I love Dr. Leung and she has been great. Nurses do not wear gloves while giving allergy shot which is scary during covid.

My doctor is Dr Toby Levenson. She is very professional, knowledgeable and friendly. The place is very clean and the staff is friendly and you are seen promptly by the doctor. Accessing the office for medicine refills and other insurance changes are easy. Wonderful service!

Dr. Levenson and the staff were efficient, friendly, and helpful. I had never been allergy tested before (despite suffering through allergies most of my life) and everyone was so informative. Despite helping a few different patients while I was there, Dr. Levenson was very present every time she spoke to me and my care never felt rushed, she even went out of her way to help me get the best price of a medication that my insurance doesn’t cover. I would definitely recommend this office.

I just met Dr. Leung for my first meeting. I was pleasantly surprised to find out that Dr. Leung spends a lot of time with patients going back through medical history and allergy triggers. She is extremely knowledgeable, experienced and most importantly, a very empathetic soul. I loved her commitment to patient care ❤️❤️❤️ I will be a patient for a long, long time. I give her 5 starts. I recommend seeing Dr. Leung and her office staff if you are looking for a doctor that’s committed to find the answers and work with you throughout the process. Every single person I came into contact was friendly, polite, and very knowledgeable. I’m so thankful I found them 🙏🙏🙏

Dr. Levenson is very thorough and orders the necessary tests to diagnose the problem. She follows up with the diagnoses and treats the problems.

Dr, Toby Levenson saved my life. I went to 2 Allergists before meeting her without results and feeling hopeless. A new to me Dermatologist recommended her and I met on a Monday and by Friday we found out the hidden issues through a series of tests. She actually listens to her patients with extraordinary wisdom and knowledge but has a good heart which in turn is why she listens. She gave me the control of my health vs a constant nightmare. This is Mary Turner 😊 I’m using my husband account.

The office staff is very proficient and kind. Dr. Toby Levenson is an Excellent Physician, she knew exactly what my condition was and recommended Body Wash, Clensers for my skin. The Body wash relieved my itchy skin and I am forever grateful, for Dr. Levensons help. With much appreciation.

The Dr and Medical assistant that took care of my daughter far surpassed my expectations.They were both extremely caring and attentive.It was easy to tell that the assistant knew what he was doing and has been doing it for awhile.He did a very extensive skin test panel efficiently and accurately.The Dr took the time to listen to our concerns and gave thorough and comforting feedback.I highly recommend this practice.

Dr. Leung is a knowledgeable physician. She is very helping with my son skin problem, and she is very patient and understanding. The staffs are great, too. I definitely will recommend my friends to come here.

Dr Levenson and her staff are very caring and knowledgeable. Always a pleasant experience.

I think this is a great practice. Dr Leverson is Up to date on the latest treatments. Her team is efficient, and accommodating. I feel not just like a number with a $ sign, but like my physician actually cares about my condition, and it’s treatment. Last year when I was pretty sick, Dr Leverson dedication got me through it.I have been in healthcare on the other side for decades, and know good practice, and this Fremont office certainly a 1st rate resource for the citizens of Fremont.

I have been using Allergy and Asthma for many years. Dr. Levenson and her team have taken great care of me and most of my family. The staff is caring, thorough, and friendly.

I became frustrated with the clinic due to an misunderstanding about their clock/computer system.. i love Dr. Levenson so I decided to try again. However, at each subsequent visit, i received a very cool reception from the front desk personnel. Specifically, eyes avert, im not greeted or acknowledged. In fact, i arrived first one day and i had to ask to nurse if she knew i was present. Im sure Im not the only patient that has gotten irritated and voiced a complaint i dont get it. Move on and be respectful. BTW. the front receptionist spends a ton of time on personal phone calls. Ill be sharing this info with my PCP
