Dr. Konstantin was very helpful in expediting my U.S Coast Guard physical exam by writing two letters to the Coast Guard after they had rejected my physical application twice due to some medication I was taking. His credibility and expertise in these matters convinced the CG that I am fit for shipboard duties. His office is clean with the staff being very polite and efficient when I arrived for my physical exam and drug test. He has a good reputation which is evident by the traffic coming in and out the door. I recommend him to folks who need fast, fair-priced services. read more

I've been coming here since 2022. I love that you can just walk-in for your DOT physical and the cost of the physical is very affordable. Also, I have never had to wait too long to get seen. The staff are awesome. read more

I bring my boys here for their sports physicals and I think Dr. Konstantin is great. On a side note I came to this Yelp page to see what his rating was and human curiosity compelled me to read the bad reviews. I am happy to see that Dr. Konstantin is refusing to give random people narcotics. I worked in a 1000 Rx a day pharmacy and these people are doctor shoppers whose regular doctors won't give them narcotics so they seek out other doctors and then get disappointed and aggravated when they don't get their drugs. This makes me want to give Dr. K more stars! You don't go to a doctor to get drugs. You go to a doctor to get treated to feel better. It doesn't always require drugs, and you should be glad if you don't need them. read more

Been going for 10 years! Solid fast and efficient! Not cheapest in the world but honestly I rather pay for speed, quality and care- than stress out for days/hours and run through hoops. read more

Best place to get your Dot physical. Doctor and staff very friendly and professional, first place to give a medical card copied to fit in my wallet. Also nly 70 bucks really affordable and easy to get appointment read more

Always fast service and pleasant customer service. Dr. Konstantin is always ready and willing to help.

I used to h ave to wait weeks for an appointment at my old doctor's place! I don't care if I have to drive 30 miles to see these people! They are like Family!!!!! read more

Love coming to visit Dr Konstantin .. his office is ran very well ...the medical assistant are fast efficient and always in a good mood.. they go over and beyond to assist the patients... Dr Konstantin is a great doctor he's easy to talk to and always gives the best advice. read more

Best experience of a MD in my life. Thank you Dr John k. I would definitely would recommend.

I've been living in CA, USA for more then 6 years now, and had all kind of insurances and been to a variety of doctors & hospitals and I can definitely say - this is my best experience ever in the USA. The Doctor is so knowledgeable and attentive to the patient. It was NOT 3 min visit and 1 hour of waiting as I always have with others. Would 100% recommend read more

Dr.Konstantin is absolutely awesome, every time I have been in to see Dr. K. it's from an injury from Motocross racing career,back issue and he gets me going again with simple anecdotes and maybe a anti-inflammatory prescription and asks,"When is your next reace?",he's great,he doesn't try to get me to stop,he supports and that's a good thing,he knows there's no stopping a Life-long Motorcycle racer,but what he does is priceless. read more

I owe a big thank you for Doctor Konstantin. I really had a trouble gathering documents for my nursing school especially for the Tuberculosis, however Dr. Konstantin went a step forward to help me and provided me all the necessary documents for my school. I am very thankful and grateful for the big help :) read more

Love Dr. K, and his Staff!! Absolutely the best place to go for flu shots, TB, immunizations, etc. $40.00 office visits-CASH ONLY!! Great if you want to see a real doctor who is genuinely concerned, sits and talks to you and helps you understand the nature of your issue. Dr. K: Keep up the good work! We are lucky to have you! read more

Even after two years, I still think this place is great and I would hands down recommend this place to anyone living in the east bay. The only downside is that you might have to wait a little in the waiting room but it usually goes by fast. I come here for all my basic needs like vaccines and physicals. The MA's who work here have always been super sweet, friendly, and are willing to answer your questions to the best if their ability. read more

