Dr. Daniel Glenn Doornink, MD

Just heard last night that my Dr. Dan Doornink is leaving Cornerstone Medical Clinic. So sorry, as far as I am concerned he has kept me alive and well for many, many years. Hope he has a happy retirement, will miss him. Barbara Trusley.

Dr.Dan has always been a doctor who looked after our needs,answered our questions. never hurried us. We are sad you are gone .Thank you Dr.Dan Gene and DOROTHY

Dr. Dan Doornick was both my husbands and my doctor for many years. He did not address serious issues my husband experienced over 5 years. We had to go to Virginia Mason in Seattle to a Neurologist to find the cause of my husbands problem. He had three times the amount of fluid on his brain than normal. They saw this with a Cat scan. So unprofessional that Dr. Doornick never followed through on searching for a cause for my husbands problem or making a referral to a specialist.

I have been a patient of Dr Dan's for several years. I have found him to be very thorough and straight forward which are things I value in a doctor. He is personable and offers good suggestions . I have been very pleased with the services & care with which Dr Dan has performed. I highly recommend him!

I was seen on time, after a smooth and friendly check-in. Dr Doornink was polite, organized and very knowledgeable about my medical history (I'm a new patient). He spent time going over my medical and family history. He never seemed rushed and helped educate me on how to improve/maintain my health. I was very impressed by his knowledge, professionalism and content of the visit.

Does not perform exams but bills for them. Just talks about himself, and misses the medical problems
