Head Coach
John Lavallee

Now into his second decade at UC Davis, John Lavallee wasted no time in establishing his mark on the Aggie women's gymnastics program.

In 11 seasons at the Aggie helm, he has earned Mountain Pacific Sports Federation Coach of the Year six times. Seventeen of his student-athletes have earned at-large berths to the NCAA region championships in his UC Davis tenure, with two -- Tanya Ho and Katie Yamamura -- garnering individual qualifiers in three different seasons. Lavallee has also guided his program to six MPSF team championships, including four straight from 2010 to 2013.

However, his crowing achievement with the Aggie women's gymnastics program came in 2014. That year, UC Davis set or tied team event records on all four events plus the total score of 196.425 at home against Seattle Pacific on February 28. In all, the Aggies scored seven of their all-time top 10 totals during that year, resulting in a school-record RQS of 195.260, a No. 34 national ranking and the program's first team berth to the NCAA postseason since 1998. UC Davis finished fifth at the NCAA Fayetteville Regional.

Lavallee's student-athletes have also performed in the classroom, winning four straight Marya Welch Awards (2009-12) for the highest women's team GPA at UC Davis. Additionally, Aggie women's gymnastics earned five consecutive NCAA Public Recognition Awards for Academic Progress Rate (2011-14) and 10 straight NACGWC/W Academic Team honors (2008-17).

In 2016, he enjoyed yet another milestone achievement, when Tanya Ho, a 13-time all-conference honoree, became the first Lavallee-era gymnast to enter the Cal Aggie Athletics Hall of Fame.

Before arriving at UC Davis, Lavallee enjoyed a successful three-year stint as the top assistant for longtime Yale mentor Barbara Tonry. In the past two seasons, he and Tonry guided six Bulldogs to at-large appearances at the NCAA Northeast Regional. Furthermore, Yale captured an Ivy League title in 2005.

Prior to his stop in New Haven, Lavallee spent 11 years as director and head coach of the Sterling Academy of Gymnastics in Sterling, Mass. In addition to his work with club's recreational programs, which grew to more than 1,000 students, Lavallee coached champions at the state, regional and national level, plus a member of the 2002 Junior Olympic National Team. He served as meet director at many levels including the 1999 USAG Eastern Championships. Also during his time at Sterling, Lavallee taught gymnastics as a physical education course at Atlantic Union College in Lancaster, Mass.

While at the Sterling Academy of Gymnastics, Lavallee earned three USAG Service Awards for his contributions to his sport and served as a member of the USAG State Administrative Committee as Massachusetts' Junior Olympic representative.

Lavallee was a collegiate gymnast at Springfield College in Springfield, Mass. In 1986, he earned U.S. Gymnastics Federation All-America honors on floor exercise and served as team captain. Lavallee earned his bachelor's degree in general studies in 1987, then returned for his master of education in 1992. While completing his master's work, he served as a graduate assistant for the Chiefs (now the Pride) and taught gymnastics classes in the physical education department.

Lavallee's wife, Teri, served on the Aggie gymnastics coaching staff as an assistant coach.

Assistant Coach
Carolyn Kampf

Former Aggie Carolyn Kampf enters her 10th year on the gymnastics coaching staff in 2018, now working primarly with the vault and floor squads. In both 2011 and 2013, her efforts were rewarded with MPSF Assistant Coach of the Year co-honors.

In 2014, Kampf's efforts helped the Aggies score four of their 10 highest vault team scores in school history, including a school-record 49.050 in a home quad meet on January 26. That served as one of many highlights in a landmark season that saw UC Davis amass a program-record RQS of 195.260 and earn its first team berth to the NCAA postseason since 1998.

A year later, Tiana Montell and Katy Nogaki each tied the individual UC Davis vault record of 9.900 twice each. Under Kampf's tutelage, the Aggies notched seven of the all-time top 10 vault scores in that 2015 season, including the record of 49.250 in a home dual with Washington on March 13, 2015.

Kampf's floor exercise squad also set a school record (49.450) in that dual with the Huskies. More recently, the Aggies hit such floor marks of 49.250 and 49.350 during the 2017 season, also among the program's top 10.

Originally from All-Olympians Gymnastics Center and Palisades Charter High in Los Angeles, Kampf lettered four years at UC Davis, competing primarily on bars and floor in her final two seasons. She enjoyed a career-best meet against Seattle Pacific on a senior, scoring personal highs of 9.775 on bars and 9.850 on floor in the meet.

Kampf, who graduated in 2007 with a psychology degree, also captured MPSF All-Academic honors as a junior and senior. She later earned an M.S. degree in counseling with a specialization in career counseling from Sacramento State in 2010.

In addition to her coaching duties, Kampf served as an academic skills specialist for the Aggie athletics department.

Assistant Coach
Jessa Hansen

Jessa Hansen, formerly a coach at California and Head Over Heels Athletics Arts, joined the UC Davis women's gymnastics staff in June 2016. She works primarily with the beam squad while also serving the role of recruiting coordinator.

In Hansen's first season, the Aggies set a school beam record with a 49.175 at home against Air Force, then reset the benchmark at 49.225 the following weekend at the MPSF Championships. Additionally, then-junior Alexis Brown tied the individual record of 9.900 three times that year before Katy Nogaki hit a new standard of 9.925 in her final collegiate meet.

