Even though he's very busy, it is always easy to get an appointment with him, because he's always willing to work you into his schedule. I've never waited for longer than 10 minutes to see him.

Dr. Kim is amazing. During our initial exam, he was very thorough. We tested over 20 (possibly over…read more40) allergens and discussed alternative methods of treatment rather than going straight into allergy shots, which I appreciated. I ended up taking the shots and his office couldn't be more accommodating. He fully explained the commitment and made sure that I would be up for it. Even so, they make taking the shots as easy as possible for the time constrained. They have open wait times for shots and their waiting room is really comfortable and equipped with wifi. His staff are extremely friendly and very knowledgeable themselves. His office managers are a pleasure to work with (a rarity considering the fact that you've got the health insurance factor). I think it's pretty rare to find a great Dr. as well as an amazing staff. I would highly recommend Dr. Kim. I've been dealing with my allergies all of my life and this is the first time I feel like I'm getting them under control. Although he emphasizes that allergy shots aren't a cure, I feel like the level of care and knowledge that I am receiving is top notch.

I recently called to get epipen refills and have never been treated so rudely on the phone. The receptionist put me on hold for 30 minutes, then when she finally came on she acted very annoyed that I didn't know that their Centerville office had closed. She then cut me off as I was speaking to say that she had someone else on hold. I waited another 25 minutes and she never came back. We will no longer be patients of Family Allergy Center.

Piss poor establishment, this is the second allergist I've been to that sucks. When I first started…read moregoing to them in September I thought they were pretty cool. Update April 15th, 2026. They are not. Getting my shots and testing has been great. I've been trying to get a refill on my inhaler that I've been taking consistently for years. I guess this year my insurance refused to pay for it. But insurance refuses to pay for everything so I wasn't too taken back. Insurance wants me to take a new inhaler. I know to get a couple of the medications I'm on, requires pre authorization. But for some reason this establishment refuses to do that. I've been going back in forth with them for the past month trying to get this medication through the pre authorization process. And this whole month the two nurses handling the pre authorization never initiated the process. They were making it seem like they had a hard time getting ahold of someone with my insurance. But I found out they just weren't fighting for me to get this medication approved. You know the saying "If it ain't broke don't fix it" why put me on a new medication when the one I've been on for years is working perfectly fine. I was fighting back and forth with Britney (one of the nurses)who seemed awesome when I first met her. I told her I wasn't going to take this new inhaler they were trying to prescribe me. Going back and forth with her, I guess she couldn't hear me that well on the phone. So she told me "Call back when you have better service" and hung up on me. I called back 10 minutes later to speak to her again one of the reception ladies says "hold on let me get ahold of her" waited 10 minutes she comes back. "Dr. Shayegan is with patient right now but he will give you a call back shortly" I said "I asked to speak to Britney not the doctor" and she says "The doctor would like to speak with you. he will be giving you a call back shortly". So I guess the nurse got her attitude and decided to let the doctor deal with me. Doctor called me about an hour later (Dr. Shayegan) said he wasn't going to prescribe me my medication. and that even if they pre authorized the medication, Insurance would want documentation on why I can't take their preferred medication list. So that right there told me this whole entire month they submitted the pre authorization. I told him to let them know I've taken their (preferred medication) in the past and it doesn't work for me and He refused. I don't really care what they tell insurance. As long as I get my medication. Again this is not my first time trying to get a medication approved through my insurance. All of my doctors make it simple, I don't know what they do. But they get it done. And I get my prescription in my hand. Anyways he said he will not be prescribing me my inhaler that I've been taking for years. So I will be seeing my physical doctor on the matter. Never had more issues with getting a medication from any practice except this one. Front desk ladies and the couple of nurses that give me my shots frequently. Love and appreciate them. But I wouldn't recommend coming to this place. However if you have no other choice. Beware if you have asthma they might not prescribe you what you know you need, but what they think you need. 1/10 wouldn't recommend

I use to come here for myself and my kids but I stopped going for a few reasons. My daughter has…read moreallergies and we noticed she couldn't breathe through her nose. Dr. Kim had said to give her allergy medication but that didn't work . I have allergies and I know when I take medicine i still have moments where I can breathe through my nose but my daughter nose remained constantly blocked.So we went back to the office and Dr. Kim said she would need allergy shots. That it would help a lot with her being able to breathe through her nose. My daughter was on allergy shots for quite awhile but her nose remained constantly blocked. I ended up taking her to an ENT and it turns out she had enlarged adenoids in her nose that were blocking her being able to breathe through her nose. We had them removed and she could finally breathe through her nose. I had gotten a second opinion with another allergist and they told me my daughter didn't need allergy shots. So it felt like a lot of time was wasted in getting help for my daughter. Other reasons why I would not go back is because there was a nurse ( she gave my daughter allergy shots) and a receptionist. Both of them from my experience had poor customer service skills. Sometimes the receptionist was nice but there were other times she's wasn't. Both of them just came off as snappish and rude.It wasn't something that I wanted to keep dealing with so I took my whole family who went there to another allergist.
