Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

The time and attention and information provided pertaining to my situation were the things that stood out most for me not only in my first visit, but all the appts I have had with Dr. Diamond since. He explains the test results and the medications in a way that is understandable and answers my questions fully. I also like the fact he is direct but also positive. I do want to include the office staff who are also so positive and supportive. I am so grateful I found Dr. Diamond through reviews.

He saved my life pt 2
He ordered the scans and the tests and then came surgery with an awesome surgeon that dr Diamond and his staff set up for me and I had a diagnosis and treatment plan and I’m still breathing today because of this doctor and his staff. I trust Dr Diamond with my life because he’s saved it and I will be eternally grateful !

With regard to my review yesterday May 16 2021 I felt the need to leave a review for the staff at Dr Diamonds also. When I first met them in 2015 I was greeted friendly and professionally. Being diagnosed with cancer, I was ofcourse overwhelmed. The Dr.s lovely Heidi greeted me. She spent time with me. Truly understood where I was mentally. I would say she was a determining factor in my accepting my condition and starting treatment. Trudy, who runs the office as far as setting up appointments and so many different hats that she wears, was warm, welcoming and so friendly. I always felt relaxed. My nurse Kathy is absolutely amazing. Kind, gentle, attentive. You couldn't ask for a better nurse. On a scale of 1 to 10 I'd like to give them a 12! As time went on, they became my family, Doc included. Couldn't have been sent to a better Oncologist and crew. Just needed to add these wonderful gals.

Dr. Diamond is aptly named because he truly is a gem! I have been seeing Dr. Diamond for over 10 years. He takes his time with every patient, so he always notices when something is not right. He is the most knowledgable and intelligent doctor I have ever met. He has literally saved my life, and I wish he could train other doctors in the right way to practice medicine; by treating every patient as a whole person who is important and counts.

I've been a patient for 25+ years. Dr. Diamond is extremely knowledgeable about the latest treatments for cancer. He's also kind & caring, takes time to answer questions, & makes sure his patients fully understand their diagnosis & treatment plan. Dr. Diamond's staff is also professional, efficient, & friendly.

Excellent physician and staff – Jul 11, 2019
×Post a ResponseAre you Dr. Diamond?
I have been seeing Dr. Diamond for over a year and he is an intelligent, competent and caring doctor. I wish I could clone him and his staff. At Dr. Diamond's office you are treated like patients, not cattle. It is comforting and refreshing to be welcomed by staff who actually know your name and why you are there. The way Dr. Diamond practices medicine and the way his staff runs the office is that of a bygone era. Having health issues is stressful enough, visiting your doctor shouldn't cause additional stress.

You may have to wait in his office awhile to see Dr. Diamond but it's because he never rushes his pts & spends as much time as they need with them. If you want an MD who sees you in 5 mins & rushes you out of his office this is not the MD for you. This man cares so much & is so kind. He's a very special MD-the kind that are very rare especially since Obamacare came into being. He literally saved my life & I hope he never retires.
