Dr. Zeng is absolutely knowledgeable and professional. I've tried many acupunture clinics in Ottawa and I have to say she is the best one to go to. Very professional treatments and very dedicated and attentive to your unique needs and preferences. I feel in great hands. I've had chronic problems with my back for 6 years and she made in better in the first treatment, felt even better after the second. She's taking care of my digestive issues at the same time. I'm a pretty critical person and I only have good things to say about my experience with Dr. Zeng. I will keep on going to see her whenever a problem arises Also: this is not a spa and she's not trying to get you on a plan.
