    Dr. Kramer is a superb Pulmonologist. PERIOD. My brother, who is also her patient, and has had more…read moreinteraction than I, considers her as more than an excellent clinician... a kind, considerate healer. Last year, I posted a review complementary of Dr Kramer's reputation, but critical of the unnecessarily and surprisingly rude treatment I received from one of her staff members in the process of obtaining my initial consultation with the doctor. Now, seven months later, I have received a reprimand from Yelp stating that "We ask that reviewers avoid commentary that reinforces stereotypes, makes light of physical or sexual violence, or otherwise includes unnecessarily graphic or offensive descriptions. In this case, we felt that your content crossed that line, even if you didn't intend it to." Of course, NONE OF THAT IS REMOTELY TRUE!! NONE! I have no qualms about my original post being deleted by Yelp. But I do object to untrue allegations towards me or anyone else. To be clear in the distinction here, Dr. Kramer is excellent, my experience with her has been excellent and I unhesitantly recommend her. In the course of ordinary living, I experience rudeness frequently but that would not ordinarily cause me to write a negative review about it. The rudeness of this one individual was unnecessary and memorable, so I did post a review about it. Moving to the present and to the credit of Dr. Kramer's office and staff, I could not have been treated more kindly during my actual office visit interactions. So kudos to all in that regard.

    I have personally seen and experienced how great of a physician she is! Not only is she very…read moreknowledgeable and skilled, but she possesses deep and genuine empathy for her patients and their families. She is very approachable and honest and handles very stressful situations well. I highly recommend her for her remarkable intellect that is backed up by years of experience, but more for her caring heart.

    I too have recently experience:…read more 1. What Amy stated in her review, "It's been nearly impossible to get in touch with anyone there. They don't answer the phone, and even though some extensions allow you to leave a message, they never call back. This lack of communication is incredibly frustrating and unacceptable for a medical practice." The Diablo Pulmonary Medical Group staff does not even reply to MyChart messages. 2. What Felipe P. stated in their review, "Just got a bill from January, and nobody in billing answers. Called 3 times, left 3 messages and no response." When you call the office there is an option for Billing, which is use less, always received a recording to leave a message. This option and personnel need to be removed because they NEVER return a call. I even called at least three times and selected the option to schedule an appointment for I have had better luck some one answering. I asked the person who answered if the billing person was in (Sarah?), and of course she replied "No, but I can take a message." (Do not know what she did with the message for I never receive a call back.) I informed her I have left several messages via the Billing option and have never received a call back. What a plush job Sarah has.

She was pretty dismissive, chalking it up to asthma or long covid and referred me to another doctor to get a breathing test which I was hoping to get here (these are things my PCP already suggested which is why i was referred here in the first place). The appointment lasted less than 10 minutes. On top of that, they told me to email my insurance information to them, to an email account which doesn't exist (the email bounced back to me) and like everyone else is saying, they do not respond to calls or emails regarding billing. I have reached out multiple times and cannot get in contact with anyone. Won't be going back

His location is convenient and his staff cordial when you meet them in person. However, trying to reach his office for an appointment can be quite a challenge. The phone prompts are endless and usually no one answers and you have to leave a message. " To state "Please listen because our numbers have changed" is trite and useless". Every doctor's and business'es phone prompt says the same thing. Just get on with what the numbers represent. It is all very frustrating;to my brother in law because his MS. does not permit him to use a computer. Therefore the MUIR website is not useful. He must rely on the telephone because he also has impaired vision and cannot read his mail. . However, telephone communication issues are not just Dr. Hadley's. It's the same with all of our local doctors. Phone prompts and staff communications are generally very time consuming and frustrating. When I was a young boy My mother would call and my doctor would come to my house to treat me the same day or evening. He drove a Chevrolet or maybe a Buick. Now I cannot reach my doctor and he drives a Mercedes Benz and is shielded from communication through his office staff and billing contractors.

