For nearly a decade, the surname Kaltenbacher, while commonplace at The Classical Academy, has deeply rooted itself in the annals of Air Academy tennis.
First came Kyle (TCA class of 2007), followed by Kateri (2010). Most recently, Kollen (2013) departed the Kadets' tennis program.
Now, the last of the family foursome, Keenan, can look over his shoulder and know he's flying solo for a change.
"I kind of enjoy being the youngest," Kaltenbacher said. "It would be nice to have a younger sibling, though. I don't know if I have my own identity. I'm always someone's brother. My teachers ask me if there are any more of us."
Because TCA doesn't offer tennis, all four Kaltenbachers have played for Air Academy, another District 20 school that offers the sport.
Kaltenbacher, a junior at The Classical Academy, lost in the No. 3 singles championship match last fall to the now-graduated Andrew Venner of Cheyenne Mountain. One year later, the Kadets are counting on their soft-spoken returning letter-winner to lead the team.
In addition, Kaltenbacher has been slotted into the No. 1 singles position, a spot Kollen held last season.
"Being a leader is a new thing I'll have to pick up," Kaltenbacher said. "We only have two varsity returning players, so it's going to be a lot different this year. I'm going to have to step it up and lead our team, and that's going to be different."
Kaltenbacher and the Kadets also will have to adjust to a coaching change. Longtime mentor Ron Gorr resigned after 11 years. Matt Kiser, who taught lessons to many of the Kadets years ago, was chosen to lead the program.
"It's going to be a lot different this year," Kaltenbacher said. "There are a lot of new people and a new coach. I think it'll be a good year for us."
Part of the Kadets' success hinges upon the further development of Kaltenbacher at No. 1 singles. He hopes to parlay a three-set loss to Venner last year into a positive as he enters a new frontier - not only as a tennis player, but also as the last of his family to make a name for himself.
He'll still have company, though. Kollen is attending Colorado-Colorado Springs this fall and reportedly has plans on attending Air Academy practices and matches.
That's assuring to the last Kaltenbacher.
"It'll be nice to have him around," Kaltenbacher said. "I won't miss the arguing and fighting that happens when you're brothers, but I will kind of miss him being there for me. This year, I'm pretty much the same guy, but I just have to be more confident in myself."
Coach: Jason Smits
Key players: Noah Jones, jr.; Eli Peterson, sr.
Season outlook: Eight returning letter-winners give Smits a solid foundation for his first year as a Spartan after five seasons at Mitchell. Additional depth will be provided by junior Daniel Slaugh and seniors Mitchell Palmer and Andrew Johnston
Coach: Joe Frasca
Key returners: Matt Jacobberger, sr.; Alex Chang, sr.; Cody Leasure, sr.; Tyler Leasure, sr.; Sam Sommers, jr.
Season outlook: The Lancers return five letter-winners from last year's 5A CSML champions and sent a singles player to the 5A state tournament for the second straight season. As a sophomore, Jacobberger finished runner-up at regionals to qualify for state, and the now-graduated Nate Miller won the region last year, a Liberty first. Leasure was part of the No. 2 doubles team to reach state in 2012 as well.
Coach: Todd Nelson
Key returners: Asher MacEnulty, sr.; Weiliang Sun, sr.; Jacob Briggs, jr.; Drew Dickey, so.
Season outlook: Nelson has a solid nucleus in place with seven players with varsity experience returning for the 2013 season. Last season, the Terrors won five of eight duals.
Coach: Dave Lehman
Key returners: Zach Inman, sr.
Season outlook: Last season, Inman was one of just two singles players in the Colorado Springs area to qualify for the 5A state tournament. This season, he's one of only two seniors on an Eagles team that has plenty of fresh faces. Still, the 2012 Metro League runner-up should contend once again.
Coaches: Laura Kellar and Brian Kimsey
Key returners: None.
