Shawn Hassler, MD

My second Unilocal review! I’m selective with what businesses and service providers I will genuinely recommend, but this office is just fantastic. They are responsive, knowledgable and I appreciate that Dr Hassler and the other practitioners I’ve seen there will patiently sit there for as long as necessary and answer every silly question I have.
The folks at the front desk go over and above to help out and are incredibly friendly and easy to schedule with. I’m really happy I found Dr. Hassler and appreciate the great experience I’ve had with him and his team.

Dr. Hassler is the best doctor I’ve ever had. He looks out for me in ways that take into account my lifestyle and family history. He is personable and has a great staff. I highly recommend him.

I’ve had the best experience with Dr. Hassler’s office. I’ve only worked with his Physician’s Assistant, Aaron McCloud, yet I’m more than satisified. I usually experience doctor’s trying to get me out of their office as quickly as possible to make room for other patients but with Dr. Hassler, I’ve never felt unnoticed. They always make sure that I have everything taken care of and that I’m perfectly satisfied and they’re genuinely attentive and seem to truly care about their patient’s well-​being.
Superb! I’m almost afraid to post this so I can keep this great secret all to myself.

I wanted to add that in addition to Hassler, Dr. Aaron McCloud is an amazing doctor. I have the unfortunate circumstance that I must move and find a new doctor in my new area. They will hard to replace. I sure wish I could take these guys with me. If you have the opportunity to choose this practice you won’t regret it.

I literally laughed out loud when one of the reviewers recommended Martin Mass over Shawn Hassler. Really? Dr Mass, while knowledgeable, needs to retire. I left him for Hassler because Mass had the personality of a rock. Hassler can be stern, but he’s a great doctor. If you need coddling, then you should see his physician assistant Aaron McCloud, who is very sweet (and quite hot!).

Being a Los Angeles transplant, I am accustomed to the world class medical care that I was provided by my doctors at Cedars Sinai.
Dr. Hassler is an amazing doctor that provides service at that same high end level. He is empathetic, genuine, and completely professional. What I really enjoyed about my visit is that he takes a holistic approach when it comes to health care. I made an appointment for my annual physical, and he made sure to address everything from my work life balance to my diet and exercise regimen. Not only did he inquire about my my physical ailments, but he also took the time to address psychiatric issues as well. What I really like about him is that he is a hip doctor. I was able to be completely honest about my personal life and habits without feeling like I was being judged. He asked me relevant questions and listened to my concerns about everything from fluoride in toothpaste to needing to be sedated while flying all without making me feel like a nutcase. Best of all, he spent the full duration of our appointment getting to know me and my medical history. He asked me so many questions, you can tell that he genuinely enjoys his profession.
Dr. Hassler is an amazing addition to Bay Area community, and as a queer woman I proudly endorse and support his practice.

Dr. Hassler is great but his office is poorly run and customer service is a low priority. Three days since the pharmacy called his office to confirm a refill and no response. Unfortunately this is typical. There have been multiple issues with communications from his office over the past couple of years. I tried to express my frustration with his staff and they had no time or desire to have a that conversation. I am switching to a physician office that has better operational practices.

I was referred to Optimus by my colorectal doctor and they’re now my main go to. I’ve only worked with Greg but I always have an excellent experience and they’re completely professional.
I highly recommend them.

I have been to Dr Hassler four or five times now and I am extremely impressed with his professionalism and expertise. He knows his stuff and he gives his time to each patient as they need him. We need more doctors like him.

I hate to differ and don’t like to disrespect doctors who work with our community, especially HIV. But Hassler is a complete dick. His staff are wonderful, but I was in a very difficult situation with insurance right afte seroconvering and got no help at all. He told me to just contact the manufacturers of meds once he found out. I was real lifestyle issues he didn’t approve of and i felt he completely lost interest in my health or guiding me to solutions.
Go to Gary Feldman or Martin Mass for HIv Care. Hassler gets attention, but if you have complications — he’s not there at all. He really sucked.

