Most decisions Dr.Cook made I felt were based on my past history and not the present. I understand the reason in this action however I am not sure he listened when I explained what took place. He did treat me on the side of caution which is what a good Doctor would do.

Dr. Cook was the best decision I ever made. He is so compassionate.

Dr. Cook agrees with me on my reasons for anxiety, including my speech problems and when I recently had a problem with my local insurance agency after I was sued by a next-door neighbor for damage to her two cars which she said was caused by acorns falling from my yard tree, Dr. Cook immediately completed and signed a medical form my insurance agency insisted being done after the Agent Ziemba heard me speaking nervously and sent me letters threatening to cancel both my house and car insurance within 30 days if I didn't comply with his ridiculous and unfair demands. The car insurance wasn't cancelled because Dr. Cook did the form and I delivered it to the Agency and sent a copy to Erie Insurance immediately. The house insurance was ordered cancelled by Ziemba because he claims, but could not verify, that he saw "mold" on my garage roof. I don't know what I'd have been able to do without Dr. Cook's help which I needed.

I switched PCP three years ago from InterMountain Medical and it was the best decision I could have made for my serious health problems. the previous Dr let serious medical problems go untested and untreated.

Dr. Cook is amazing. Always concerned, caring and considerate. He always knows exactly what is happening with my other doctor visits and helps me make decisions on what direction I might choose to take. He doesn't tell me what to do but provides me with information. I trust his judgement and feel that he takes care to know I am a person. He makes me feel valued and worthy. I have had doctors who have treated me with no respect and I cannot reinforce enough how important it is that physicians respect their patients.

I was unable to see my regular doctor so saw another doctor; while he was very nice, he was somewhat dismissive of my concerns about what he was prescribing and did not give me sufficient information. When I found it on my own I insisted on stopping the antibiotic he prescribed. Further, he switched me from one antibiotic (that was not the right one) to one I did not want and did not communicate this to me so I spent too much time taking an ineffective antibiotic anyway. While I appreciated getting in to see someone right away, I don't think the treatment process was handled well or clearly.
