Didn't address my anxiety issues.
Listened very well to my health care concerns. Very informative. Compassionate. I am a registered nurse. Highly recommend this doctor.
Dr. Clarke is great. He doesn't make you wait at all, is thorough, asks all the questions himself (vs. nurse) and then gives you advice.
Fast, friendly, professional and knowledgeable...what more could you ask from your physician?
My appointment with Dr. Clarke was exceptional. He took my vitals and preliminary information himself, so it was very personable from the start. He explained aspects of my health in an easy to understand way and eased my concerns.
Dr, Clarke was thorough, professional and very respectful. I like that he created a dialogue rather than turn the conversation to a monologue. He has an easy style that makes a person want to share information with him.
Prompt and explains everything that you ask in whatever manner you might like (detailed, or simple explanation). Would highly recommend!
It was my first time with Dr. Clarke and he was timely, clear and thorough.
Dr. Clarke was very knowledgeable and thorough. I was impressed by his medical knowledge, and would certainly recommend his services to others.
Dr. Clarke was very professional and courteous. He took the time to listen to my issues and was very helpful and patient.
Doctor is very thorough and nice!
Very thorough in taking my history and physical exam
Dr. Clarke always shows undivided attention to his patients and does a great job not only explaining what he is doing, but being realistic in his explanations and expectations (not just going to say everyone needs/can always get 8+ hours of sleep a night). I included a list of my chief complaints in my zoc doc appointment and not only had Dr. Clarke read the list ahead of time he had clearly taken these complaints into account when preparing for my visit.
I like Dr. Clarke a lot. He's a cool guy, and very straight-forward and professional. He did an excellent job following up with me.
Dr Clarke was very friendly and helpful. He took the time to answer my questions and explained my illness in detail. Highly recommend!

Solid gentleman. Approachable , courteous and professional. Answers all questions and made my routine physical a breez e
Very pleasant experience. Took his time and covered all of my needs.
Excellent doctor. Dr. Clarke is thorough and spends time with the patient. I recommend him
Office is odd. He was the only person there. No receptionist. A one-man band. Besides that he was very nice and very thorough with his questions.
Saw Dr. Clarke for my annual physical. Was very prompt and quick. There's a diagnostic center only a few blocks away so you can easily get your blood work done same day. I called him the next day and he answered personally to give me an update on the blood work, which was really helpful
Dr. Clarke was great!
Very knowledgeable, and is someone who is easy to confide in. Will be going back again.
Great, thorough primary care physician.
Visting Dr.Clarke is always an informative and overall good experience. There is usually no wait when I arrive and he answers all of questions and concerns by the time I leave. If I have follow questions he is very easy to get in contact with. Very knowgable and good attention to detail. Highly recommend
You will have his full attention. He is thorough. He personally answers the phone when you call to confirm your appointment. I will definitely return when the time comes for my next doctor's visit.
What I loved about Dr. Clarke was how patient he was in explaining to you every step of what he was doing and answering all of your questions. It was so refreshing for a doctor to be so transparent and willing to answer all of your questions. I highly recommend Dr. Clarke.
Dr. Clarke was great! He took my appointment on a holiday, and was available as soon as I walked in the door. He was very thorough and asked a lot of questions before giving a diagnosis (I really liked that)! I also like that he took care of everything himself from intake, to taking my pressure, making a diagnosis, and discharging me. Overall, Dr. Clarke was excellent with assessing my condition.
He was very thorough and asked a great deal of questions. Great doctor!
Courteous doctor. I will considering going back to see him if I ever can't get in to see my GP.
I was so pleased with Dr. Clarke! He was extremely kind, thorough in gathering medical history, and gentle in his exam. I left his office with an order for blood work, and a script to help me feel better. He's ideal.
Overall very good doctor. Addressed all my concerns quickly and thoroughly
Very thorough and highly recommended.
I came in, describing my symptoms and Dr. Clarke said that all but one of my symptoms pointed to one thing, but that one symptom if I was sure about it, points to another, and prescribed me medicine for it but recommended to hold off, which I did. Dr. Clarke's diagnosis was correct and I didn't need the prescription.
Very much enjoyed my experience with Dr. Clarke. He was very friendly and helpful. He also explained his tests in a way that was easy to follow. Highly recommend.
Very attentive and collaborative!
I appreciate Dr Clarke's gentle demeanor and thorough assessment as well as proactive recommended health measures.
Dr. Clarke asked open ended questions that allowed me to explain what was going on with me. Very warm presence and bedside manner.
Dr Clarke was ready to see me right at my appointment time, and he was very thorough with the examination/questions.
Pros: - Very professional and polite - Answered all of my questions, I appreciated his candor when describing the benefits / drawbacks of certain courses of action. - I never felt rushed. Cons - None
Dr. Clarke was great! He checked me in himself and was very thorough with the questions he asked. He was able to get blood work done for me and referrals for other doctors I needed to see. It was a very pleasant experience.
This was the best doctor's visit I've ever had. He was thorough, and asked many questions to get the full context (something I've never seen a doctor do well). I will be coming here from now on. Amazing.
