Dr. Emilie Perras

Owner/ Founder Chiropractor Downtown

Let me introduce myself, my name is Dr. Emilie, and I’m a family wellness Doctor of Chiropractic in Ottawa.

I’m a small-town French girl from Penetang, who later moved to Ottawa for university, then headed to Toronto for post-graduate Chiropractic school. To get to know me better, here are three things that I really like (other than my husband Martin, and my kids Ori Ani and Nico, of course!): I love to read, I’m crazy about chocolate and I love being around kids; especially when they’re getting healthier naturally!

Many chiropractic patients have a miracle story about chiropractic. Mine is different – my story started when my mom started bringing me to a chiropractor when I was 3 years old! When my mom was pregnant with one of my brothers, she quickly gained 50 lbs, all in her belly. It literally looked like she had a watermelon under her shirt. Not surprisingly, she began experiencing severe back pain. She started seeing a chiropractor and had such great results that she decided to bring the whole family in for check-ups. From then on, myself, my three brothers, and my mom went to the chiropractor regularly for wellness care. I feel blessed that my mom learned about the importance of chiropractic early on. “As the twig is bent, so grows the tree.”

When it came time to choose a career – it was a natural choice. I wanted to help people be healthy, and stay healthy through chiropractic. My mission now is to help other families achieve total health so they can live life to their full potential. It’s strange how life is, because now people come to see me for pregnancy care and family chiropractic. Also they come to me with their headaches, migraines, chronic pain, neck pain, shoulder/arm pain, whiplash from car accidents, ear infections, asthma, allergies, numbness in limbs, athletic injuries,…to name a few!

Our patients often thank us for “curing” them of their health problems. But I can’t really take the credit. What I do is perform a specific spinal adjustment to remove nerve pressure, and the body responds by healing itself. We get tremendous results – it’s as simple as that!!

My qualifications – I’m a Summa Cum Laude graduate of Canadian Memorial Chiropractic College with a Dean’s Honours List Bachelor of Science degree. I also attend postgraduate seminars constantly to stay up-to-date with the latest techniques and research. Through additional study, I attained a certification from the Academy of Family Practice and Council on Chiropractic Pediatrics. I’ve been entrusted to take care of tiny babies to high level athletes to seniors – and I’d be happy to take care of you!

My team and I are here to help families achieve better health naturally.

God bless,

Dr. Emilie Perras, D.C., B.Sc.

Martin Michel Perras

Owner/ Founder Acupuncturist & TCM Practitioner Downtown

Bonjour! My name is Martin Perras (yes that is French Canadian last name!) and I am a Registered Traditional Chinese Medicine practitioner and acupuncturist. I am very blessed to be the co-owner of Oaktree Chiropractic, Acupuncture and Chinese Medicine – one of busiest clinics in Canada.

I have three gorgeous (and active!) kids and an amazing wife, Dr. Emilie (Chiropractor) who is my partner in all that I do. I strive to find room in my life for the things that feed my soul like spending time in nature, running, and making my family’s nutrition a high priority by ensuring that we choose good quality, mostly organic, whole foods based meals. But it’s tough! I often struggle with balancing getting enough sleep with accomplishing all I want to do in a day. I get tired and all I want to do it eat chips and watch Netflix. But long ago, I made the decision to learn to play full out, be “all in” and to have the life that I know that I am meant to have. I want a life full of joy, energy and the strength to go after my dreams and CREATE the life I want for myself and my family. And I am passionate about helping people heal, remember what life is like without pain and learn to live life to the fullest too!

But getting to this point has been a gradual process. My life wasn’t always centered around healing like it is now. At the age of 25, I had hit the jack pot. I was the owner of a very successful company and I had clients all over Canada and the US, including companies like Microsoft, Coke, Boeing, Ford and many more Fortune 500 companies. I had great employees and life was good. Business was amazing, yet something was missing.

My fire was slowly dimming; I wanted a career that was more about serving and helping people. I decided to sell it all and look for a career with new meaning. With the influence of my beautiful and brilliant wife, I started to look into health care, as I had always been very passionate about health. After careful consideration, I chose to study Chinese Medicine because of the principles, the beliefs and the depth of what it offers.

