Katie Marks-Cogan, MD - Clear Allergy

I wish Dr. Marks and her team could run my entire life. She takes the time to customize treatments and find fixes for my severe allergy issues, and it truly means a lot to be listened to and cared for.

Her team - Ally, Michelle, Jeanie, and Sofia - are all patient and professional. I was coming in once a week for two years and was treated well every single time.

I'll also gently mention on the bait and switch charges a few others report below - call your insurance. I've had severe allergies for many years, and when I get an unexpected bill, it's (without fail) an issue with my insurance policy changing or an incorrect billing code applied by the insurance company - it's never been Dr. Marks or her team.

Dr. Marks is great and I can't recommend her enough.

Very disappointing consultation experience. We had a 10 minute video consultation with Dr. Marks Cogan to determine if my child should be tested for allergies. Ultimately, it was decided it wasn't a fit. We then received a bill for $377 after being told we don't qualify for her services.

I don't recommend using Clear Allergy if you aren't 100% sure you have allergies as you will be charged. I wish I would have read the reviews before hand because it seems to be a common issue with this office.

For over a month, they have been injecting me with the incorrect allergy shot. I have experienced major setbacks in my allergy shot progress and now have to start all over, along with an unexpected rise in allergies this week as a result.

She is one of the best physicians around - thorough, kind and caring. I think myself lucky to have been referred here. You will be too!!! Top notch

De. Marks-Cogan is kind, thorough, incredibly smart, and just a phenomenal doctor. I have a high deductible plan and felt their billing practices were fair and straightforward. It was to know what I would owe before anything happened. Drove all the way from Orange County and could not be happier.

While my actual visit at Clear Allergy was fine, enjoyable even... their billing practices are ridiculous. It's such a bait & switch, and I'm extremely frustrated at the piss poor service I've received following my visit. After paying the initial co-pay and authorizing a $250 hold on my card, for what was supposed to be the maximum amount I'd have to pay if my insurance didn't kick in, I received another bill in the mail. Do not tell your clients that the price for your service is going to be X, and then hit them with additional fees a month later! I called and spoke to their billing office, where some condescending woman kept talking over me and trying to explain to me how deductibles work... Lady, I know how deductibles work. Tricking people into getting a service that costs more than the advertised price is super frustrating and is only going to lead to more dissatisfied clients.

I do not recommend this clinic. I went here for a simple skin allergy test, which took about 20 minutes. Prior to the appointment I was given a very specific price. A month later, I received a bill for double that amount with no explanation on the increase. I have tried to contact their office multiple time with no resolve.

We discovered our 20-month old daughter had a food allergy through a scary episode over the Thanksgiving holiday weekend. Dr. Marks-Cogan was highly responsive and very helpful in navigating us through what to do as well as what to expect over the next few days. She quickly brought us into her office the following week to do a follow-up and confirm/test for any other related allergies as well as train us parents on how to handle any future events. Because she is a mother herself, she knew exactly how to handle our daughter and make her feel safe during what could have been an overwhelming visit. We feel very indebted to Dr. Marks-Cogan and are so thankful to have her in our lives!

My family has had an amazing experience with Dr. Katie Marks-Cogan and her office at Clear Allergy. When our daughter had a pretty severe skin irritation and vomiting to something that seemed like an allergic reaction we reached out to Dr. Marks-Cogan. She responded immediately and set up a time for us to come in right away. It is obvious that she is so knowledgeable and very quickly honed in on the potential issues which she discovered after a quick test were two nuts. You can really tell that she cares for her patients and made us feel very comfortable that we would be able to handle this and that our daughter was going to be ok after such a scary experience. We can't highly recommend Dr. Marks-Cogan enough as she has taken the best care of our family in every possible way.

Such an amazing doctor, great bedside manner who I felt actually listened to my concerns. Definitely will be coming back!
