Do not use this group if you need a sleep study. After having the sleep study done they tried to get me to take another sleep study since theirs was not detailed enough. Then when they ordered my cpap machine, they stated that I would receive it in a week. 1 week later I call in they say they dont have any idea and make me call the distributor. After being on hold for several hours the distributor tells me its because this doctors office did not fill out the full order and they are missing information. After calling back the doctors office they rudely state they filled out all the information needed and tell me they will fix it. Needless to say this group has no idea what it is doing and is just trying to push for as much money as they can. I would suggest using anyone other then them. It makes sense that they are crooked and incompetent since they are associated with Brookhaven.

I am so glad this group was recommended to me. I feel comfortable with their recommendations and I feel better! I did have to wait a while for my initial visit in the office, but once I was a current patient, they have always there for me. If I dont feel well or have any concerns, they will make sure I am taken care of quickly. I will recommend to family and friends in the area in a heartbeat.

Informed by PCP I needed a Pulmonologist for severe Breathing & Coughing issue. I called Dr. Gillerans Office and was informed that there was no available appointments until April -- 3 months away. During the call I was repeatedly coughing -- Nurse asked for my phone # and name and said shed call me back. Within a few hours the Nurse called me back and gave me an appointment for 3 days from then -- it was an after 5:00 P.M. appointment so I am assuming the Doctor must have had me added onto the end of her work day. I am grateful for Dr. Gillerans skill and ability and I am now feeling much better and have a follow-up appointment this week.Follow Up: Almost a month later --Meds finished 3 weeks ago and still breathing well and no Wheezing or Coughing -- Looks like Dr. Gilleran got it under control. Feeling much better. Thanks !

I was recommended here by my doctor and I was very satisfied with my visit. You can tell the staff works hard to ensure the best care for each patient. Even though I had to wait some time for my appointment it was well worth it and I would highly recommend this practice for anyone seeking expert care from a pulmonologist.

DONT recommend this office at all. 2 months later i still dont have my CPAP mask supplies and the office staff down from the manager to secretary have done nothing to help. Will be following up with the proper BBB to report Dr. Mattoo and the entire staff. Should anything happen my daughter has been advised and has specific instructions on not only this office but my attorney as well.

I used to be a patient of Dr. Gilleran’s at her old location and thought she was very friendly, helpful, and interested in my care and took her time to become familiar with my issues and how to treat them. Years later when I needed additional care and went to her new location, her demeanor was very different and the visit very rushed. I didn’t really feel that I received the appropriate care I needed but let it go and figured they just had a busy day.It’s now a few years later and I’ve been very sick for the past few weeks and was told I need to follow up with a pulmonologist right away. I contacted dr. Gilleran’s office and was told they’re booking appointments out in May right now. I explained I needed to see someone sooner since I am sick and having trouble breathing and would have to find a different doctor if they can’t see me. They were happy to let me go as a patient and look elsewhere instead of finding some day and time sooner than May to fit me in. I am very disappointed in how this practice is now, I’m not sure what happened but it’s not what it once was. I cannot recommend Dr. Gilleran at this point, not if you want to actually be seen in a reasonable amount of time. What’s the point of seeing a specialist 3 months from the day I’m really sick and can’t breathe well?

Dr. Gilleran is very kind, professional, and caring! I would recommend her to anyone!!!
