Dr Cahill is a treasure. And a brilliant Dr.
He found and cured an infection that no one else could find. And he has amazing stories about NYC back in the day.

After six years of my sons life battling a variety of symptoms and wrong diagnosis, we were referred to Dr. Cahill. After Mayo Clinic, Georgetown Hospital , Johns Hopkins and countless others over the six year period, Dr. Cahill successfully treated my son. We live in Virginia and we have sent no less than twelve other people to him and the majority were diagnosed and also successfully treated. The proof is in the pudding as they say! I don't know who I will recommend people to when he retires. I received another call from a stranger this morning asking to share my experience. If another Dr. has told you "IBS" run, don't walk to Dr. Cahill. IBS is quite frankly a lazy mans diagnosis--DONT SETTLE FOR IT! God bless you Dr. Cahill. My family will always be eternally grateful we went to you!

Cahill is good at finding only some parasites. If you have Strongylodies or some other tissue parasites, he will not find it. Also, his Eh diagnosis is not on sot on always, and he is horrible with his dose of meds, which is always wrong. I had to go to another doctor to get the right meds for the ameba.

Dr Cahill is outstanding. My gastro Dr couldn't figure out what was wrong. 24 hrs after seeing Dr Cahill he had it all figured out and proceeded to eliminate the problem. I am VERY grateful!

I have had amoebas for a year now, trying to get rid of them has been almost impossible! Cahill is very knowledgeable and has been very patient with me so far and we are still working on getting me back to my normal self again. He has gotten rid of this parasite before for me and I know he will surely again :)

He's the only one who repeatedly solves parasite problems that other doctors and labs miss!

I can't say enough good things about Dr. Cahill. He was the ONLY doctor who was able to give me a correct diagnosis. I went to other specialists for months only to be told I'm "fine" while I was in so much pain and felt like I had the flu everyday. Parasites cause serious damage and the strangest symptoms, but he is the only doctor who was able to help me. This world needs more doctors like him and it's a pity that no other doctor considers parasites or has the knowledge to treat them properly. This man is a Saint and I owe my good health to him! I hope other Doctors take interest in his expertise and become more educated in the field of parasitology, especially the gastroenterologists who just sum everything up to IBS.

This is a really amazing doctor. He diagnoses you very quickly and then helps to get the proper care. If you have a parasite, or never even suspect it, but have so-called IBS or gastro issues, and more seriously other things such as sleeping issues, indigestion, bloating, weight loss, loss of appetite, itching, rashes, which are often unexplained, whether they came on suddenly or gradually, go see this doctor. I would strongly advice against seeing typical doctors or gastro "specialists" in particular. They just dont know how to diagnose anything. They have no knowledge of parasites and think they exist only in some OTHER country. And they will give you steroids and other drugs like humira , which will destroy your gut and immunity. Take it from me. I wasted so much time, running from doctor to doctor. Until I had the fortune to see this doctor. There just are not many doctors of Cahill's caliber!
