Dr. C is the best! Weve used him for 30 years! We love him and his practice. Dont know what we will do if/when he retires!

My husband saw Dr. Christiansen for a bit back in 2009. He was a dinosaur back then. He took my husband off of all his Cystic Fibrosis meds, telling him theres no proof it works for adults. Husband ended up in the hospital for a week because he developed a lung infection. Christiansen showed up twice during the hospital stay, then had some lady come see my husband the rest of the visit. We were charged for his visits all week, when he showed up twice. His office staff was terribly rude. Then Christiansen dropped him as a patient. Which was fine because we discovered a wonderful Pulmonologist who runs the CF Clinic in OKC and have been going there ever since. Dr. Christiansens bed side manner is lacking and hes stuck in old ways of thinking. Medicine has made advancements. Christiansen, not so much.

If I could give less stars, I would. Apparently Dr. Christiansen was Dr. Lavons back-up person. She is now retired so I called to get an appointment to switch doctors. The rude hag that answered the phone told me that Dr. Christiansen is not accepting any of Dr. Lavons patients under any circumstances for any reason. Nice to leave her patients on the sidelines you jerk.Of course, hes like 80 so maybe thats why he doesnt want to see anyone else....maybe hes a nice guy but the seawitch that answers the phone needs an attitude adjustment.

Excellent doctor and staff!