I have been seeing Dr Konstantin for two years. I have an excellent PPO but keep returning simply because he's a good doctor: 1. He spent several years as a researcher before taking over his dad's practice -- and you can feel it in the way he approaches problems. He knows his stuff and the theory behind it. 2. As a result, he can afford to be practical , non-dogmatic and very human. 3. I miss being told what to do by my doctor -- I don't want to be given a range of choices or hear that protocols require such treatment. And I certainly don't want to deal with the Nurse Practitioner if I pay the doctor's fees. I also want to face a figure of authority who knows better and be told what to do. That's what you get at Dr K. Dr Konstantin is my "no-BS" sounding board, an engaging man dedicated to a cause, a breath of fresh air in a medical world where it's easy to feel small and insignificant. read more

If I'm being honest, I'm not sure why this place has so many 5 star reviews. Only out of concern for public health, I am going to share my experience. I came here simply for a 2-step TB test that I have to get for a medical program. You can walk-in, no appt needed. It costs $30.00 initially, plus $10.00 for the second part. This part is all convenient and great. Let me start by saying that I work within the medical field, and therefore am aware of certain standards that need to be held in an office. Whoever did my first test (not sure if she is a nurse?), did not follow the correct protocol one should use in between patients. She called me into the room that was supposedly ready for me, but another patient was walking out of the same room simultaneously as I was walking in. Which means the room was not wiped down and not technically ready for me. As I was sitting in that room, she then, with bare hands and no gloves, ripped off the old paper on the medical chair that had been used with the last patient. Then she grabbed my materials to do my test next without washing her hands. And proceeded to do my test with her dirty hands and no gloves. She told me as long as I didn't see a bump for myself, I need not come in in two days to have them confirm a negative test. A week later, I came in for my second test. I mentioned to the woman who was doing my test this time, how the last woman hadn't washed her hands or used gloves after touching/cleaning up after the last patient. She nicely washed her hands, and then told me that she could wear gloves, but that the only size in the office was an extra large. This is because the actual doctor is the only one who wears gloves and he doesn't require the nurses (if they are even nurses), to wear them. So they only order any in his size. Aside from protocol issues, the actual office itself looks like a converted house, and the inside looks like an old run down veterinary office. I personally didn't feel like it was a clean environment that is safely practicing. This is why I find it hard to believe that basically every other review is 5 stars across the board. Something smells fishy. read more

Dude is seriously the best! Affordable, friendly, and your in&out quick. I live in Marin and come to this guy because I know I can be seen. I get my TB tests, and work physicals specifically here. Yes it's not the ritz and yes it's in East Oakland but he's worth the visit. Check him out y'all ! read more

This is the first doctor, specifically a general family practitioner, that our family has found since moving to the West Coast 4 years ago that Actually listens to and touches his patients and gets personally involved and cares... And when it comes to care, especially for my wife, that's all that matters to me. Awesome doctor. I've switched over as well... And yeah it's a 40 minute drive mid day from Napa to Oakland, but he's worth it, because our bodies are priceless and you only live once... And who doesn't like having an excuse to go shopping and grab a bite in Oakland whenever they get a chance on a nice day? read more

Dr. K is a solid guy, what can you say? You're in and out within an hour, meanwhile getting to chat with a man who feels like a family friend! He's jovial, engaging, and knows a heapin bundle about the digestive track, body breakdown and a bunch of other words I didn't quite know but MAN was it interesting! This is the only place I'll go for my regular medical needs- $50 in and out for a physical and I bet I coulda asked for a lollipop at the end, that's just the kinda man this Dr. K is! Staff is real friendly too. read more

I have full insurance coverage but was intrigued by the great Yelp reviews. I'm so glad I took my 4 year old daughter there! We walked in without appointment on Friday morning. Dr saw us quickly after filling out a simple form (took 2 mm vs the usual 20 anywhere else). He diagnosed us in 20 mm while being quiet but pleasant and giving us many medicine insight including out of pocket cost! How often does the doctor care about how much the medicine he prescribes is going to cost YOU?! Then we had to pay of course, and I was a little worried about ha ding out the $300 cash I brought. Doctor asked for a tiny fraction of that making me feel I was getting an absolute deal. Thank you so much Doctor for serving our community so well and faithfully, you simply took the financial worries out of my family getting sick. read more

