Who we are

The Trim up story

The idea to start these group tours came about after Kirsten went alone to Mexico for her own bariatric surgery.

The service and care that she received was exceptional and highly professional. Kirsten thought more Kiwis and Australians would be open to heading there if they travelled together and she was right. 

Kirsten was born to travel but forced to work until this concept was created and now she has combined the two and found her dream job helping other’s realise their dreams at the same time.

Centro Médico Premier is a modern full-service hospital certified by the Mexican Government. This facility is dedicated to performing a large number of weight loss procedures each year. Built to always provide quality care and high medical standards while being known for its excellent track record.

At Stop Obesity we make sure we use only the best facilities equipped with the latest technology and service. Our surgeons and staff work seamlessly with hospital physicians and nurses to provide a safe and enjoyable experience for our patients.

Our Surgeons – Tijuana’s leading medical professionals

Mexico Bariatric Center and Stop Obesity have amazing, board-certified surgeons that only perform 3 to 4 surgeries per day. With lead surgeon Dr. Ismael Cabrera working from both clinics.

Most medical centers in Mexico (and the rest of the world) can do 7 to 8 surgeries per surgeon/per day – this high through-put of patients can result in an increased complication and failure rate. Our highly qualified surgeons take their time and care with each and every patient ensuring a successful outcome for each surgery.

Aftercare service with Kendall North


Registered Health Professional, Educator, Presenter, Facilitator & Specialist Behaviour Change Coach


Kendall North facilitates & supports those undergoing their health and weight loss journeys. I’m here not simply just as I’m qualified to be. Having grown through an incredibly turbulent journey in my relationships with weight, food,  exercise, body image, self, & health, into a place of self-nurturance,  gratitude, healthfulness, & freedom, I want to support you to experience the same opportunities.

I couldn’t find the help I needed solely within the medical model of a+b=c. I had so many powerfully rebounding issues around food, weight, & self-esteem which the medical equation didn’t & couldn’t account for. Issues that shrunk my quality of life but had the opposite impact on my waistline. Even as a Dietitian & Fitness Instructor with all the ‘knowledge & know-how’, I couldn’t achieve a consistent & sustainable change in my own behaviour.

I discovered not only for myself but many clients, colleagues, & whānau, that prescriptive diets & exercise plans have a place, but are simply not enough to complete a full transformation of a long & unhappy history around weight, food, exercise, & self. One of the hardest things I had to learn & action was to go beyond the ideas of calories, burnt, earned & conserved.

I needed to dig a little deeper, look a little further into what was happening for me & uncover a wisdom that lived inside me, not inside any single quick fix someone tried to feed me, & which I would so desperately race to consume. It has taken me a lifetime of lessons, 19 years professional experience, several qualifications (Including nutrition, clinical dietetics, fitness, teaching, & behaviour change), & becoming the mother of two with incredibly different personalities, to have acquired the depth & breadth of knowledge, skills, & strategies required to design, build, & deliver coaching that changes your life, not just your body. My services focuses on the health & lifestyle needs of people post bariatric surgery.

It offers the opportunity to write your own next chapter with appropriate resources to address the weight of psychological resistance, social oppressions, emotional, physical, & existential pain, other diseases & frustrations, & of course the nurturance of your now changing body. Remembering bariatric surgery is performed on your stomach, not your mind or environmental factors. This programme is about learning to take care of yourself holistically (internally & within your environment). The theory infused here is applicable to almost anyone & all health improvement goals throughout a lifetime. So, you can freely share the wisdom you gain with friends, whānau, & others seeking to improve their health & life.