Season outlook: At press time, an inexperienced Rams' varsity roster still wasn't set.
No report: Fountain-Fort Carson
Coach: Matt Kiser
Key returners: Keenan Kaltenbacher, sr.
Season outlook: Kiser, in his first year after previous coach Ron Gorr stepped down, inherits a team that lost eight seniors but has plenty of underclassmen ready to step up. Kaltenbacher reached the No. 3 singles state final last season but fell to now-graduated Andrew Venner of Cheyenne Mountain. Kaltenbacher will move up to No. 1 singles for his junior season.
Coach: Dave Adams
Key returners: Austin Hampton, sr.; Will Geisz, sr.; Robbie Boe, so.; Colt Sessions, sr.
Season outlook: The beat went on last season when the Indians claimed their third consecutive team championship and 17th overall. The 2013 version will look different with just four returning letter-winners, but the cupboard is far from empty. Hampton won state at No. 1 doubles after doing the same at No. 4 doubles in 2012. Geisz and Boe finished third at No. 4 doubles at state last season, while Sessions, the two-time 4A state high jump champion, started his school year by winning the title at No. 3 doubles.
Colorado Springs Christian School
Coach: Troy Rahner
Key returners: Jeremiah Hanson, so.; Jarod Adducci, so.; Brandon Russell, so.; Won Back, sr.; Ryan Troester, so.
Season outlook: The future is now for the Lions, whose returning nucleus is dominated by sophomores. Hanson spent his summer competing in regional tournaments and is expected to compete for a 4A state berth. Adducci was last season's team Most Valuable Player, while Troester won the Newcomer of the Year award.
Coach: Mike Humphrey
Key returners: Luke Lorenz, sr.; Baylor May, so.; Robert Olson, sr.
Season outlook: The Thunder bring back nine varsity returners, highlighted by Lorenz, a three-year letter-winner who finished fourth at last season's 4A state tournament. In addition, May qualified for state at No. 3 singles, and Olson returns to give Discovery Canyon experience at No. 1 doubles.
Coach: Randy Jones
Key returners: Doug Adams, sr.; Kyohei Takiya, jr.; Fermin Serrano, jr.; Zack Salama, jr.; Phil Fan, jr.; James Gu, sr.; Sasith Weerasundara, jr.
Season outlook: The Danes are blessed with experience, led by Adams and Takiya, their top two singles players from last season. Serrano, Salama, Fan and Gu all qualified for the 4A state tournament in doubles in 2012.
Coach: Paul Kardel
Key returners: Jared Stuart, sr.; Thomas Gregory, sr.; JK Balk, sr.; David Meleski, sr.; Kyle Flynn, jr.; Nick Sherman, sr.
Season outlook: Stuart leads an experienced group of Rangers, returning to play No. 1 singles, while Gregory is slotted at No. 3. Balk leads four returning-letter winners who played doubles last season.
Coach: Lisa Felice
Key returners: Jason Tafoya, jr.; Ben Ryberg, sr.
Season outlook: Felice expects big things from Tafoya this season, with all the tools to compete at No. 1 singles in a talented region. Ryberg brings senior leadership and a great attitude to the Grizzlies.
Coach: Mikael Peterson
Key returners: None.
Season outlook: Peterson recently took over as Marauders head coach and, as of press time, had not finalized what should turn out to be a young and experienced roster after a senior-laden squad in 2012.
Coach: Dale Kahre
Key returners: None
Season outlook: After a long tenure at Widefield, Kahre starts anew at Sand Creek.
Coach: Dina Fuqua
Key returners: Joseph Adducci, jr.
Season outlook: Adducci finished runner-up at last season's Region 6 tournament at No. 1 singles to qualify for the state tournament.
Coach: Chad Anderson
Key returners: Dominique Warren, sr.
Season outlook: Warren is the lone returning upperclassmen for the Gladiators. Meanwhile, freshman Marcos Salazar could make an impact right away.
