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.

Outstanding!! Enough said.

I saw him in an emergency situation and he was quick, knowledgeable and took most excellent care of my problem. He is the very best cardiologist I had so far.

Amazing and caring specialist
Dr Altman always goes above and beyond. He’s very smart and very astute with understanding what’s going on. He has been helping my Mom for the year and has really helped us with understanding her condition and trying to keep her healthy and happy. He’s really an impeccable doctor and we are restful for his care and professionalism. Highly recommend!

I was his patient from 2011 to 2022.
I first met Dr. Altman from an ER visit. I had a cardiac event requiring 3 stents. I showed up at the ER at 1AM, I was tested, diagnosed, and in the Cath Lab by 4AM. I was impressed at his ability and professionalism. He was my go-to Cardiologist after that. Dr. Altman has a GREAT bedside manner. I always felt special when he was seeing me. He always knew what to do next to keep me alive and well. I never had a problem booking visits. His staff was always helpful. Stress tests and other tests were booked in a reasonable time frame. I moved out of the area in 2022 and I'm sad that I had to leave his care in 2022 as I moved to the east coast to retire.

Great Care!
Dr. Altman did a wonderful job with my cardiac catheterization. He provided precise understandable, complex information beautifully. He was kind and supportive that I would be able to live many more years. Terrific physician!

He isn't the only one I've been too but definitely one of the best. He goes above and beyond as far as explaining procedures and making the patient the most comfortable as can be expected. I put my trust into his amazing ability to save lives as he did mine. I've been to him a few times and definitely would again. So glad Dr. BUI sent me to him.

Dr Altman treated me Friday August 16 2019. I was being seen for a heart kath. He and his staff were great, they helped turn a very stressful situation into something more manageable. His staff was very good, always explaining everything. Dr Altman himself was very knowledgeable and explained everything. I was lucky my procedure turned out great. But I knew he take care of whatever came up Thank all of you again, I would highly recommend you to anyone.

I’ve been pleased with my two meetings with Dr. Altman in the past year, although I waited 45 minutes past my last appointment time. However I may decide to go elsewhere because I can’t reach the office by phone. I tried 5 times to call to change an appointment, waited on hold an average of 15 or 20 minutes and never reached a human being. So I’m a no show. That’s just wrong!

Recommending Dr. Altman and CHV has dropped from "definitely" to "maybe" due to the office being overwhelmed. Plan on waiting each and everytime you have an appointment. A 2:00 appointment might be 3:30, a 1:00 is 1:45... they have never been even close to meeting a appointment. It's only a time for you to show up, not for them the meet you. Your time is irrelevant. I can't imagine ANY other business surviving with this customer last attitude.
