I’ve seen Dr. Kossoff several times my initial visit was to rule out anemia with unknown etiology. Dr. Kossoff could’ve easily assumed everything was fine after he performed my procedure instead, he took the time to rule out another possibility which was instrumental in me getting much-needed treatment. Dr. Kossoff is caring and professional. The staff is also excellent. I am very satisfied with the care I receive.

Dr. Kossoff was great! He did an excellent job diagnosing my GI issues and set out a plan to resolve my problems. I have progressed to the point were I no longer have symptoms. His office environment is excellent. Staff are helpful and he is on time.

I've been a patient of Dr. Kossoff for years now and there is no other Dr. that I respect or believe in more than him. He is a straight shooter and isn't afraid to tell you what's going on. He and his staff are kind arena professional.

DONT go to David Kossoff! He is in it for the insurance aspect and will test you to death but NEVER give results!!! My daughter has suffered a year under his "care". We've FINALLY went elsewhere. Kossoff is NOT to be trusted.

I first met Dr. Kossoff ten years ago and I have only the highest recommendation for him and his staff. I have been treated with a kind and caring attitude by everyone I've met.
in Thurmont, MD |
I would highly recommend Dr. Kossoff. His level of care, compassion and expertise is second to none. Everything was handled in an extremely efficient manner.
in Walkersville, MD |
Dr Kossoff exhibited extreme concern for my symptoms. Recommend him completely.

Dr. Kossoff is the first doctor in the area who heard my symptoms and then actually did tests and figured out what was going on with my stomach. I've had a lot of doctors blow me off and say it was just acid reflux but he actually figured out what was wrong within a few visits and a couple of tests. Would 100% recommend to friends and family. Not only is he great, but his PA is as well and interested in patient care and they communicate well so I didn't feel like I had the same visit twice.

I love Dr. Kossoff and his amazing staff. I would highly recommend. They are caring and very professional. Trust me when I say " They are all about the patient" You matter to them and they take care of you like you are their family. I am grateful to Dr Kossoff for fixing and keeping a careful watch on my conditions. Thank you again. They are amazing. Keep up the excellent care.

Started out great he seemed engaged and working my issue. But then he pawned me off on his PA, and they botched medications multiple times, wrong one, wrong dose, too little so it ran out and on and on. Then condition I saw him far came back and worse, in extreme pain call and can't see him until 5 weeks later? Crazy poor business. Didn't fix the problem, not interested evidently with a pawn off to a PA...not there when you need him. Grabbed my records and moved on. High hopes here...poor

I went into the office very upset and sick, and I was treated very poorly by the staff and doctor. I was scheduled for an endoscopy after 2 minutes of Dr Kossoff coming in, not speaking with me, pressing on my stomach with no explanation. I left more upset and confused. After my endoscopy Dr Kossoff did not speak with me, and only to my mother even though she was not on any release and I was in my late twenties. I will never go back. No bedside manner or respect.

Dr. Kossoff always goes above and beyond to offer you the best care possible. His office staff is excellent and when we call we don't wait and a professional and polite person answers the phone. Dr. Kossoff has both experience and empathy, a rare combination these days. Because of Dr. Kossoff my husband was diagnosed early with pancreatic cancer, and he has a chance to survive it!!
in Frederick, MD |
Dr. Kossoff was very professional and treated me with kindness and concern. He put my safety and well-being first. He didn't just rush in and treat when he saw an area of concern. He referred me to a specialist and then that specialist sent me back to him. He made a plan that was well thought through and it airs on the side of caution. I feel fortunate to have been referred to Dr. Kossoff. I know I am in a doctor's hands that is truly about helping and healing.
in New Market, MD |
Dr. Kossoff is a knowledgeable, caring and insightful specialist. He made me feel secure, and confident on my first visit and has a very calm attitude which attributes to his great bedside manner. I appreciate the fact that he took the time to check on my well being after each procedure and reassured my doubts and concerns. The staff is professional and very accommodating. The whole experience was pleasant and I was grateful for the short wait time.

Dr. Kossoff is an exceptional doctor. He is the most compassionate and caring physician I have encountered. My health was his main concern when I went in for an emergency appointment. His follow up is awesome. I would recommend Dr. Kossoff to anyone I know!
