Janet ValenzaInstructor | Since 1995
Health, fitness and well-being have long been part of Janet’s journey, which began with nutrition in Jr. High and competitive distance running in high school and college. As a collegiate athlete, Janet was ranked 10th in the nation in the 5K and 3rd nationally in the 10K, graduating as magna cum laude in Biology and pre-medicine. Athletics took a back seat as she completed podiatric medical school, graduating pi delta, (upper 10% of her class). After her formal medical training, Janet re-entered the competitive running scene, primarily in road racing. Her specialty in her Houston private podiatric practice was biomechanics and sports medicine, which fit nicely with her competitive running. Her greatest achievements were Gulf Athletic Coast Runner of the Year, (based on time and placements of road races over 1 year), and twice qualifying for the Olympic Trials in the Marathon, (2:48:45 and 2:49:15). Her coach was a PhD in exercise physiology, Dr. Robert Vaughn, and her teammate was Francie Lareau-Smith, 5X Olympic competitor. Training involved not only running, but also resistance training, plyometrics, form drills, and, of course, nutrition and stretching. Janet began taking yoga classes to further her running career, but little did she know the depth of the practice, until she entered the yoga world. She took a sabbatical from her podiatric medical practice in 1995-1996 to travel to India, where she completed a 6-month training program under her teacher, Sri Raghuram, at the Vivekananda Prakushan Kendra. There, she became a yoga therapist and learned all aspects of yoga teachings. When she returned to the U.S., she provided private therapeutic yoga sessions, while also resuming her medical practice. Becoming a mother late in life, Janet retired from podiatric medicine just before her son was born. However, when her son started Montessori School at age 4 ½, Janet made use of her yoga training, teaching many yoga classes of all kinds and doing private therapeutic yoga, while also providing private wellness sessions in nutrition and strength training. About a decade later, Janet added Tai Chi to her repertoire, receiving her teaching certificate from the Tai Chi for Health Institute. All in all, Janet has taught Yoga for 23 years and Tai Chi for 5 years, in many places, including The Clubs of Cordillera, Hill Country Montessori School, (students, parents and teachers/ administration), Aloft Studio and at her own studio, the Thoughtful Living Center. She is very happy to be a part of The Center for Fitness community and she loves what she does and loves connecting with people through health and well-being!
Our Yoga Instructors
Cheryl SmithInstructor | Since 1989
Cheryl Smith started teaching group fitness with our founder, Gail Sears, in 1989 (back in the "Auditorium" days) and into our current location. For 19 years, with certifications from ACE and the Cooper Institute, she taught a variety of classes including Step, Water Aerobics, Low Impact, Pump and Interval Training classes. When yoga came to the Center, she began an exploration with teachers Kim Chica and Patty Williamson, and naturally, studied under them. But for a few years, teaching took a back seat to her "day job" as Co-Owner/Director of Camp La Junta for Boys in Hunt. Continuing her study and practice of yoga "on the side", however, she finally earned her 200-hour Yoga Teacher Training certification from Kripalu Center for Yoga and Health in Massachusetts. A firm believer in wellness, as a part of "wholeness," Cheryl seeks to make yoga accessible to all levels of experience and body types by promoting conscious awareness in all parts of class and by providing modifications to enhance a student's unique experience and exploration of their best yoga practice, truest self, and fullest life.
Maxine SandsInstructor | Since 2017
Maxine Sands achieved her 200-hour yoga certification in 2017. She is also an ACE Certified Group Fitness Instructor and CETI Cancer Exercise Specialist. In addition to her fitness certifications, she holds a degree in Registered Nursing, with a specialty in Adolescent Mental Health. Maxine’s interest in yoga grew out of her love for variousfitness formats, but it soon produced personal development and spiritual growth, and a deep desire for passing on knowledge of this incredible practice.
Having come into yoga as an older student and then later as a teacher, she has moved past pre-conceived notions regarding ability. She uses mind body principles in addition to the traditional logic, philosophical, and historical aspects of yoga, helping students to move past obstacle and discover their own individual style and form.
Debra ParmleyInstructor | Since 2019
Debra Parmley is a long-time resident, not only of Kerrville, but as a member of The Center for Fitness too. She started exercising with Gail Sears in the early 1980’s and began her yoga journey when Gail first introduced yoga at the TCFF in the late 1990’s. After several months she noticed increased energy levels, stronger muscles, and greater flexibility. She returned to working full time in 2007 and was not able to keep up her yoga and regular exercise schedule. After spending 10 years working for various nonprofit agencies in Kerrville, including Schreiner University and Big Brothers Big Sisters of the Texas Hill Country, she realized that she was neglecting her own health. The result was increased stress and joint pain along with the inability to get a good night of sleep.
Debra didn’t like the direction her life and health were headed so she decided to make a change and pursue her dream of becoming a yoga instructor. Yoga offers many benefits beyond the physical; there are emotional and spiritual benefits as well. She wants to help others experience the benefits of yoga and being an instructor allows her to combine her love of teaching with the positive feeling she receives by helping other people. She has completed a 200-hour yoga certification with Patty Williamson of Lizard Dreaming Yoga in Fredericksburg.
Dana CardwellInstructor | Since 2016
Dana Cardwell is a Licensed Professional Counselor in addition to a Certified Life Coach, Personal Trainer, and Yoga Instructor. Her goal is to incorporate integrated medicine in our community to decrease mental and physical problems.
She describes her program as "Emmanuel Yoga: Yoga for stress, anxiety, trauma, and/or addictions”. Emmanuel Yoga works on calming the amygdala area of the brain: the fight, flight, or freeze area that generally operates on your unconscious level. “By practicing Emmanuel Yoga, we will come together (yoga means union) to know God is with us while creating strong bodies and balanced minds to lead a happy life”. She earned her 200-hour certification from The Yoga Institute in Houston.
Dana teaches Paddle Board Yoga on the Guadalupe River. This is a gentle mindfulness class with easy yoga poses. No previous experience is necessary - think of it as Paddle Board 101 and Yoga 101.
Rick TrzcinskiInstructor | Since 2007
Rick Trzcinski began studying yoga in 2007 when he attended a weekend workshop “Yoga for a Healthy Neck and Back” with Dr. Mark Uridel.

Research has shown that iRest effectively reduces PTSD, depression, anxiety, insomnia, chronic pain and chemical dependency while increasing health, resiliency, and well-being. Rick is a level 2 trained iRest teacher. He has been teaching weekly chair/wheelchair yoga at the Kerrville VA to the Alzheimer’s / Dementia group and other in-house patients since 2010. He also teaches a VYP Mindful Resilience Yoga class at his studio for Veterans struggling with PTSD and / or Trauma. This class is free but is for Veterans only.