Dr. Clarke is a professional, shows genuine concern, and was quick to answer my questions. He is very likable and makes you feel comfortable.
I felt that he was concerned about me as a person, treated me in a caring manner and is a highly-skilled healer.
Very attentive and open - felt like he was genuinely concerned with my well-being. Made me feel comfortable quickly.
Small office (just the doctor) but good bedside manner and thorough physical exam. He could not do any urine/blood testing there but sent me to another facility to get the tests I had requested done.
Very friendly and timely. Seemed very knowledgable. Will definitely be returning!
Doctor Clarke was very polite and professional. I had been looking for a general practice doctor and tried him out based on reviews. He did not disappoint! Clean office and quick, I will be seeing him from now on.
My visit with Dr. Clark was excellent. No wait time, efficient, helpful. His bedside manner exceeded expectationts.
Excellent I am a registered nurse and would recommend Dr Clarke
Professional but approachable. Direct but always courteous. As a GP or an internist, he's as good as any that you'll find.
Very professional, thoughtful and considerate !
I went to see the doctor the first time and he prescribed me stress echo test that costed me thousands of dollars. Nothing came out from that test - everything was normal. I wish I had gotten a second opinion before getting the test done.
It was okay... the doctor never even got back to me about my blood test results. I'm not even bothering calling back again, just got another appointment set up with another doctor.
Extremely kind and professional Doctor. Highly recommend.
Very thorough exam and diagnosis.
It was very unusual there is no receptionist. Just me and him in the office so my first thought was he could kill me and no one would know. But I remembered he had a doorman so at least someone say me go up to his office. He didn't really address my concerns he has a bad bedside manner. Very bland.
A professional doctor and easy to talk to
Very attententive, and explains his reasoning well.
Dr. Clarke seems to be a great physician. He is very knowledgeable and thorough. I was very pleased and look forward to my next visits.
I really liked Dr. Clarke. I arrived early, and was surprised that he was the one who checked me in. Not only did he know who I was, he knew why I was there. At exactly 3pm, he called me back. Right on time. I think I've only ever had that happen ONCE! I thought he had a very kind manner, very professional. I haven't seen a male doctor in years, but I felt safe with Dr. Clarke, and I didn't feel rushed, which is always important.
Very nice and professional.
Dr. Clark was an excellent choice. He provided a physical for my son, and was able to make a referral to a hand specialist for an injury he had. My son said, he was very detailed and had excellent bedside manners. Dr. Clark will be his doctor while in Chicago.
He is good. Right on time (unlike so many doctors). Understood my issues very quickly. Gave me additional advice on some issues I hadn't researched myself. Can't say a single bad thing.
Second appointment with Dr. Clarke. My original appt was to get a form filled out for school and he pointed out that I would likely need to get an update for an injection. He was right - thus the follow up. When I arrived he let me in quickly, but didn't realize that I was there to get the injection so he hadn't ordered it. He referred me to a clinic a few blocks away that he said was walk-in friendly. When I called, the clinic he referred me to they mentioned that they are not walk-in friendly. So now I will have to take more time off of work to go and get this taken care of. Not sure where the confusion was on his part, but pretty frustrating to deal with.
I enjoyed my interactions with Gregory Clarke. He seemed to know what he was doing, and did a good job of assessing my overall health. He was a cool dude.
Dr. Clarke was quick and professional. His office is a little outdated, but he's friendly and efficient.
He was very quick I was seated right away. He was very thorough with his questions and I felt he really listened to my answers. He was logical with his next steps, but I was hoping for a little more information. overall I would see him again
Excelent, take the time to make the proper evaluation and is very professional.
Dr. Clarke was very patient with me and had a wonderful bedside manner. He gave me the advice and reassurance I needed and I am definitely going to be a returning patient!
Professional. Caring. Listens. Very mindful professional.
He seems like a good doctor, but there was no one in his office except the two of us. He was very professional and kind, but it made me uncomfortable that there was no other staff present.
Dr. Clarke was extremely thorough, asked tons of questions, and listened to determine the best diagnosis. I look forward to coming back to his office for follow up on each suggestion provided.
Almost completely devoid of bedside manner. Essentially robot-like. Made me feel very uncomfortable. However, he asked plenty of questions and certainly seemed competent.
Dr.Clarke is amazing. Thank you
After arriving at Dr. Clarke's office he saw me immediately, which was very nice since I had to get back to work. Dr. Clarke was very thorough in learning about about my health history before his diagnosis. I was impressed and highly recommend him.
Pleasant visit. Dr. Carr was professional amicable and I think he's acquired a permanent patient
Dr. Clarke was very professional and took time to take down my medical history and run through all scenarios to find out what ailed me.
Office was a bit strange and seems like nothing was digitized yet. When I got there, there was no one to greet me like a receptionist or anything. I went to get a wart frozen off and it came back. Went elsewhere and they took care of it
My grandson Taveres said that he liked Dr. Clarke because he asked questions and explained things during the examination.
Dr. Clarke was very tentative. He asked detailed questions about my health as well as my family health history. I look forward to building a lasting patient and doctor relationship.