I was referred to Dr. Konstantin from a mariner's school for a USCG physical - and now see why: he and his staff are efficient and friendly. Though walk-ins are common and available, I set an appointment and was seen as scheduled. Dr. Konstantin himself is easy-going, professional and genuine; not only checking off boxes, he casually asked questions and made recommendations ex. "Try to eat as naturally as possible; fruits, vegetables etc. Mix in some exercise and cardio." etc. Highly recommended. read more

Went in for a TB and Physical to fulfill a job requirement and BOY was it quick and easy. TB test ONLY: $20 Physical ONLY: $30 BOTH TB and Physical: $40. He honors appointments first but drop-ins are always welcome. I dropped-in around 10:30am and found that there were 3 patients ahead of me. I ended up getting out of the clinic within 30 mins which is crazy fast. When I got my physical done, it took like 5 minutes and he was thorough and friendly. He did not make it seem like he was superior or anything and the conversation was open and relaxed. I found out he went to UC DAVIS too (in the 70s...lol)! Parking: Pretty much just street parking (usually empty). There is one GREEN street parking spot right in front of the office (for quick visits/TB test readings). FYI: CASH ONLY! read more

Decent price without insurance, if you need a physical and TB it's quick and convenient

My wife and I moved down to Oakland a year ago. Neither of us has done the legwork to find a primary care physician that is in network with our insurance. I suddenly realized that my prescription for asthma medication had run out. I could have gone to an urgent care place, but probably would have walked away with a $400 bill that our insurance would have made us pay $200. It would have come out of our HRA/PSA, but I just didn't think that was a good use of money for such a simple request. I walked into Dr. Konstantin's office without an appointment, waited maybe 20 minutes, saw the Doctor and was in and out in less than 30 minutes from the time I opened the door into their waiting room. I am thinking this will be my go to solution if my wife and I have colds that won't go away or some other urgent care scenario where we can't wait to see a doctor. I had to pay $40 bucks out of pocket cash, but it was well worth the convenience. read more

I needed to get a TB shot for my new job, so I looked on Yelp and found this place. You can easily miss it driving by, it looks like a house, but there's a sign that indicates it's a clinic. I went around 10:30am. There were few people in the waiting room, but this nice nurse came in and said I was next the minute I sat down. I felt like she could read my mind it something. She had guessed I needed a TB shot lol. So she sat me down in this sterile room and had me filling out paperwork. When I was done, she quickly prepped my arm and grabbed the syringe. I have a phobia of needles and shots so in my mind I was preparing for the intense pain and quietly said a prayer as my braced myself. But you know what? I didn't feel a damn thing! I started laughing and the lady looked at me with interest as I told her my fear about needles and how I expected it to hurt. She just laughed and I kept thanking her for making my experience quick and painless. Make sure to have cash! It only cost me $20 which made me smile more. I highly recommend going here if you need any shots (be sure to check and see what they offer). Reasonably priced and great and quick service! read more

Great doctor for all your last minute medical needs no need to pull out your insurance card he takes cash on the spot and very reasonable and fair prices. read more

I came here because I don't have the greatest insurance coverage. I had baker's cyst which hurt a lot to the point where I could not walk. Other doctors were asking for $200 just for consultation and then $175 for the cortisone shot. Dr Konstantin gave me the shot for $10 and his fee was only $20. He is so sweet and absolutely amazing. He doesn't over charge as much as other doctors and also he doesn't try to gain a profit from shots and etc. Amazing doctor! Its mostly a walk in office and cash only. read more

I needed a TB test to work with kids and saw that he offered them pretty cheaply then found out that physicals were only a bit more, so I got one of them as well. Dr. Konstantin took time with me, was relaxed, and not hurried while speaking with me, which is what I would expect from a lower priced service. I have recommended him to friends. : ) read more

