Dr. John Yohan Kim

great, very professional, great diagnostic skills and fabulous follow thru, one of the best docs I have encountered in my 70 plus years of asthma treatments

Most caring, and compassionate doctor I have had the pleasure of meeting! The level of care and concern he showed my mom was a breath of fresh air during an extremely difficult time. He is the best doc around! I would recommend him to all family and friends.

They're truly are amazing humans in this World. Through the Pandemic, I had lost faith, honestly, in humanity, decency and general true compassion for one another. I was depressed and had severe anxiety, many serious underlying health issues and not recommended to get the Covid Vaccine due to a severe reaction to a flu vaccine along with my health issues, but Dr. Kim believed in me and believed I could and truly wanted to help me achieve a life without fear beyond Covid so he accompanied me and I got through the vaccine! He gave me hope and a lifeline and very likely saved my life, literally and figuratively ! I am at high risk for severe disease and not being able to get the vaccine would've continued a downhill spiral with my mental health - Every night before bed, I keep him in my prayers as I never have met a Doctor who was willing to involve himself with my care and he couldn't have been more cool about it, genuine and completely down to earth. BEST DOCTOR EVER period.

I saw Dr Kim recently as a new patient and I was pleasantly surprised to find that he had reviewed my extensive medical history prior to seeing me. We were able to discuss several issues at length and he was able to make informed decisions about certain medications I was taking. He performed testing and was able to diagnose my allergies during that visit. He made some calls and he set me up on a therapeutic schedule and the results so far are promising. I had follow up questions after our visit and after submitting an email to him, he took the time to call me and discuss my concerns/questions and he didn't make me feel hurried. Today, most providers are overwhelmed with their case loads and while I'm sure that they don't intend to come across as non-caring, or make you feel like you are bothering them with your questions, they do. Dr Kim told me he genuinely likes the field that he got into and it shows. I would highly recommend seeing him for allergy concerns.

I recently met Dr Kim. I found him to be impressive. He is Respectful, Caring, Knowledgeable, Professional, Courteous. He is one of the best doctors I have ever seen. I highly recommend anyone needing his specialty to make an appointment you will not be disappointed.

WOW -OUTSTANDING!! Office staff was friendly and efficient. Nursing staff was great. Dr. Kim was excellent! Asked questions and not only listened but HEARD my answers. Listened attentively while I explained my problems and concerns. Bedside manner was phenomenal, he talked with me like we were having a friendly conversation about my health. He explained all of the testing and findings completely and developed a plan of action to help me feel better. Before he let me leave, he made sure that I understood everything that we discussed and what and how I was to implement the plan we developed. I left feeling very good about how I was going to help with the problem I went to the office for. HIGHLY RECOMMEND THIS DOCTOR and OFFICE!

A review is not enough to thank Dr. Kim for what he has given me. He has given me the ability to live and function again when every doctor gave up on me. I suffered unexplained symptoms for more than a year with doctors continuing to pass me around and handing me all kinds of medications without any type of answers. Dr. Kim took the time to listen and look beyond what is text book to help solve the mystery. I have worked in the medical field for many years and it is rare to find a physician so dedicated to improving your health. My family and I will be forever grateful to his dedication and compassion. I will continue to recommend this office to everyone I know, as it was recommended to me with the same thoughts as I am sharing today. Thank you for your amazing care!

Dr. Kim is a warm, caring, thoughtful doctor who has taken the time to really listen to my concerns and give me excellent care, including a concrete action plan tailored to my specific situation. I first saw Dr. Kim after enduring a nightmare of a first appointment with another allergist in the area that left me feeling frustrated, confused, dismissed & disheartened. Dr. Kim was quick to put me at ease and assure me that my concerns are valid and I deserve a better experience. He asked questions and he listened. He was happy to answer my questions and explained his findings/the reasoning behind his recommendations without hesitation. I never felt rushed or left out of the treatment plan. In my experience it’s rare to find such a good (aka professional, highly-qualified, intelligent) doctor who is also so generous with their time, energy & compassion. Dr. Kim truly is a gem! I would recommend him wholeheartedly.

Dr. Kim is the most compassionate health professional I have experienced in my decades of health issues. I came to Cornerstone Allergy after my primary physician and dermatologists could not diagnose my problem. Dr. Kim did . He has followed through with clear instructions for me and has given current information to share with my other specialists. He contacts me immediately when called. He takes time to patiently and thoroughly explain things and listens to my questions. His office staff is pleasant and extremely helpful. 5 Stars is not a high enough rating......10/10!

For the past 4 years, I have been seeking help from different allergists and rheumatologists to understand the cause of my hives but was left with uncertainty until meeting Dr. Kim. He reviewed my past history and provided me with a few thoughts on the potential causes. After receiving the results of the tests, his initial thoughts were confirmed and he provided me with a diagnosis. What sets him apart from any other health provider that I have visited in the past, is that he is caring, compassionate, understanding, and an incredibly knowledgable doctor. He explained the blood work so that I can understand the findings and provided clear direction on what I should avoid as well as a plan of action for the next year. For me, one thing that sets Dr. Kim apart from other Doctors that I have visited is, he takes the time to understand what is going on and above that he truly cares about me as a person. He is not only a great doctor, he is an amazing person!! Thank you Dr. Kim!!

