Dr. Derebery is a great physician. I have had extreme vertigo for for all of this year after a bout with the flu. I has been through the mill at KP, and they had just given up on me and told me I was on my own. I had to pay out of pocket, but the fee's a the House Ear Institute are reasonable. She did a through exam, reviewed all my KP records and started me a regime of Rx and Non Rx drugs that no one at KP had ever heard of. The drugs did not work, and ultimately she had to refer me to a Neurologist that Specializes in hard to diagnose vertigo. If my condition is permanent, so be it, but Dr. Derebery never gave me the bums rush, or failed to take to time to explain my prognosis. At least I know I have seen the very best in the field and was treated with respect. Thom Wendell (Hubbell)
