Dr. Singer is thorough and very knowledgeable. He’s also patient and pleasant to interact with.
They helped me when I was at a point in my life. I didn’t know what to do. They were very nice nice and got me in right away and I’ve been with them now for a couple years and I feel great. I haven’t felt this good in years thank you to the staff And Doctor Singer
Best Doc and staff ever!
Thank you always. You guys are the best!!
On time. Very complete
For the first time in two years I have hope. I was exposed to life threatening levels of chemical toxins and no other doctors I talked to were willing to take my case. Until Dr. Dattoli I had been abandoned by the health care system. She was not only willing to help me but within the first few minutes understood the underlying medical condition. Additionally, Dr. Dattoli was compassionate and caring. She is more than a trained medical doctor. She is a physician. Something rarely seen since the government started prescribing health care protocols. I feel blessed to have found Dr. Dattoli. I had my first consultation with her on 23 December. The best Christmas gift ever. Mark Boyter
Dr Singer is the best and only Doctor that works to find the cause rather than treating the symptom. He saved our son's life years ago. Our entire family continues to be healthy and the only Doctor we trust with our health. If you want to learn more about your body and overall health or need help treating a chronic condition then look no further. He is a true knowledgeable professional with extensive years of experience who truly CARES!!
Dr. Singer is a great advocate for finding the root problem of your health concerns and treating that issue vs. just treating the symptoms of the problems. If you have a chronic condition that you can't seem to get to the bottom of, Dr. Singer can help! He has helped our family with IBD, Psoriatic Arthritis, Hashimoto's, hormone balance and chronic infection issues. Many times just simple options like diet changes and adding some basic supplementation have made all the difference - things that our standard doctors and specialists never suggested.
He is the BEST. He takes time to explain everything and he CARES
I am so happy I found Dr. Singer. I have been struggling with Long COVID for 3+ years, and have been to more doctors, hospitals, clinics etc. than I can count. I am just starting my recovery, but I have improved more in 3 days with Dr. Singer than the last 3 years combined. Highly recommend, it's worth every penny for me to finally start getting my life back!
Dr Singer is the only doctor I have seen that is able to get to the root of the problem. It does not matter what the health issue is, he is able to figure it out. I have not felt this good in years. I highly recommend Dr Singer!
Dr. Singer listens and understands. I don’t know what I’d do without him.
Dr. Singer and his staff are excellent. They provided exceptional care when my mom had pancreatic cancer. Dr. Singer’s extensive knowledge of medicine helped us consider various treatment options for my mother.
many helpful suggestions to look forward to
I had a number of concerns. Dr. Singer patiently listened to them all. I wanted some blood tests Dr. Singer wasn't familiar with, so he looked them up and then wrote an order for them. I feel like I'm on a better path because Dr. Singer is my physician.
Dr. Singer is the most knowledgable doctor I have ever met. He explains issues, test results and options very well and has been notably familiar and informed in all areas of traditional and holistic treatments and recovery for me with my late stage cancer. I have received high dose vitamin C and ozone through his office and I definitely attribute my good health and stamina to his advice & suggestions. I would highly recommend having him on board for any medical needs. Randi Sehestedt

I trust Dr. Singer 100%. Now that I no longer live in Colorado, he is only a phone call away and remains my best doctor ever. He also has a great sense of humor and can soothe my anxiety with a humorous quip.
Highly recommend! Thank you Dr. Singer for helping me and giving me a complete layout of my health. Going over everything one by one helped me understand what it going on with me.
