He was my endo for Cushings. He didn’t believe me at first because I didn’t look “cushings” enough. I was. I had a second tumor that he didn’t believe and refused to give me saliva tests when I asked for them specifically as I was cyclical. Again, I was Cushings from this tumor that he didn’t believe I could have. Arrogant, disregards patients opinions, condescending, he should never see a Cushings patient again. Because of his disbelief and arrogance my tumor could not be fully removed as it had grown large enough to be directly against the carotid artery and was not fully removed. It can never be fully removed now. His lack of action cost me. He needs to update his information regarding Cushings is he’s going to keep dealing with those patients.

I found this doctor arrogant and unwilling to listen to patient. My mom saw him as a cushings patient and he missed seeing obvious abnormalities in her blood work which luckily I caught Does not give complete details of procedure options.

Dr. Kline is an excellent Endrocrinologist. He listens, is very warm, explains things fully, knows his stuff thoroughly. We have ended a 35 year health issue of High blood pressure with resulting heart disease through Dr. Kline diagnosing the root cause (a rare issue) which may very well end up with full cure. Just waiting for this Coronavirus to pass so surgery can be performed safely. Would highly recommend him.

I found Dr Kline to be very knowledgeable and straight forward with his diagnosis, helping me to understand just what was going on with my problem. He was patient and kind and explained things very well. I had been referred to him by my Cardiologist, who had that foresight and cared enough to do so. I thank both Doctors profusely for working together as a team. Because of this, I am on the correct medications and doing much much better. I highly recommend Dr. Greg Kline.

Very Smart doc. Nailed Aldosteronism as the reason for malignant hypertension and put me on Spironolactone to bring down the bp. Collaborative and takes time thoroughly explain and follow-up. Can’t say enough good things about him and the staff. If you’re lucky enough to get him you’ll be in very good hands.

Couldn't figure out my diagnosis and was extremely rude

I am so grateful I was finally referred to Dr Kline's office. He nailed my diagnoses in 1 visit after I went on 3 years with no answer from any other specialist. My second visit seeing him he gave me a timeline of my procedures and my surgery and it happened exactly the way he said. No messing around with him, he says something will get done and he makes it happen. I felt very calm in the hands of him even though I was diagnosed with Cushing's disease (pituitary tumor) and I knew there was a long hard road of surgeries and recovery time ahead of me. All of his staff were so helpful and patient with my family and I always calling the office. The staff in the Foothill's hospital on the neuro ward were absolutely wonderful too. I owe my life to all of them

I cannot say enough good things about Dr. Klein. After having a terrible overall experience with my previous Endo, it felt fantastic to finally find one that is so compassionate, patient, and knowledgeable. I have Grave's Disease which was diagnosed at 16 years of age, which is very young for this condition (average age of diagnosis is 40-50), which has caused my case to be quite challenging. After failing several attempts with my first Endo at methimazole remission, and becoming increasingly more frustrated with her refusing to give me all the options available (She only ever talked about RAI, which I am not a suitable candidate for as I have Grave's Eye Disease), I stopped treating my disease altogether for years. I was convinced no one would give me the time of day, because I was so young, even though I have always been a bit of a medical nerd and know what I am talking about, and thoroughly do my own research.

Several years later, when I had to go in for an unrelated surgery but needed my Grave's controlled before that would be possible, enter Dr. Klein. He was patient and thorough with guiding me through all the available options, including Thyroidectomy, which I have believed for years is the best option for my case but could never get my first Endo to agree to it (she kept telling me it was too risky and they didn't do them anymore because of infections, which is a lie.) Klein's beside manner is fabulous, and I never once felt belittled, and he spoke in a way that showed he respected my own medical knowledge too. He is open to T4/T3 combination therapy as well, which if anyone reading is hypothyroid, they know how incredible that is. Finding an Endo who is open to ALL the available options, even if it may not be the most proven treatment, is like finding a unicorn.

I truly believe this man has saved my life. He gave me back my sense of self-confidence and medical autonomy. I cannot thank you enough Dr. Klein.
