    Which hospital is he affiliated to?

    He works with Palo Alto Medical Foundation, which is a Sutter facility. He sent us to Stanford for my daughter's open heart surgery.

It makes life easier to have all of your doctors know each other and be friendly colleagues so that they all communicate with each other for a smooth care plan for you. Her tremendous knowledge of cardiology pairs well with her care and love for her patients. Dr. Madala makes my comfort and well being a priority. I have seen her move mountains to present to the board of my insurance company to convince them that I need the rx for my health. If being the kindest and sweetest human being is not enough, her love and compassion for her patients will convince you. I refer everyone I know to her. I am very proud of her. I sent my husband to be cared by her as well. I want my husband to be around a very long time. Her entire office goes above and beyond in a genuine way. Alex is the cardiac ultrasound tech. He is amazing as well. I leave this review with much pride. A little helpful note*** Her new office is on Winchester in a beautiful area of LG. This building better suits her.

Dr. Madala takes the time to really listen to concerns, explains test results and treatment options clearly, and never makes you feel rushed. Her calm and thoughtful approach immediately puts you at ease, even when discussing serious heart-related issues. I truly appreciate how thorough and proactive she is in managing my care. The office staff is also courteous and efficient, making scheduling and follow-ups smooth and stress-free. If you're looking for a cardiologist who combines expertise, compassion, and clear communication, I highly recommend Dr. Durga Madala.

I am a scientist myself and a philosopher - in fact I had written a book chapter in which I describe response of cells to nutrients and I highlight my logic on responses of cells to low as well as high doses and there is a plateau which is the optimal range - the length and width of this optimal range can vary with different cells and for different nutrients, but as much as high is dangerous and low can also be dangerous. I would like to refer to a 2025 peer reviewed article in Lipids in Health and Disease -Title Emerging risks of lipid-lowering therapy and low LDL levels: implications for eye, brain and new onset diabetes - the crux of this article states " their findings highlight the need to reassess the "LOWER IS BETTER" paradigm. and it goes onto say there is urgent NEED to establish SAFE Lipid thresholds and optimize therapeutic strategies" - I would like the other cardiologists to comment on this. If I were to draw an analogy, it is like if a human has a skin disease, to dip the patient in aqua regia - yes it will cure the patient but it will also kill the patient!!

    A Well-Oiled Office…read more.... Pros: People are top of the line. Good location and parking. Cons: Waiting room is often crowded. Office interiors are a bit frayed. Suggestion: Patients - Be flexible with your schedule. Dr and Staff - Declutter the office and give it a fresh coat of paint. Star Ratings: - Overall: 4 - Scheduling: 5 - Waiting for Appts: 4 - Location: 4 - Waiting Room: 3 - Wait Time: 4 - Technicians: 5 - Dr Hirschfeld: 5 - Office Environment: 3 - Billing: 4 - Parking: 4 - Restrooms: 3 ( needs more cleanup ) It's probably just a sign of age. When you're 11, you go to the orthodontist for braces. When you're 61, you go to the dermatologist, gastroenterologist, internist, opthamologist, podiatrist, rheumatologist and, of course, the urologist...not to mention the chiropractor, physical therapist and dentist ( if you have any teeth left ). So it came as little surprise I needed to see the cardiologist. When I first noticed some scary symptoms in 2009, such as chest pain, my primary care physician heartily recommended me to Dr Hirschfeld. A series of tests at that time revealed no problem, but when similar problems occurred recently, I made a fast dash ( maybe a brisk walk ) back to his office. - Scheduling: The calendar belongs to Patty, Dr Hirschfeld's receptionist. She's very good at juggling appointments which is necessary since the caseload seems quite high and the wait for non-emergency procedures is rather long. - Waiting For Appointments: Depends on the severity of your situation. My initial "stress test" was scheduled within a week of a request, possibly because it came from my doctor. Something was a bit suspicious, but the follow-up "stress echo" took 3 weeks to get on the calendar. Your flexibility in hour of arrival will also be rewarded. My job limited appointments to the afternoon. - Location: In a "relatively new" building at the west end of the Good Samaritan campus. 15 years isn't new, but compared to 40 in the main hospital it is. Good access to nearby roads. - Waiting Room: Fairly small, especially for the number of patients seen by the 3 doctors who share the facility. There are many magazines to read, but you might do so standing up or elbow-to-elbow with a neighboring chair. - Wait Time: Not too bad, considering the high volume of patients. Apart from completing any paperwork, plan to sit for 5-15 minutes. - Assistants and Technicians: Everyone I met seemed conscientious, friendly, knowledgeable and understanding of pain which is particularly important as the treadmill accelerates and incline is raised until your face turns red. Once your blood pressure reaches a certain level and you're about to "cry uncle", they'll help you recover at your own pace. - Dr Hirschfeld: For a guy with seniority in the profession, he's surprisingly energetic and highly involved. On both occasions, he answered all my questions and made time to double-check the symptoms. That's in contrast to my experience in 2009 when I feel he didn't take my issues seriously. - Office Environment: About as you'd expect...busy, a bit cluttered and shopworn around the edges after many years in the same location. - Billing: Efficient. They get your insurance information up front and paperwork is handled behind the scenes where it belongs. I've only to cover a co-pay at each appointment. - Parking: Plenty in a parking structure to the north plus scattered spaces to the east toward Good Samaritan and the older, single floor medical offices. Overall, I'd recommend Dr Hirschfeld and his staff. It's like a well-oiled machine... although a bit overworked.

    I can't recommend this office enough! Compassionate and…read morethorough..you couldn't be in better hands. They don't make them like this any more. Dr Hirschfeld I thank you and your office.

I was very impressed with the quality of care that I received - starting with a thorough ultrasound and explanation of feeder veins that first needed to be addressed. Dr. Fattahi and his entire team are patient, and very calming - which is a huge benefit during this type of procedure. They also explain what's happening and what to expect, which I really appreciated. In addition, the cost structure is clear - which was NOT the case when I was first exploring other doctors. I definitely recommend Dr. Fattahi and his team and I won't hesitate to return if/when necessary down the road.

After years of dealing with worsening vein issues, I finally found a medical team that took my concerns seriously. Why this clinic stands out: As a former athlete, I was frequently told by other doctors that because I was "young and healthy," my vein issues weren't a big deal. Dr. Fattahi was the first to actually validate my concerns rather than rushing me out the door. Instead of just looking at the surface, Dr. Fattahi explained the underlying issues causing the varicose veins. He used clear visuals and data to show me how the condition could progress if left untreated. The focus wasn't just on aesthetics (though the results are incredible); it was about fixing the functional problem. He broke down the entire process so I felt confident and informed every step of the way. The Results: I've attached my before and after photos (after photos are in the blue shorts). The physical transformation is obvious, but the relief from the discomfort and the peace of mind knowing the problem is solved is the real win. If you are experiencing any varicose vein issues--especially if you've felt dismissed by other providers because of your age or fitness level--do yourself a favor and book a consultation here.