I got my TB test here as part of the clearance for OUSD. Was super fast and simple-- whole process took less than 5 minutes. When I went back a few days later for them to check my arm it was also super quick. The staff is really friendly. Tip: Remember to bring cash as they do not accept credit cards. read more

Dr. Konstantin is wonderful! Came here for a nasty bladder infection and left with a prescription to get rid of it. He is super personable and the visit was only $40! Which btw is less than the $60 copay I had for Kaiser back when I had insurance. The visit wasn't rushed and he made sure I was properly taken care of. My go to place now that I don't have insurance anymore. Also I noticed he treated all his other patients with the same kindness he had with me. Great place! read more

Incredibly cheap! $30 for a regular office visit. $40 for a TB and physical. I'm a full-time student on a tight budget, so he's currently my main source of health care. I've gotten my boyfriend to start seeing him too, which is great because he has always been reluctant to see a doctor due to lack of funds. Now he can get the medical attention he needs. Dr. Konstantin also does walk ins, and the wait usually isn't too bad. The longest I've been in the waiting room is 15 minutes. Other times it can be as a short as half a minute before he opens the door. No check in necessary. As for how the actual check ups go, my only complaint is that he does seem to be in a hurry a lot of the time. I'd imagine he's very busy, but nonetheless he gets the job done and is obviously well trained. read more

This has been my Physician for somewhere in the neighborhood of 12 plus years. The office staff is professional, with great bedside manners and phenomenal customer service .Dr. Konstantin is magical in his empathetic approach, combined with competence witnessed by his knowledge of current evidence based information that he has shared with me. Compassionate and understanding are just a few of the many qualities I found through my years of utilizing his services. He is very timely in getting back to you. read more

This doc is great. In and out in less than 10 minutes WITH NO APPOINTMENT! And guess what?! My pockets were pretty close to what they came in looking like! Got a physical and tb test for $40! I mean really?! Kaiser was charging me $200 for the physical and $75 for the TB(no coverage costs) he was nice and professional, clean and cozy office. And his mom was the receptionist the day I came in! I thought that was pretty awesome lo! I DEFINITELY recommend this doctor for your medical needs :) read more

I had a few doctors but no one compares to Dr Konstantin he is such a great doctor very easy going and he takes his time with you, And suggest options to help you out. He's a busy guy but he gets his job done efficiently. I appreciate all he has done for me. Definitely recommend him to anyone in the area. read more

Doctor is courteous, listens kindly and is practical. Location seems off the beaten path but it is easy to get to from the 580. House style office with availability as needed. Doctor takes walk ins and has been open to fitting me into his schedule on a Friday afternoon. He even returns calls! Excellent and fresh approach to taking care of patients. read more

That guy is amazing. His staff as friendly as can be and over all: pleasantly unburocratic. My daughter and I came in for a last minute physical for school. No appointment, almost no waiting time. Dr. Konstantin evaluated her quickly yet thoroughly and in this short time we laughed a lot. read more

I needed a TB test and called in beforehand to confirm whether they'd be able to do it (considering that Monday is labor day and you need the reading 48-72 hours after). Without even suggesting it, Dr. Konstantin offered to come in early to do the reading for me on an off day. It was so helpful because I'd like to get my hiring paperwork done as soon as possible. I appreciate it very much. The process for just a TB test was very quick! I left about 15 minutes after arriving. Walk-in, first-come first-served system. Payments are made in cash so call beforehand if you need to know how much to bring. It was $30 for the TB test. read more

Great Doctor! I've been in one minute clinic from CVS and they charge me 140$ and set wrong diagnosis. Hope this time will be better ))) I'm pretty sure that it would be. Doctor spend with you as much time as you need. Amazing Doctor, highly recommended! I just want to add, that the medication that he subscribe me helped!!! read more
