No no no. Harmful, fake tests, fake reviews. If you want to waste a bunch of money on garbage- go here. Dr. Klein will temporarily make you feel better by putting you on “feel good” hormones and selling you his garbage sugar pills. I don’t know how they get away with buying off reviews but they clearly do because my REAL reviews keep disappearing.

If you want a snake oil salesman that will suck you dry to the very last cent- Stages of Life Medicine with Dr. David Klein is for you!
This office is for nothing except greed. If you believe ivermectin will prevent covid this place may be for you. If you have a brain, heart, nervous system or real desire for healing/ run far far away.

Dr. Klein is absolutely a selfish quack as many have commented. He puts all of his patients on a plan to milk them and their insurance companies is the best way possible. He tells his patients they need to buy dangerous steroids and supplements from him and only he can diagnose your problem (make up something to get more money from you). I have overheard him pushing the same supplements he pushed on me that actually ended up severely physically harming me.
If you look him up, he spent a year in jail and has been cited many times by the medical board. There is nothing regarding the hypocritical oath that this man cares about or follows except well, being a hypocrite.
He will not help you or care about your well being in any way.
Run run run far far away.

I have been going to Dr. Klein for 3 years now. He is brilliant. He is a businessman as well as a physician. The supplements he sells are in the area where people can come in, as if a store, but when you are not seeing him by appointment, strictly a good location in the building. He treats patients by studying their labs. I wish I had him as a G.P. but he wants you to have your own G.P. He certainly has done more for me than my G.P.s I continue to see my Cardiologist - my usual physicians tell me my labs are 'perfect'. Gee, I wonder if Dr. Klein has anything to do with those perfect labs!!!! BTW, I am almost 78 years old, diabetic II as well - but I know that I am better with Dr. Klein than without him. Is he a bit brash, probably - who cares, I didn't hire him as my specialist because of his personality. Quack? Call him what you must. I'll take him and his knowledge and his suggestions for my health anytime. Waiting a long time? You bet, so bring a book or whatever you use to pass the time. Personality at the front door? O.K. Iris doesn't smile much but she is being paid to do a job and she does it well. Also, after she knows you a bit longer, she is full of smiles. Do your body a favor - listen to Dr. Klein; Oh, he never said you have to purchase his nutraceuticals!

Dr. Klein left me waiting 2 hrs after my appointment time when his nurse came in and said he was going to lunch. Bottom line, HE DID NOT WANT TO SERVICE ME BECAUSE I WANTED HELP IN HEALING WHICH TOOK TIME AND EFFORT. HE WANTS THE 10MIN PATIENT THAT PISSES IN A CUP AND HE WRITES A SCRIPT FOR OPIOIDS AND CHARGES $250. POS...THANKS DR. KLEIN....GOD KNOWS!

All I can say is I was shocked as I left. I have never been to such a quack. From the minute I walked in, the only thing the older lady at the front desk spoke to me was asking for payment. No smile, nothing. Very rude. I sat in the room in the back for an hour and 15 minutes. He finally came in. Managed to fit multiple cuss words in, called me sweetheart and was so full of himself. It became obvious pretty fast that hormones are simply gravy money for this guy and he has no idea what he is talking about. It was like a snake oil salesman. After a short time, I was walked to the back of the building that is his exit door and just happens to be his supplement store. He grabbed multiple items off the shelf that he said I needed, each costing around $30-$40 a bottle. He said that I needed to come back in 30 days to discuss my condition again. Funny, all those supplements were 30 day supplies. I politely said no thanks and got out of there. Please find a real doctor. I wasted $465 for my initial visit (that was just over 10 minutes with him). If you go to him, he will just sell you his pills and tell you that you will have to keep coming back for him to work your condition.

Unprofessional. Waste of time and money. Clueless on natural cures.
