During a break in university, I backpacked throughout Europe, India, Nepal, and South East Asia. I met my husband waiting for a bus in Egypt. We later lived and worked in Thailand and Vietnam for many years (yes, I brought my 3 week old daughter back to Saigon after her birth in Vancouver) and since returning to North America, have traveled to Turkey, Costa Rica,  Europe, and India with our children.

Sibylle Tinsel, RN, CTH® – Nurse Coordinator

What do you do at TMVC?

As the Nurse coordinator, I liaise between our nurses, doctors, administrative staff and, first and foremost, our clients, to help them get answers to medical questions and to plan the best approach to prepare travellers for their upcoming adventure.

Part of my role is keeping staff up-to-date about global health issues such as disease outbreaks or other travel alerts or changes in TMVC policy.  As a travel nurse consultant and immunizer, I also very much enjoy my clinical role and interacting with our diverse clientele.

What did you do before you joined TMVC?

I grew up in Germany and went to nursing school there. I worked as an RN in Germany and Canada, and then took a break to be a stay-at-home mom while my children were younger. I’ve been at TMVC since 2010, and I really enjoy it. My love of travel and the health care field make it a perfect mix for me.

What do you do when you’re not at work?

I am currently enrolled an online nursing program at Athabasca University.

When not at work or in school, I love to be physically active.  Running and bike commuting are my main sports.  I also enjoy cooking and baking.

I’ve travelled extensively in Asia and Europe and Latin America. I once rode my bicycle through Mexico, Belize, and Guatemala and through the Andes to the end of the road in Ushuaia, Argentina.

Susan Petford Office Manager, Victoria

What do you do at TMVC?

As the office manager in our Victoria branch, my biggest challenge is coordinating schedules, whether it’s for our occupational health clients, or group travel consults for schools, church groups, or sports groups. Our objective at TMVC is to accommodate client requests, so I find ways we can be flexible with our schedule so we can make it as convenient as possible for our clients.
I love getting to know our clients, finding out where they are going, what they will be doing on their travels. We have a lot of repeat clients, and it’s great to keep in touch with them. We have a great rapport with our clients and as most of us in the office have lots of travel experience, we often offer them personal travel tips.
There isn’t a day that goes by that I don’t learn something. It keeps the job interesting and fun. I’ve been with TMVC for over 7 years, and I still love coming to work every day!

What did you do before you joined TMVC?

I spent 16 years as a travel agent and agency manager. It was a career that was constantly changing, and it was very challenging and very rewarding. Before that, I was in retail management at a major drug store chain.

What do you do when you’re not at work?

My previous career gave me the wonderful opportunity to travel to many great places around the globe. I continue to travel as much as possible. Sometimes, it’s just a day trip on Vancouver Island, but there’s always something new to see and do.

I spend a lot of time with my family, including my five awesome grandkids. I love cooking, gardening, and shopping–it’s a tossup between fresh, local produce and new shoes!

Kirsten Lawson, Medical Office Assistant

What do you do at TMVC?

I’m a medical office assistant and often the first person our clients see before they meet a doctor or nurse. I help our clients by creating a pleasant environment and making sure they feel at ease.
I also keep the clinic running smoothly so our doctors and nurses can focus on patient care. Sometimes I also work in our customer service department call center, making appointments and providing general information for people when they phone in.
I still get excited when I see people taking trips of a lifetime. In a sense, their trip begins with preparation, and we are part of the overall experience for them. I especially enjoy being able to work at all five of our lower mainland offices and meeting all our clients.

When did you join TMVC?

I’ve been at TMVC since the beginning of 2013. Previously I worked as a medical office assistant for ophthalmologists in Vancouver, and did administrative work for a retirement centre in Burnaby.

What do you do when you’re not at work?

I’m fortunate to have many close friends, and I love to spend time with them. I love to bake, and my coworkers tell me they are really happy when I bring in brownies or macarons. I also like to take road trips, attend concerts, try new restaurants, and experience every neighborhood in Vancouver.
