What Our Patients Say

Mike Roofian
Dr. Rafi is an amazing doctor and a scientist. As a scientist myself, I really appreciate his approach. He thoroughly obtained my medical records bloodwork requested additional bloodwork and tests, and came up with various ways to treat my condition very quickly. I received amazing benefits, and back to normal life. A very thorough doctor, with such level of knowledge, care and willingness to sit down with me. Also beautiful offices and extremely helpful stuff. Thank you so much Dr. Rafi.
Bill Walker
Dr. Rafi is one of the best doctors I've had the pleasure of knowing. He is knowledgable, caring, and sees things other doctors don't. For example, my former internist let me be hypothyroid for a year and after my most recent bloodwork, it was Dr. Rafi who stated: "You're hypothyroid and immediately put me on levothyroxine. My former internist was blasé, to say the least. While Dr. Rafi is an expert in his twin fields of allergy and immunology, his knowledge encompasses so much more. I trust him implicitly. You should too.

I have been a patient of Dr. Rafi for many years. Prior to switching to Dr. Rafi, I suffered from severe asthma since childhood, almost 60 years. Dr. Rafi spent a considerable amount of time with me to develop a treatment plan based on my lifestyle, including new medications, and regular follow-up visits to monitor my progress. Dr. Rafi has spent more time with me and given more attention than any other previous allergist. For a couple of years now my asthma is the best it has ever been, almost completely abated. His office staff and medical assistants are very helpful and friendly. I highly recommend Dr. Rafi and his office for allergy and asthma care.

Archy
I have been seeing Dr. Rafi for 16 years. He is thorough and knowledgeable while being patient and kind. It has been hard navigating all my allergies and he has helped me manage my symptoms. My only complaint is the office hours. Wish there was Saturday availability or early mornings.
Maurizio Grimaldi
I have been Dr. Rafi's patient for several years. He is very thoughtful, kind and thorough. His office staff are also capable and kind. It is an excellent practice.
Marty Kapp
Dr Rafi has performed magic for both myself (age 60+) and my 90+ year old mother. I developed Asthma at just 2 weeks old and before being treated by Dr Rafi my lung capacity was never better than 65%. Dr Rafi with medication now has me at 125%!! My mother had seen several lung specialists for 30 years for a constant cough which they could not help her. Dr Rafi got her cough to stop in less than 3 WEEKS.

A great doctor who has enabled me to breathe again. Terrific staff.
Sarah Rohrman
Dr. Rafi is absolutely exceptional. From the very first appointment, I felt genuinely heard, taken seriously, and supported in a way that is rare to find in healthcare.

What stood out most is how comprehensive and personalized his approach is. He doesn’t rush, and he doesn’t take a one-size-fits-all approach. Every recommendation felt intentional and grounded in real expertise. He also took the time to explain the “why” behind everything, which gave me a great deal of confidence and trust in the process.

Since following his guidance, I’ve experienced a significant improvement in my symptoms and overall quality of life. I finally feel like I’m getting to the root of what’s been going on, rather than just managing surface-level issues.

I would highly recommend Dr. Rafi to anyone looking for an allergist who is not only knowledgeable, but truly invested in their patients’ well-being!!
Lauren Gerstmann
Our family has been seeing Dr. Rafi for nearly two decades, and it’s hard to overstate the impact he’s had on our lives. He has treated all four of us over the past 19 years with a level of knowledge and diagnostic skill that consistently sets him apart.

What we appreciate most is the time he takes with each of us. He truly listens—both to our symptoms, our descriptions, and to any outside notes we bring—and he uses that information to help guide his treatment plan. His approach is comprehensive and holistic, always looking at the bigger picture rather than just treating isolated issues.

Most importantly, his care has had a real, measurable effect on our quality of life and our ability to function day to day. Our kids are now healthy adults, in no small part because of the thoughtful, attentive care they received from him over the years.

It’s rare to find a physician who combines deep expertise with such genuine care and attentiveness. We are incredibly grateful for the consistency, insight, and compassion he has shown our family.
Nader Chahine
I've had asthma and allergies all my life and have been a patient of Dr Rafi's for many years. He is extremely knowledgeable and has contributed enormously to my health and well-being. Before becoming a patient, I struggled with managing my asthma and allergy symptoms. Dr Rafi diagnosed the causes and provided solutions to dramatically reduce the issues I was having. I feel very fortunate to have found someone that has the expertise to understand my situation and to provide solutions that work.
Hady Chahine
I cannot say enough good things about Dr. Rafi. Dr Rafi has been treating my entire family for well over 21 years. Particularly, my son and I suffer from asthma, food, environmental, and seasonal allergies. I have found that Dr. Rafi aggressively treats our issues, which allows for us to normally move on and function in our lives. My experience with other practitioners is that they give my family and I a very short amount of their time, prescribe something generic, and send us on our way. THIS IS CLEARLY NOT THE CASE with Dr. Rafi. What I will say is that I have found Dr. Rafi to spend the necessary amount of time with me and my family, order the necessary labs, do the research, and accurately diagnose whatever is the cause of our specific issue hampering us.

I have found Dr. Rafi's staff to be efficient, polite, kind and genuine which goes a long way with me. I highly recommend Dr. Rafi to to anyone suffering from anything allergy, asthma or sinus related.
Tanya Kormeili MD
Dr Rafi is incredibly insightful and brilliant. He was able to diagnose a chronic sinusitis in my son that was missed by two other doctors. He is so gentle and caring with his patients. I wouldn't just trust anyone with my kids and he has my full respect and trust. I highly recommend Dr Rafi!
Naira Ter-Margaryan
It's not often that you come across a doctor like Dr. Rafi. He's extremely thorough, knowledgeable, takes his time to ask questions and examine everything to get to the root of the problem. I honestly haven't come across a doctor like this in a long time. Thank you for the care!
Angie Senner Barrick
Can't say enough great things about Dr. Rafi. I went there three years ago with a sneaking suspicion I had some food allergies. He helped me manage it really holistically and made himself easily available when I needed him. You will be happy you saw him!
B C
Dr Rafi is hands down one of if not the bast doctor I've been to. I will be sending all my friends and family to him asap....if you're having any issues that could remotely be related to allergies don't waste your time going anywhere else.
John Chang
Outstanding doctor, if not the best. He really cares about his patients and absolutely loves medicine, all aspects of it. The science, nature, people, health, society, humanity...all of it.
Courtney Messerli
As a long time sufferer of allergies and chronic sinusitis, Dr. Rafi has been extremely helpful in getting to the bottom of my health issues and for aiding me during some of my most severe sinus infections. He is direct, solutions oriented, and explains his process very well, eliminating any anxieties related to my health. Highly recommend him if you have allergy and sinus issues.
Emerald Jones
I’ve been seeing Dr Rafi for two years now. He has fixed problems that I had no idea were related to my allergies. I would never go anywhere else. I highly recommend him for everything allergy related. He is unparalleled in the field, in my opinion. And I have been seeing allergists my entire life.
