2022 Board Members



Glenda McElroy

Chapter Chair

Glenda has been a member of LA Chapter Board for a number of years. She owns Glenroys Equestrian Gifts and Cornerstone Event Management. She organizes LA Chapter Shows and manages the year end award program for the chapter.

Anna Armstrong

Anna started riding at 6 years old in her hometown of San Diego, discovered dressage at 14, and fell in love with the feeling of connection with the horse.  She rode horses of all types and talents belonging to friends, and got her first horse at 18, a crazy off-the-track Thoroughbred for $400.  The mare eventually calmed down and made it to second level, followed by several other TB’s and TB crosses over the next 35 years.  Her current horse is an 11-year-old Oldenburg mare that she started under saddle and is currently training at 2nd-3rd level.  She has been an amateur rider and CDS member for many years, and volunteered at a number of high and low profile shows and Olympic qualifiers.  More recently she has enjoyed scribing, and serving as a board member of the CDS Los Angeles chapter.


Anna is a landscape architect by profession, in business with her husband Richard Walker.  The firm of Armstrong & Walker designs municipal and commercial projects throughout Southern California.  They also teach classes in garden design using California native and drought-resistant plants.

Barbara Filkins

Barb Filkins is a long time dressage competitor with both her USDF bronze and silver medals. She can, most recently, be seen with her FEI mare Leana at shows throughout southern California. She has also been a long time member of the LA Chapter Board, having served in the late 80’s and now again for the past several years. Professionally, she consults in cyber security, specializing in healthcare and aviation.

Stephanie Gyure


Stephanie was born and raised in San Diego where she earned a degree in art at San Diego State. She moved to LA when she started galloping race horses. The horse she showed for 8 years was one of these TB's. Being a ring steward at the Olympics in '84 was her first experience with the job, and when she retired from the track, she became ring steward for the Cornerstone shows and all the LA Chapter shows. Stephanie have been on the LA Chapter board longer than she can remember, and she can be found in the awards booth at the CDS Championships. Now she also has a  craft business, specializing in fleece blankets and other equine related items, which can be seen at places like Equusfest, Horse Expo, and the Del Mar National. She also works with HorseCoinJewelry.

Kristina Harrison


Kristina Harrison-Antell fell in love with horses as a child and began riding at the edge of six, when she got her first pony.  In 1992, she discovered her life’s passion in dressage, and rode her former hunter, Gilligan, to the advanced young rider level.


Kristina imported Kantor, a Dutch Warmblood gelding, from Holland in the late nineties.  The team qualified for the 2003 Pan-American Games in Santo Domingo, Dominican Republic, by winning the Bayer/USET Intermediary 1 Championship held at the USET headquarters in Gladstone, New Jersey.  The U.S. Team earned the coveted Pan-American Team Gold Medal.


Rociero XV, a stunning white PRE (Pura Raza Espanola) stallion, owned by Margaret Carrera of Auburn, California, was Kristina’s most recent FEI partner.  With Kristina, Rociero in 2006 was named USDF Intermediaire 2 Horse of the Year, and placed third in the 2007 USDF National Grand Prix Championships, held in Gladstone, NJ.

Kristina and Rociero were awarded a grant from USET in 2007, which enabled them to travel to Olympic team coach, Klaus Balkenhol’s stable in Germany, in the fall of that year.  While there, besides training with Balkenhol, the pair competed successfully, coming second in the Grand Prix, at the CDI Oldenburg, among other top placings. Kristina and Rociero XV made history in 2008, as he became the first PRE in history to be invited to participate in the Olympic Dressage Team Selection Trials in San Juan Capistrano, CA.


Today, she continues to develop a variety of up and coming stars and continues to compete at the FEI level.

Marissa Krupa

Website/Social Media/Newsletter

Marissa grew up in Reno, Nevada, doing Pony Club, jumping, and eventing with her “free horse”, a chestnut mare named Sarah. After traveling around the world and living out of a backpack for a year, she moved to Malibu to complete her B.S. in International Business from Pepperdine University. After first establishing her career in Technology for the Entertainment Industry, she moved Sarah down to Los Angeles. Old age grounded Sarah, so Marissa fell for dressage, and she began taking lessons, volunteering at shows, and showing Training Level. She is now working towards debuting her 2013 filly, Rivahna, who she has raised from a weanling.
