In my opinion, this institution is a huge setback to our area. They seem to be more concerned with…read moretheir own interests than the people they "serve". I have tried for over a month to contact patient relations. I got one call back from "Ashley". I called back leaving messages to call back, but now for over a month, they have seemingly deliberately ignored my requests. I put another call in to the main 3333 number to make a fresh request. The person answering clearly knew who I was and what the situation I was calling about was. I was assured I would be called back, but as of one week I have heard nothing. In general, I hear many people say that the doctors there generally don't really care about their patients, that they are arrogant, and don't communicate well. There is much more that i could say, but i will say that a large majority of the staff, are genuine people from our area, and do their job well, but the medical providers are the main problem that i have noticed and heard complaints about. There are definitely some good doctors, but they apper the exception not the rule. i only have experience with certain providers. Some are great some not at all. I do hear feed back from a number of people i know who feel similarly. One other important observation is that when you rate a Stanford doctor highly, they give you a rating questionnaire AFTER EVERY VISIT. Once you give a bad rating, say because you learned that an "excellent " physician was actually a "fair weather friend" and suddenly wasn't so good at all if things got challenging, then they seem to stop asking for evaluations. You will notice that their physicians public individual ratings are based on internal surveys, and it is difficult to find a way to rate the physician outside of their internal system, thus likely artificially boosting their ratings by limiting the negative ratings...

If you are a WOC with break through pain from chronic pain cluster headaches, hemiplegic migraines,…read moreand trigeminal neuralgia/ atypical facial pain...if you choose standards ED proceed with caution. IKYKY Came to the ED for a really bad cluster headache and trigeminal neuralgia attack. Feel free to look up the nicknames for those illnesses. When getting treatment, a PA made sure to tell me he doesn't prescribe narcotics, which was odd because that would actually make my pain worse and I'm allergic to them. The comment came unprompted when I was crying and the nurse trying to start an IV. They gave me fluids and migraine cocktail despite telling them it won't work. The treatment finishes, and as expected it didn't work. I eventually get to the observation unit, not technically admitted but there to get some imaging. They give me IV Tylenol, after telling me that I might have a Tylenol overuse headache along with more fluids. I got Ativan for an MRI, had the scan, and then go to bed around midnight. I wake up 3 hours later in excruciating pain and used the call butting to ask for pain relief. They bring me both ice and a hot pack. When the nurse came I did my best to not cry, only because it would have increased my pain, and hugged a pillow while they gave me the packs. 2 hours passed and I'm sobbing and absolutely inconsolable. This pain was past the 10/10 limit on the pain scale. I was in so much pain to the point my mental health was becoming compromised. I rang the call button through out the night and was only given heat packs. Hours passed in a pure state of paralyzing pain until around 9-10AM when a nurse came in to check on me. I was just crying, not able to do anything but just curl up in a ball and wanted to just go home and be with my pets if I was just going to suffer. I came here because UCSF ran out of answers on what they can do to help me very treatment resistant pain. They eventually give me more Ativan to stop me from crying and then left me alone in my room still in excruciating pain. Around noon I had finally gotten highflow oxygen, which I learned at the time was the tip treatment for cluster headaches. I waited in so much and felt so vulnerable and minimized with how I was treated. They were happy to use Ativan to stop me from crying from pain because I guess it's annoying, than to actually treat conditions called the suic*de headache/ disease and help me get to a pain level that is bearable. The neurologist that saw me gave me the "I'm sorry this is happening" and refused to write an RX because I didn't qualify due to me not having respiratory issues despite oxygen being the recommended treatment for my cluster headaches. They recommended that I come back every time for O2 for my cluster headaches instead of having a home treatment. This experience was definitely a learning moment, I didn't get this type of treatment that had such contempt for chronic pain patients when I lived in Oakland and went to Highland. I left feeling like I should have never came to the ER and should have dealt with this by my self at home, no matter how bad it gets. I guess the silver lining is that they were less condescending than UCSF, I guess. The only reason why I would come back is because my options are limited on where I can go.

I can't recommend Dr. Mielke highly enough. I've been her patient for over seven years, and…read morethroughout that time she has consistently provided exceptional care. She is incredibly knowledgeable, thoughtful, and truly takes the time to understand the whole person rather than simply treating symptoms. I have always felt heard, respected, and actively involved in every decision about my care. What truly sets Dr. Mielke apart is her dedication to staying at the forefront of medical research. She is always up to date with the latest scientific findings and evolving approaches to patient care, and she thoughtfully incorporates that knowledge into personalized treatment plans. It gives me tremendous confidence knowing that my care is both evidence-based and tailored to my individual needs. She explains complex medical topics clearly, never rushes appointments, and genuinely cares about helping her patients achieve the best possible health outcomes. The entire team at Optimal Spectrum is also professional, responsive, and welcoming, making every interaction a positive experience. After more than seven years under Dr. Mielke's care, I can confidently say she has exceeded my expectations in every way. If you're looking for a physician who is compassionate, exceptionally skilled, and committed to providing the highest standard of modern, evidence-based care, I wholeheartedly recommend Dr. Mielke.

She expertly put me on a regimen of non-toxic compounds that she adjusts every quarter based upon her indefatigable updating of the advanced science on which she relies. She is both caring and direct. I credit her with much understanding and support and, essentially, keeping me alive while I avoided toxic recommendations from my more traditional team. The complexity of Dr. Mielke's patients means that while she has a killer memory and excellent medical training plus nearly a quarter century of running her clinic, she simply cannot know everything that will ultimately be the key to a particular individual recovery.

In one instance, I was waiting for interpretation of important test results related to my health. Instead of receiving an explanation of the results and guidance on next steps, I was told to contact another department myself. Patients should not have to act as intermediaries between Kaiser providers and departments to get answers about tests that Kaiser ordered. In another instance, I sent a message to my primary care physician and received a response from a nurse stating that the doctor was out of the office and that if I wanted an answer, I should resend my message after the doctor returned. I found this completely unreasonable. Why is it the patient's responsibility to keep resending the same message until it happens to reach a doctor at the right time? Messages should either be held for the physician upon return or routed appropriately within the care team. The recurring issue is a lack of ownership. Ordering tests is only part of patient care. Following up with results, explaining what they mean, and providing next steps are equally important. Patients should not have to repeatedly chase down information or navigate internal communication gaps on their own. I expect better coordination and accountability from a healthcare organization of this size.