I was able to pick up the at home sleep study test kit in a few days, and the in-office instructions on set-up and use were decent enough once I supplemented that with a quick YouTube online search on proper use for a successful test and data entry into the equipment. But then the wheels came off! I dropped the kit off to Dr. Nathan's office as promised the very next morning before 11 AM. I was told that due to the holidays, it would Nathan up to two weeks to view the data and write the report of my sleep study to my John Muir primary care doctor. I was told that the study and the data held in the device was quite good and I could expect the report in due course and timely. It has now been three weeks since the device was returned and the data entered into Dr. Nathan's office based system, but I have no report whatsoever, no response to my inquiries, and even telephone calls from my primary care doctor to Dr. Nathan (that apparently owns a financial interest in this sleep clinic) have been totally ignored. There is no justifiable reason why Dr. Nathan should take three weeks to compile what is almost certainly a machine-based standard report based on the electronic data downloaded from the sleep study device. The delay is bad enough, but being completely ignored is perplexing and very disappointing. I will not return to this clinic and I would not recommend it based on my experience over these last three weeks.

He has been thorough in answering all the questions I asked him during my appointment visits to the clinic.

In this regard, I would like to highlight his staff member Giana Acosta, who has exemplified great professionalism and excellent support service in all her interaction with me on the telephone as well as in person during my appointment visits at the clinic.

    This is for the In person sleep study I did last week…read more I recieved a phone call asking if I'd like to come in at 9:45 instead of 9 am. I said that would be okay. I get there at 9:30 and fill out my paperwork. They sent paperwork to my email but I had already filled the same paperwork out when I came in office so I didn't think I had to do it again. I did. It did not take long. My technician was a man named Jerimaih. I think that was his name or Johnathan. I'm sorry I'm so bad with names! He was very nice. Coming into the building was creepy lol You put a code in and go upstairs or take the elevator. Walk all the way down the hallways to the left. When I was done filling out paperwork another lady came in saying her appointment was at 9:45 and Jerimaih let her know I was his 9:45. He told her that her appointment was at 9 and she proceeded to go back and forth saying she has a voicemail saying they changed her time. Never played it but kept saying she had it. Then said she didn't know if she deleted it. I told him someone had called and left me a voicemail asking me to call them back. My appointment was originally at 9 pm and they asked me if I would change the time to a later time. Before we went into the room he asked if I needed to use the bathroom. Then explained how he was going to hook up the wires to my chest, neck, head, face, bottom of my legs. I thought he said feet but nothing was placed on my feet. It sucked bad having all of that attached to me. He was polite. They add straps around your chest and stomach. There's a camera in the room. Nothings on the room except a chair, table, bed, camera watching you and the bed. I had a hard time sleeping. I toss and turn a lot and it was hard with the wires added to me. I kept waking up, woke up coughing. They wake up up at 5:15 I think.but I already woke up at 4:50 and sat up. Jerimaih came into the room asking me if I was okay. Which I stated I was. I get pains in my legs and arms at night and just explained that and I wake up constantly throughout the night. He said he would stop the study and come back to unhook me. Once unhooked they have you sign a paper stating you are awake and alert to drive him. He also explained the dr will look over the test and they will call me back in for the Cpap machine if they decided I need it. I actually do. I was told by the dr in the concord location many years ago that I did have sleep apnea but I never came back for the sleep test. I did the two day home study which they did not get anything from because the thing flew off my finger. That's why they had to do the in person study. Jerimaih had to tape the thing that goes over your finger to my hand because I told him the last one ended up on the floor! When you go to the study it's going to be uncomfortable having all of those things attached to you. The next day you will feel sticky on your head, neck, face from the stuff they stick to you. I felt like I was scrubbing forever to get it off. I would definitely recommend them. I see all the bad reviews and I'm sorry those people had bad experiences but mine is always pleasant when I come here. Hopefully I get my machine because my neurologist said it would help out a lot. Not sure how much data they collected. I feel like I had a hard time sleeping from tossing and turning and waking up coughing.

After wanting a second non-Kaiser opinion on my thyroid and having issues setting up an appointment online, I called and scheduled a video consult. The pre-paperwork was a bit lengthy and during our appointment we went over my story. While I was able to confirm with her that my current medication was the best course of action, I didn't love that I later met with a Kaiser doctor who provided me with documentation that hypothyroid patients can have nasal nerves that go, for lack of a better word, haywire (falls under the term non-allergic rhinitis) and that lowering my dose as she suggested might actually cause the nerve to flare up. Overall I felt like One Medical had a better intake that was more thorough and helpful, and John Muir Allergy was overall more knowledgeable. At the end of the day, the out of pocket cost for the appointment was around $240, and I essentially got what I was looking for which was a discussion about my medication but I don't plan to move forward with Jiva Health.