Hansen served for three seasons as an assistant to Golden Bears head coach Justin Howell, working in all aspects of the Cal program, including recruiting and team promotions. During that time, the Golden Bears finished 16th, 18th and seventh nationally, culminating with last year's appearance at the NCAA Championships -- just the second in program history. She helped Alicia Asturias (2014) and Toni-Ann Williams (2015, 2016) to All-America honors, with Williams later becoming the first Cal gymnast to qualify for the Olympic Games.

Hansen also served as a coach for the Emeryville-based Head Over Heels club during her time at Cal. Working with athletes of Levels 3-10, she guided teams and individuals to Junior Olympic state, region and naional titles.

Originally from the Des Moines, Iowa area, Hansen attended the Univesity of Iowa, where she won two All-Big Ten Conference awards and three Academic All-Big Ten nods during her career from 2009 to 2013. She added NACGC/W Scholastic All-America honors from 2010-12, Big Ten Sportsmanship awards in 2010 and 2011, six total Dean's List appearances, plus a nomination for the 24 Hawkeyes To Watch list in 2012. After completing her degree in journalism & mass communication, Hansen served as both a volunteer assistant and sports information contact for women's gymnastics for the 2013 season.

Prior to her collegiate career, the Waukee Senior High School grad was a teammate with 2008 Olympic gold medalist Shawn Johnson at Chow's Gymnastics, the same club that later produced Team USA members Gabby Douglas and Rachel Gowey.

Volunteer Assistant Coach
Anna Shumaker

One of the top gymnasts in program history, Anna Shumaker returned to the program to serve as a volunteer assistant coach in 2019.

Originally from Alameda, California and Pacific West Gymnastics, Shumaker starred for the Aggies from 2011-14, during which she earned 12 All-MPSF honors and competed at three NCAA regionals. The exercise biology major culminated her career as a senior team captain, when she set a school and conference record for all-around RQS at 39.175, claimed four MPSF Gymnast of the Week awards, and made the all-conference rolls in all four categories plus the all-around. Shumaker was one of just two athletes (along with San Jose State's Cami Guyer) to earn the maximum five All-MPSF awards that year. She also scored 39 or better in the all-around six times in 2014, including a career-high 39.275 in the February 28 home dual with Seattle Pacific.

Perhaps more significantly, Shumaker led UC Davis to its first NCAA postseason team berth in almost two decades. The Aggies compiled a 195.260 RQS to claim the 34th of 36 regional spots. Individually, Shumaker finished in a tie for 12th on both vault and floor at the meet in Fayetteville, Arkansas. She had previously qualified for the NCAA regionals as an individual at-large competitor as a freshman (vault) and junior (all-around).

After concluding her collegiate gymnastics career, Shumaker entered a new competitive arena, eventually appearing on Team Ninja Warrior (2017), American Ninja Warrior: Ninja vs. Ninja (2018), and American Ninja Warrior (Seasons 9 and 10). She finished as the No. 2 female competitor at the 2018 Los Angeles finals, which aired on NBC that July. Shumaker serves as a personal trainer in Sacramento, and owns her own company, known as SHUFIT (

Retired Assistant Coach
Tamara Ross

After six seasons as an assistant on John Lavallee's women's gymnastics staff, Tamara Ross announced her retirement after the 2015 season -- ending more than 30 years of club and collegiate coaching. Fortunately, the lure of the gym could not pull her away completely: Ross returned to the program as a volunteer assistant in 2016.

A former Sacramento State assistant coach, Ross crossed the Yolo Causeway to join the Aggies as Lavallee's top assistant prior to the 2010 season. She served all aspects of the program, working primarily with balance beam in the gym. In 2012, her work in that particular area earned Ross a nod as the MPSF Assistant Coach of the Year. Two years later, during a historic season in which the Aggies earned their first NCAA team appearance since 1998 and compiled a school-record 195.260 RQS, Ross captured even higher honors: NACGC/W West Region Assistant Coach of the Year. The accolade was well-founded, as UC Davis posted six of its seven all-time best beam scores that year, including the school-record 49.175 on February 21.

Ross served eight years as a team choreographer for Hornet mentor Kim Hughes. She served from 1998-2001, then returned in 2004 to coach for four more years. Ross' guidance helped Stefanie Aeder set a school record on floor exercise and qualify for back-to-back NCAA West Regionals.

Between her tenures at the collegiate and club level, Ross brings a quarter-century of experience to the Aggies. As a club coach and a member of the NorCal Coaches Association, she earned Optional Coach of the Year in 1996 and Choreographer of the Year on three occasions (1994, 1995 and 1997).

In 2005, Ross was selected to coach the U.S. open women's gymnastics team at the Maccabi Games in Israel. Under her tutelage, the American squad posted a second-place finish and had individuals finish second on floor and beam.

More locally, Ross served on the Sacramento Sports Commission local organizing committee, helping bring the 1999 John Hancock U.S. Gymnastics Championships to Sacramento.

A 1971 graduate of San Diego State, Ross later earned her master's degree from Sacramento State. She and her husband Arthur have two sons, Brian and Greg.
