Dr D is a fantastic. I've been going to him for help for almost 20 years. He is very well seasoned and has seen everything. He is young and active, not like many of the older Dr's that seemed to be out of shape, out of touch and not in the same reality that I live/work/play in. read more

It's tough to find a good doctor. I changed insurance and had no idea where to start. My company has people who help us find good doctors, and Dr. DeLange was recommended. The ladies at check-in were super nice, and answered all my questions. Dr. DeLange listened to my issues and referred me to some good doctors. He took the time to make sure everything was addressed. The ladies at the desk scheduled me for a follow-up appointment. It's good to know there are doctors out there who care. This man is one of them. read more

About a week or so ago I took my 88 yr old mom to see him because her regular doc was off. She has survived lung cancer twice and has a JaK2 mutation of her blood. HUGE mistake. The minute she gave her symptoms all he thought of was covid and berated her for coming in. He didnt listen to her heart and lungs or much of anything else. Looked up old labs and said she had been anemic. He didn't order new labs. Treat the symptoms is all he said..might be a virus and they last about 10 days. She had already been ill for longer then that. 2 days ago I went to another doc cause she wasn't getting better. There we find out she has a MAJOR heart murmer. Labs were ordered and the blood is out of wack. They. did a CT only to find 2 spots in her lung ...one on her spleen . Tomorrow she goes for an echo of her heart and a petscan. Which doctor do you want..one that does nothing and exponentially increases the odds that you die and suffer or one that takes action and treats their patient like they matter. Save your life or that of your loved one and go elsewhere! read more

I read some of the reviews and I don't really get it. The fact is some of them made me nervous, but those concerns were unfounded. I arrived early for my 1:45 appointment... maybe 1/2 hour early. I was surprised to find the door to the office locked. I was very concerned and nervous, but someone quickly came to open the door. Given I was early and it was around lunch time, they probably locked up for a lunch break. The staff were all very friendly and professional. And Dr. Delange couldn't have been nicer. He really took time to get to know me (it was my first visit) Even thought he had to document on his computer, he talked to me. We had a real conversation. He seems very genuine. I'm excited to be a patient of Dr. Delange. I think it's going to be a great relationship not just with him, but with his staff. As a quick aside, when I see a new physician, I'm there to interview them, in a sense. I need to feel comfortable and confident. I was. For anyone looking for a physician in Hayward, I recommend Dr. Delange. read more

Great Doctor. On my 1st visit, we talked about my general health, and I was surprised to find that he had my medical history, and had obviously read it. He's Professional, courteous, knowledgeable, and efficient. And so is his office staff. Dr. DeLange is the best Doctor I've had in years. Highly recommended. read more

Very rude. Called to schedule a refill for my grandfather and was laughed at over phone because "it is not possible for his meds to be empty". I was asked why has he not called to schedule a refill, I guess his records do not state that he is 97 years old and hard hearing. read more

Every single time I call, the staff is friendly and books me an appointment right away. The nurse practitioner is out of this world and really cares about the patients. She does not rush you while in your appointment and takes the time to listen to each concern. I highly recommend this practice. read more

My first encounter with Dr De Lange's office wasn't the best. I tried to call and get an appointment as he was my assigned dr, but I had never seen him before. I had a feeling I had a kidney infection and was in a lot of pain with a very high fever. I called and asked to be seen he said he was full and couldn't get me in that I should go to urgent care the next day, so I spent the whole night in excruciating pain then went to the urgent care facility they told me to go to. I went in as soon as they opened and they couldn't see me because Dr. De Lange wouldn't approve it, I got on the phone with him and he said there was a miscommunication to please come into his office. I went straight there and he has been amazing ever since. That day he didn't find a kidney infection but gave me antibiotics that day while he ran more test and gave me pills to relieve some of the pain while they figured it out. He was amazing that day and I seen him for years until I lost my insurance. 3 years ago after I lost my insurance my son desperately needed a physical to get him into school, Dr. De Lange seen me and my son with no problem and no insurance. We were in and out and my son started school on time. I also went to him 2 years ago after I was in a car accident and he was very helpful on helping me understand all the repercussions of the crash, how the little bit of pain I was feeling now was only the beginning of the pain I would feel. I was still in shock and my whole body would hurt by the end of the night. In short he is absolutely amazing and has always been so helpful to my family. His front desk staff is so sweet and amazing to. They make you feel so welcome every time you come in. read more

Save yourself the time, this physician is really not someone who is qualified to care for you or your loved ones. He is not current with medical research & practices, as such, wastes precious time pursuing incorrect costly, antiquated diagnostic procedures and outdated medication trials. Additionally, this medical provider is not caring or compassionate, when valid concerns were brought to his attention, he refused to address these concerns (his poor judgement and proceeding errors) without additional office visits $$$. I'm so disappointed to see a medical "professional" behave in such a money-focused manner, forgetting that he's treating human being and the additional concern originated from an error due to his lack of knowledge on current trends in medicine and reliable diagnostic tools. So unfortunate. read more

Dr. DeLang is one of the most authentic trustworthy doctors, I've ever had the pleasure of working with. I've been going here since I moved from the east coast (1998) and he, nor his staff have ever fallen short to provide me with the utmost caring professional services I deserve. I Highly recommend this office to all of my friends and family!! The front desk ladies are extremely friendly and talkative every time I go in !! Also, The new physician assistant I met today, (sorry, I totally forgot her name) but she went to SMU...she is so sweet, a great listener, and explains questions. I honestly look forward to my next doctors visit so I can chat with her again!! Thanks, Dr. Delang and his staff!!! read more

I've been going here for a few years and Dr DeLange is a great person but lately I've been getting the run around I do believe at this point I will be looking for a new Dr. read more

I'm a new patient but have been looking for a reliable doc in Hayward for four years now. i really love Dr. Delange very professional. he listens and is very articulate, and the place was nice (not ghetto). i hope to stay with him for many years to come. read more

I've been seeing Dr. De Lange for over 30 years and he is a great family GP. He has done an excellent job managing my health over the years, especially as I am getting older now. He is very attentive and easy to talk with, and most importantly has very good medical acumen. He is also very up-to-date with the latest information technology tools in helping patients manage their health. Thank you Dr. Lange! read more

After 44 years of going to Dr Crocket and Dr Delange they now long will except Anthem Blue Cross , WTF this is a clinics decision very sad I have to find a new doctor! Always about the mighty dollar read more

He was a family doctor but no longer. Went to see him for strep throat with my throat closing and he prescribed me antibiotics but no pain pills. Antibiotics weren't working so I called him for a new prescription got the the run around for two days and finally 5:04 get a call back sent me new antibiotics but refused to send me pain meds when I told him what I was taking doesn't work. Tells me to keep taking them they aren't working now what makes you think that's going to change! Sent my prescription to the wrong pharmacy I realized as soon as I hung up and now because it's after 5 it's after 5 they refuse to answer the phone.(even though I literally just got off the phone with the girl) So now I have to wait until tomorrow to have them sent the correct place. Office sure has went down hill. I guess they don't realize the pain that comes with strep throat I can't eat and haven't in two day because of the pain and they refusing me pain meds for no reason. What kind of doctor knowingly let their patient be in pain I will be finding a new doctor. read more

We love Dr. DeLange. We have been with him since he took over from Dr. Crockett. My husband has diabetes and irregular heartbeat, so he has lots of problems and Dr. DeLange is always there to help him out. Very professional and knowledgeable and has a great "bedside" manner read more