Dr. Clarke was very professional, courteous and thorough. He took the time to explain things and ask the right questions. No one enjoys visiting the doctor but he made it as pleasant as it could be and helped to lessen my anxiety.
He was very attentive and listened to what I had to say, asked questions and took the time to discuss his findings. I did not feel rushed and liked that he personally called me to discuss my lab results.
Very friendly and thorough. Highly recommend!
VERY thorough and thoughtful about his patient's diagnosis and course of treatment.
Dr. Clarke is very professional. He asks lots of questions to ensure he understands what is happening. Was flexible in where follow up lab work could be done.
Very efficient, addressed my concern and more
No fuss, and no waiting which is such a great experience.
I needed to find a new PCP due to BCBS eliminating my previous Obamacare insurance plan. My new plan had a much smaller network and pretty much all the doctors at Northwestern and Rush were out. I saw high reviews for Dr Clarke and he accepts my BCBS Blue Choice insurance so I decided to give him a try. I am glad I did! It was a breeze getting an appointment with him right away using Zocdoc. He runs the office by himself, so I didn't have to deal with any clerical staff. He saw me right away. He listened carefully to my issues (2 of them, both kind of embarrassing) and made careful notes. He diagnosed one of my issues and told me to go to a specialist for a particular procedure. The other issue he said he could not diagnose, but said the same specialist may be able to. I went to the specialist who confirmed Dr Clarke's diagnosis of issue 1 and performed the exact procedure Dr Clarke said was needed. The specialist was also able to diagnose issue 2 like Dr Clarke said he might. At all times, I thought Dr Clarke was completely professional and well informed. He is board certified and is an instructor at Northwestern according to his bio. I appreciated that he was willing to admit he couldn't diagnose one of my issues but knew who might be able to. He also billed me in a favorable way. I think he's way better than my old PCP at Rush. I have no idea why he is not more popular and completely swamped with patients. I kind of hope he stays this way as it was great being able to get in right away to see him!
He listened to my concerns and diagnosed me properly as well as gave me a prescription for treatment.
I think he was not personable at all. I think a doctor should know how to engage with new clients and to calm them down from being nervous. Dr. Gregory had no personality or seem uptight about something.
Comfortable, thorough, empathic. Glad I found him.
He listened carefully and asked a lot of questions. He was patient to answer all of my questions and came up with a plan for testing/diagnosis. Will be going back to him in the future.
Dr. Clarke was prompt, thorough, and informative. I definitely will be going back when needed.
Very good Thorough and personable Seems very knowledgable Would see again
Saw me for a last minute appointment on Christmas eve morning for something I needed to check up on before the holiday. Thanks!
Dr. Clarke was wonderful. Previous physicians always seem rushed for the next appointment. Dr. Clarke was patient, asked a lot of questions and really wanted to know what was going on. Recommend!
Dr. Clarke was kind, very thorough, and took the time to answer all of my questions. That was the easiest (and quickest) appointment I've had in years. Would absolutely recommend him!
Dr. Clake was very helpful and thorough during my appointment. I'm very grateful for being scheduled to see him so quickly.
Very thorough, very pleasant doctor. Been to a few in the last few years and Dr. Clarke is my favorite thus far. Thanks for a good visit!
Dr. Clarke is very attentive. He used all the information from Zoc Doc so I was seen within two minutes of arriving at the office. He answered all my questions and was in no rush- my exam was thorough. The office is small, minimal and old-fashioned- when I went he appeared to be the only one there so he collected my information and insurance before bringing me back to the exam room. I would definitely recommend him if you work in the area and are looking for a new PCP.
Very patient, thorough, and listened well.
Great fast and easy!
He answered all of my questions and was very kind.
Dr. Clarke was extremely thorough in his examination and responded to all the questions we had. He is incredibly professional and I would recommend him to everyone.
Dr Gregory Clarke could not have been nicer. He made me feel instantly comfortable. I was early to my appointment, and so was he! I would definitely recommend and definitely return.
Reasons in which I would not like to make public, but his assessment is bias degree or no degree. That was the first and last time I saw or will see him.
Very professional and makes you feel comfortable.
Very thorough, small office, and detailed doctor!
Dr Clarke was very nice and had a great bedside manner. He was professional and the appointment was quick without a wait.
Dr. Clarke was wonderful. He saw me as soon as I walked in the door. He was very thorough with his questions and really seemed to cover all the bases with my general health, even though I was there for a very specific reason. He was understanding and really nice. He wrote me an Rx, and I called him back afterwards to ask if he could prescribe a generic brand instead, and he called the pharmacy right away to take care of it.
Respectful and was thorough in The exam I would visit him again
Great experience. Best doc I've seen in Chicago by far!
Dr. Clarke was very professional and had almost no wait time.
Very professional doctor. I just thought the office environment was a little old and dated. I'd prefer to go somewhere without carpet on the examination room floors.
Just as awesome
He was very thorough and allowed time for me to ask all of my questions which he answered with full consideration
Very professional and easy to talk to.