Chinese Medicine is all about prevention – a principle which is very important to me. There was a time in China where the Chinese Medicine practitioners would only get rewarded financially when their patients were healthy. This encouraged them to focus on getting the patients well and then keeping them well through prevention.

Acupuncture and Chinese Medicine has healed people for over 3000 years. I’m excited about what acupuncture offers with a holistic approach: mind, body, and soul. It can help with a wide variety of physical and emotional conditions such as: Addictions, Arthritis, Cancer, Depression/Anxiety, Diabetes, Digestive Issues, Headaches, Heart Disease, High blood pressure, Fatigue, Fertility, Menopause and Weight loss. Ask me how it can help you!

God bless,

Martin Michel Perras, R. TCMP

Dr Katrina Greer

Dr. Katrina Greer

Chiropractor Orleans

Hello! My name is Dr. Katrina Greer. I was born and raised in the small town of Kemptville, just outside of Ottawa.

My chiropractic story started a long time ago. Before I was born, my dad sought chiropractic care to correct postural issues. Once he understood the importance of a healthy spine for all ages, he decided to introduce my brother and I to chiropractic when we were born. I had my first adjustment at only 2 weeks old! From then on, regular chiropractic treatment became part of a healthy lifestyle for our family.

Looking back, I am grateful for my father’s insight. I started karate at age nine and loved it so much I pursued it all the way to Canada’s National Team. There were too many instances to count where I was happy my chiropractor would be helping realign my spine after training and competitions!

Practicing within the philosophy of martial arts, I became dedicated to becoming the best version of myself, and devoted to helping others do the same. Achieving my black belt meant that I was finally a Sensei, translated from Japanese into “teacher” or “doctor”. A career in chiropractic, where I would be fortunate enough to educate and heal others, slowly became the natural path for me.

While completing my studies, first in Human Kinetics at the University of Ottawa, and then at Canadian Memorial Chiropractic College in Toronto, I remained active as a kickboxing instructor and member of the health promotions team on campus.

When I am not with family and friends, I can be found kickboxing, dancing in Zumba class, exploring nature, or out on the slopes. I love using my skills and passion for chiropractic care to reduce pain and disability, optimize function, and improve the quality of life of my patients!

I’m looking forward to working with you!

Hannah Lohnes

Hannah Lohnes

Acupuncturist Orleans

Hello! My name is Hannah Lohnes and I am a Registered Acupuncturist. I grew up in a small community near Bridgewater, Nova Scotia. In 2009 I moved to Ottawa to study at the University of Ottawa where I completed a 4-year Honours Bachelor of Health Sciences.

After finishing my undergraduate degree, I had to figure out what was next. And to be very honest, I wasn’t sure what that was! I did know I wanted to do something in healthcare.

Many Acupuncturists will tell you that they became interested in Traditional Chinese Medicine (TCM) through personal experience, or having someone close to them with a positive experience. This however, is not my case. I had never had acupuncture, nor had any of my friends or family try it. In fact, it was a well known fact that I was terrified of needles (luckily I quickly learned how thin acupuncture needles are compared to needles you’ll find in a doctor’s office!). But I was curious. I had to drive by a Chinese Medicine school every day to get to work. It was as simple as that. Curiosity! Within 4 days of walking into the school to inquire about their programs I was sitting in class, and my curiosity continued to grow.

Since finishing school I have gained valuable training with an amazing mentor and friend, worked in a clinic specializing in cancer and acupuncture and have started teaching at the school from which I graduated.

The human body has amazing innate powers including the ability to heal itself. Sometimes it just needs a little encouragement and coaching! I love that Acupuncture and TCM considers the patient from a holistic perspective, values the prevention of illness, and promotes healing in a natural way. It is truly amazing to be part of peoples’ path of health and wellness!

When I am not in clinic, teaching or studying, I continue to be curious and active! I enjoy activities such as hiking, dragon boating, kickboxing, salsa and indoor bouldering, and am always looking to try new things as well! Traveling is another passion of mine. Slowly but surely I hope to visit as many countries as possible.

I hope I have piqued your curiosity, and look forward to helping you!
