently owns ten BMWs: a 1995 M3, 2001 740iL (daily driver), 1996 740iL, 1995 525i, 2005 325Xi, another 2005 325Xi, yet another 2005 325Xi, a 2003 330Xi, a 1994 325i, a 2003 M3, and has built the 1995 M3 into an E-Modified autocrossing monster into which the guys have dropped an LS3 V8. In the past he has also owned a 2002 M3, a 1994 325i, 1994 325is, 1997 M3 sedan, 1998 328iC, 1991 318is, two 1989 325ix's, a 2002 330i, a 1988 525i, and a 1990 M3.

Jim Leithauser -- Senior Technician and Race Car Fabricator

Jim serves as our Chief Technician performing general service and repairs, and also oversees all of our high performance projects and race car fabrication and prep work.

After majoring in Mechanical Engineering at the University of Kentucky, Jim began his automotive career at an independent BMW/Porsche/Audi repair facility more than 25 years ago. Certified as an ASE Master Technician, Jim soon opened a repair and restoration facility of his own specializing in BMW and Porsche automobiles.

He was recruited in the early 90's to become the new Technical Manager for the SCCA'S Club Racing program where he helped develop the rules package for the conversion of Showroom Stock racing to the current Touring rules structure.

Jim left the SCCA in early 2000 to take over as Sales Manager for the joint venture startup between TC Kline Racing and Tri-Point Engineering, ProPartsUSA. He also served as Manager of the Koni Rebuild Center, one of only three factory authorized Koni shock and strut rebuild centers in the country.

Jim's competitive career began in the mid 70's where he won 9 trophies at the Solo II and ProSolo National Championships, but he had to put driving on hold when he went to work for the SCCA in 1993. But he didn't have to put his vehicle development skills on hold and he continued to design and prepare winning race cars culminating in Bob Endicott's win -- in Jim's ITA car -- at the American Road Race of Champions at Road Atlanta in 1999.

Since leaving the SCCA Jim has continued his racing career and won the SSB National Points Championship in the SCCA'S Rocky Mountain Division in 2001, 2002, and 2003 as well as winning a Club Racing National Championship at the 2004 SCCA Runoffs in SSB in a BMW Z4.

When asked what he likes to do in his spare time, Jim replied: "Work!" ....(I guess it beats getting trounced by his daughter at the go-kart track. <g>)

Jim's daily driver is a gorgeous 2007 Z4 3.0 Coupe and he also currently owns another Z4 3.0 Coupe that he's built into a competitive T3 racecar. In the past his stable held a 1988 325ix, 1998 Z3, 1999 M3, 1998 M3 sedan, and a gorgeous 2003 Z4 2.5 that he built into that National Championship-winning track racer.

Pat Pallotto - Service Manager & Bimmer Haus Baseball Team Captain

Pat is no longer the newest member of the Bimmer Haus crew... but he's just so darn much fun to heckle we're gonna let the "freshman hazing" go on for a while longer.

Pat is the voice that greets you on the phone and the smiling face at the front desk whenver he's not sweeping, taking out the trash, processing invoices, fixing our lunch, shining our shoes, or doing any of the other 1,324 duties we've put on his job description. But Pat was a member of the National Honor Society in college so I'm sure he's smart enough to get it all done.

Speaking of college, Pat was also the starting pitcher on their baseball team, but please don't tell the Rockies because he could probably make their starting rotation and I don't want to lose him!

Automotively his daily driver is a really sweet, super clean 2008 MazdaSpeed 3 and 2004 Yamaha R6 sport bike. He says he's always wanted an E30 M3. (And he told us that after he got the job, so I don't think he was just suckin' up.) He also loves classic cars and says on weekends you can probably find him at a local car show.

In his spare time Pat volunteers with a local fire department, coaches a Little League baseball team, and delivers meals to the elderly. He's a really sharp guy and -- despite the fact that he's making the rest of us look bad -- we're lucky to have him as part of the Bimmer Haus team!

Patty Tunnell - Front Desk, Bookkeeper, Controller, a.k.a. "SWMBO"

Patty has been co-owner with husband, Bob, since Bimmer Haus opened its doors in 2001. Until recently she has remained behind the scenes quietly handling marketing and customer satisfaction duties in her spare time while managing a successful dental practice in Boulder. When her former boss retired, Patty began filling in at the BHP front desk a couple days a week while Pat was taking classes.

Although Patty is a new face to the Bimmer Haus office, she is no stranger to the motorsports world. Patty is a 17-time National Champion in SCCA Solo and ProSolo competition and has been awarded the prestigious SCCA Solo Driver of Eminence and Spirit of the Sport Awards and is the only driver, male or female, in SCCA Solo history to win National Championships in 5 different racing categories.

For the record, I taught Patty how to drive when she was 15 so she couldn't have done it without me! (That's my story and I'm sticking to it. ;)

Seriously... Patty brings a lifetime of experience not only in motorsports but also in the business world having achieved success as one of the nation's top skip tracer/collectors for a major Fortune 500 company and coordinated world-wide travel and film and television distribution for a top independent filmmaker.

In recent years Patty has made 10 trips to Afghanistan with husband Bob to provide emergency aid and long term developmental support in a refugee camp called Barek Aub north of Kabul and has plans to go back again in 2018. She also actively serves at Flatirons Church and supports several local non-profit organizations.

In those rare moments when not working, racing, or traveling, Patty is a highly competitive racquetball player. She will tell you that she's not "competitive," but the guys at the racquet club will tell you otherwise. She also enjoys hiking in the foothills all around Boulder with her girlfriends.

Patty brings a new level of customer service to the BHP front desk with a smile and spiritied attitude that's second to none. (Yes, I'm biased... but it's still true.)
