I've been a patient of Dr. Guiang since 2010 - 7 years - and have nothing but great things to say about say about him. He's a kind, warm, and friendly doctor who always seems to go beyond the call of duty. He always shakes your hand and says hello before beginning an appointment. Dr. Guiang also offers alternative methods for pain management, loans out books, provides lots of handouts on health and wellness, and suggests helpful supplements. He takes a whole-person to approach care.

No compassion. Didn't even ask about my injury. Very arrogant.

Dr. G helped me in ways no other doctor has. He looks for the cause of problem rather than just addressing the symptoms of the problem. Because of him I feel so much better and he has improved my health more than even my primary care doctor has. Thank you Dr. G!

Dr. Guiang failed to listen to me explain my signs and symptoms at all, and once he heard fibromyalgia and lupus he basically kicked me out saying he doesn't consider those disorders painful. I felt COMPLETELY discriminated against. Poor treatment with a smug smile. Unbelievable.

Dr accused me of coming to him just to get drugs, especially since a 4-year old MRI of my back didn't show anything to warrant pain meds (his words!! Isn't the first thing they learn that you can't see pain on an x-ray?! I have ha chronic pain for 20+ years, and have multiple conditions that cause pain, and he told me my pain wasn't there?! He also told me EVERY month for 4 months that he could do a procedure very easily in his office to help my back, but never scheduled it!
