Katie Ellerbeck

Founder of  RokCore Pilates & Yoga Studio.

with 18 years of teaching experience, Katie is a qualified CYQ Level 3 Pilates instructor, Reformer Instructor & Ashtanga Vinyasa Yoga Instructor!                                               

I began Ballet classes at the age of three and it was there, that I fell in love with movement and how it made me feel! I  loved to Dance and went on to train as a Dance teacher,  it was  during my training that I found Pilates and Yoga!

I began teaching Dance at 18 and qualified as an aerobics teacher in 2001, which lead me on to teach Body Combat, Body Balance and then finally my true passion and where my heart lies - Pilates and Yoga!

My dream was to have my own Yoga studio but never did I dream it would come true!

For me teaching is about making a positive difference to peoples lives. I hope that what my students  learn with me in class, will enhance their every day lives,  away from the studio also. Pilates and Yoga are more than just an exercise or fitness class, they connect the mind, body and soul and allow you to focus on yourself, breathe, release tension and generally improve physical and emotion wellbeing! Creating a more balanced lifestyle!

I am forever grateful to all my teachers who have trained me along the way, supported me and became my friend!

Amanda Houston

When I first arrived on a yoga mat I was mentally and physically exhausted.  I was young and restless, working long hours in television and partying a little too often.  I remember feeling overwhelmed with the breath, frustrated when I couldn’t get into postures and rebelled in meditation, but towards the end of class I would feel calm and more focused which kept me coming back for more.

My passion and curiosity for yoga continued to grow and over the years I have practiced a number of styles including Ashtanga, which led me to Mysore at Purple Valley in India.  I learned so much during this period but my rebellious nature wanted a more playful practice so I began exploring the different styles of Vinyasa.

Vinyasa flow gave me so much freedom, each class offered something new and quirky and it helped me build incredible strength in the mind and body.  I felt wonderful and wanted to learn more so I decided to undertake the 200 hour YTT with Peak Beings in Hawaii and in February 2017 I qualified as a teacher. 

Since my return I have been lucky enough to teach Vinyasa in London and Essex and recently I attended another teacher training course in Yin Yoga, which is a slower paced style that targets the connective tissue, the perfect complement to a dynamic (Yang) practice.  During the class we will use a combination of both styles to work the whole body, connecting the breath with movement whilst building strength and flexilbility, before winding down through blissful Yin / Restorative postures and meditation. Hopefully you will leave feeling lovely and nourished. 

Classes: Tuesday 7:30pm


Steve Johansen

I first discovered Yoga in February 2007, in an attempt to combat a bad bout of depression that I was experiencing at that time.

Initially drawn to Ashtanga Yoga a Vinyasa flow, which is a fast flowing energetic style of yoga, I soon realised that I wanted more from yoga than just the physical practice. Consequently, I began practicing other styles of yoga such as Hatha, Iyengar and Sivananda, with many different teachers. But kept being drawn back to Hatha Yoga, which is the base of all yoga styles.

After a few years, my practice had developed and my teachers began suggesting that I become a yoga teacher myself. They felt that my patience, enthusiasm and caring approach to the people around me, coupled with my strong practice, would make me an excellent teacher. After much deliberation and research, I finally decided to undertake the 200 hour teacher training course at CamYoga in Cambridge. 

Since qualifying in April 2014 I have enjoyed teaching Yoga at a number of locations and studios, thought-out Essex, teaching Classes, Private 1-2-1 sessions, Workshops, and now teaching Anatomy and Asana (yoga poses) on the teacher training program back at CamYoga, where I started my Yoga Teaching journey.   

Now a full time Hatha Yoga teacher, my love and enthusiasm for yoga hasn’t diminished, which leads me to be always learning and looking for new ways of developing my own daily yoga practice and improve my teaching skills, attending various courses and other classes and workshops whenever possible.

While my understanding of Yoga has increased, I still don’t do a lot of chanting or as my students like to say “OMing”, I have introduced more yoga philosophy into my classes, which still focuses on proper alignment of each asana (yoga pose) in a fun and encouraging way. Adapting the intensity of each class to the participant’s needs and skill levels. Ending all my classes with some form of or Shavasana, relaxation or mediation, leaving the students feeling energised but relaxed. 

Classes: Wednesday 9:15am

Luisa Rennie



I have been practising yoga for over 20 years and teaching for 14 years, specialising in mindful, alignment-based, breath-led dynamic yoga. 

The focus of my study and practice has been ashtanga yoga, vinyasa yoga, yin yoga, yoga therapy and vipassana meditation, and I have been blessed to study with some of the world’s leading teachers, including Mukunda Stiles (yoga therapy), Shiva Rea (vinyasa flow yoga), Tias Little, Uma Dinsmore-Tuli (pregnancy yoga and yoga nidra), Sarah Powers (yin yoga and meditation) and John Peacock (mindfulness and Vipassana meditation).

I am a British Wheel of Yoga Teacher, a Senior Yoga Teacher with Yoga Alliance UK, a pregnancy and post-natal yoga teacher and a Birthlight Baby Yoga, Level 2 teacher. I have been a mentor on the Yoga Campus teacher training course, assisting new teachers with their yoga teacher training, and marking essays. I have also worked with the Prison Phoenix Trust, teaching yoga and meditation to prison populations. I taught for five years at one of London’s top yoga studios, The Life Centre in London as well as teaching yoga to Oxford rowers, and specialist workshops on stress relief to Oxford University students. I have run UK based and international yoga retreats, which I will start up again in 2019 (now I’ve had my babies!).

All my yoga classes, workshops and retreats include detailed instruction, energising and relaxing sequences and a special focus on the breath. My teaching is all-inclusive and non-dogmatic but is firmly grounded in the philosophy of yoga, especially the practice of 'ahimsa' – non-harming, 'santosha' – contentment and 'svadhyaya' – self-study. 

My yoga classes are also infused with the Buddhist vipassana, or 'insight' meditation I practise, and often carry a strong therapeutic focus.

Natalie Diss 

My Yoga journey began 10 years ago teaching Body Balance with the sole intention of adding a stretching programme to my fitness routine. Three years later, after experimenting with fitness yoga, my passion for Vinyasa Power Yoga began.

I found a like minded training school to learn this powerful, energetic, form of yoga moving fluidly and considerately from one pose to the next using breath and every day English, which I believe eliminates elitism and confusion.

Through intelligent and considerate sequencing I wish to make a Power Yoga accessible to a broader audience encouraging participants to stop, take a breath, think and feel...... truly reconnecting with mind and body.

Join Natalie Tuesdays 9:30am & Saturdays 8:00am