I mentioned to my physical therapist new allergic reactions I was having. Dr. Kim at Cornerstone Asthma & Allergy Associates was recommended based on all the wonderful things they had heard from other PT patients. “He’s a great doctor and everyone loves him...a super nice person”. Well, Dr. Kim was every bit of that! It’s clear to see its a bustling practice, but they are a great team, and so well organized. Dr. Kim was able to bring me in right away based on my condition. He is so professional, knowledgeable, and has a very kind, soothing and friendly demeanor. He was very thorough...taking all the time necessary to go over my history. Dr. Kim made me feel so relaxed as if I had always been his patient. For me, this was a breath of fresh air in the medical community lately. This doctor truly cares about his patients. I rarely write reviews, but he deserves my time here, as well, to say I highly recommend him!

I absolutely recommend Dr. Kim! He is an amazing doctor. He is instrumental in the care of my son. Since 2016, he has directed treatment, has assisted in emergencies and he is 100% invested in his patients and their families.

Dr. Kim and the whole team at Cornerstone Asthma & Allergy are fantastic! They take the time to talk to you, but behind that, they are kind, supportive, and compassionate. Growing up with multiple food allergies and continuing to live with them can sometimes be difficult, and not everyone understands. But Dr. Kim understands, and his compassionate care stands out among the rest. Several weeks ago I had a food challenge for shellfish, and I was extremely nervous! Dr. Kim stayed late, and stayed in the room with my fiancé and me the whole time. Dr. Kim is the epitome of what a doctor should be and I am so glad he is my allergist! As a celebration my fiancé made me a shrimp dinner as pictured below!

Unfortunately my opinion of Dr. Kim is that he cares more about making money than the health of his patients. I would NOT recommend this office for anyone as their are much better allergists in the area.

Dr. Kim is a wonderful, compassionate physician. He truly cares about his patients and takes the time to listen and help resolve your issues. I have been under his care for about a year now for a skin condition called CIU, which is chronic hives. When I first came to see him the itching and redness was so bad I could hardly sleep... He ran tests, diagnosed me and started treatment. Although this condition has flareups and can be very uncomfortable at times, I know that I am in good hands with Dr. Kim.

I have know Dr. Kim for the past six years and maintain complete trust in him as a practitioner. There are several reasons: he is highly trained in his specialty, works well with referring physicians, caring and eager to help stop or reduce patient's suffering, willing to suggest new treatments, and maintains an equally caring office staff. I could go on and on about Dr. Kim, however, there is one more thing I'd like to mention-he is a beautiful person. He has no attitude, speaks with you on your level, and is a wonderful communicator. I recommend him 100%.

I went to Dr. Kim because my eyes were swollen shut. Not only did he diagnose that issue right away but also diagnosed my ongoing GI issues that my GI specialist couldn't. He listened to everything I had to say and explained why he prescribed the medicine he did. Dr. Kim was so helpful, and I felt better within a few days! Dr. Kim also called me the next day to make sure I was improving and to answer any other questions I had. He is the best!

Absolute Best allergist in South Jersey!!! He listens he cares and he gives me hope for good medical care today. If every doctor practiced like him health care would be different. He’s up to date on all the new treatments and his compassion for people shines. His staff is always friendly and helpful. Since getting shots I feel sooooo much better during the allergy season. He helped me so much.

I could not run nor barely climb stairs until I met Dr. Kim. Thanks to him, his team and a shot of Fasenra, all that has changed. With my asthma and chronic cough under control, I can now climb stairs, run and do the things I used to without fear of attacks. My chronic cough is on its way to being chronic no more...Thanks Dr. Kim for everything, from the “entire” Robinson Family....

Dr. Kim and Cornerstone Allergy are the best thing that have happen to my asthma. I have severe allergic asthma and have not been in the emergency room or hospitalized since he has been treating me. I would and do recommend him to my friends and family.

This has to be the best doctor's visit I've ever had. From the minute I stepped into the office, I knew I was in the right place. Staff were wonderful and Dr. Kim was amazing! He took the time to listen to my health issues and did the most thorough exam! I had all my questions answered and more. I've already referred my friends and family to him!!!

I've seen Dr Kim for the past 3 or so years. He's honestly the best doctor I've ever seen. He is patient, thorough, empathetic, and all around wonderful. I would and have recommended him to everyone I know in need of an allergist.

Fantastic doctor!!!!! Great bedside manner, very patient and thorough. The staff is excellent, warm, and kind. Would highly recommend Dr. Kim to everyone!

Dr. Kim is wonderful - he spends as much time as is needed every single time you see him. He is extremely thorough and relates very well to teens. He listens attentively to you and carefully considers options and explains everything so well. Asthma/allergy medications can be very confusing, but Dr Kim communicates everything clearly. Would highly recommend him.