My Doctor Is The Best What More Can I say

I have been going to this office for over a year, and I have never been disappointed with the amazing quality of care and compassion here. Dr. Hassler and his physician’s assistant Greg Sauers have both been very helpful to me, or have referred me to needed resources that could. If you’re in San Francisco and in need of a new primary care physician, this is the first and only place you need to look.

I absolutely adore Greg Sauers, he is wonderful!

I have been a long time patient of Dr. Hassler and actually remember that TINY little office he used to have prior to his Market Street office. Dr. Hassler is warm, has a sense of humor, stays well informed, and just makes the overall office visit a pleasure. I am very satisfied with our MD-​patient relationship and am extremely happy knowing that I am always in the most capable of hands. Martin, Paul, and Linda have always been wonderful to work with and are consistently reliable and have excellent follow-​through. Once you’ve been to see Dr. Hassler you will not want to see anyone else again.

All I can say is I have been a patient of Greg Sauers for years now and he is simply amazing. His commitment to patient care is second to none and he treats you like an old friend versus a patient. If you need to see a healthcare professional and not sure who to go to, call Dr. Shawn Hassler’s office, you will not be disappointed. They are top notch and Greg Sauers, PAC is absolutely wonderful.

Shawn has been my doctor for over 10 years and he is the best primary care physician I have ever had. He has a wonderful office manner and a warm, caring style of doing medicine. He keeps up with current medical information. And he actually takes time with me when I have an appointment. I never feel rushed as can happen in other medical offices. His entire office staff is equally warm, caring and competent. Shawn is a great man and a great doctor.

Been a patient of Dr. Hassler for almost 10 years now and he and Martin have been so great to work with. They are the type of care providers that really listen to you, take the time needed to understand the issues, give you a hug when you need one, are extremely knowledgeable about dealing with gay men’s health issues, and most important they bring compassion to what they do. Believe me, when you are going through a health issue, having a strong knowledgeable and up-​to-​date with research partner with the rare bonus of having a great bedside manor is what you want from a primary care physician to navigate our complex health system.
As a gay male, dealing with gay men’s health issues, I could not more highly recommend this practice.

Seeing Dr. Hassler is worth the wait! I found him through my company’s benefits directory, and after reading reviews from fellow Unilocalers I said let’s do it. I also was sold on the location (right on Market across from Westfield in the Flood Building.)
I was greeted with a warm and genuine smile and immediately felt at ease. He is very thorough with finding out about what’s up and is well connected with specialists for things beyond his practice. He talks his way through everything he does and is very knowledgable on many subjects.
The office in general felt just a wee bit rushed, but you wouldn’t really realize it because everyone seemed calm and relaxed. They mailed the paperwork in advance so I had enough time to fill it out and gather information; that part easily took me the better part of an hour at home.
I’ve found my new primary care doctor. He’s awesome and he’s got a good, genuine heart with his practice.

I have been a patient of Dr. Hassler for many years now. At first when he had his tiny office on Post. There is a good reason why there is a long wait for a regular appt with him. He is very good at what he does.
What makes him different is that he is very personable. His visit feels like a conversation with a friend. I don’t feel like I’m being examined like a specimen. As someone uncomfortable with doctors this makes him perfect for me. He will take as long as it takes to answer my questions and is very thorough. Often asking questions about what’s going on in my life to see if there’s anything else contributing to any problems I’m having. (my dusty office for instance came up and re was able to remind me that it can trigger my asthma)
He and his staff are very friendly. It seems they are happy to see me when I show up for a visit. Putting me instantly at ease.
Yes. It can take a long time to book a regular appointment. However, I have often been able to see him the same day for an emergency. AND he will make follow up calls in the evening to make sure everything worked out!!!

I have been seeing Dr. Hassler’s PA for a couple of years and he was ok for a PA but for serious issues, he dropped the ball and didn’t seem to understand or have time for medical research.
Luckily for my last appointment he was out ill so I saw Dr. Hassler. He was very thorough, listened to my issues, took a balanced approach to treatment options (not just RX’s) and took his time. He treated me like an adult and gauged what I knew and responded at an appropriate level whereas others do not. Outside of his PA who is retiring soon, the rest of his staff is great and very efficient.
