About Horizon Vascular Specialists

At Horizon Vascular Specialists, we provide the Mid-Atlantic region with a modern, non-surgical approach to treating one of the most common yet uncomfortable conditions: chronic internal hemorrhoids. With convenient, state-of-the-art locations in Frederick, Germantown, and Rockville, Maryland, we make it easy for patients to access world-class interventional care close to home.

Our specialists are leaders in Hemorrhoid Artery Embolization (HAE), a breakthrough, minimally invasive procedure that provides long-term relief without the pain and extended recovery of traditional surgery. By utilizing advanced imaging technology in our specialized outpatient centers, we target the root cause of hemorrhoidal discomfort with unmatched precision.

At Horizon Vascular, we combine our deep expertise in vascular health with a discreet, patient-centered environment. Our mission is to help our neighbors in Montgomery and Frederick Counties regain their comfort and quality of life through innovative, office-based treatments that prioritize your safety and a rapid return to your daily routine.

For Horizon Vascular Specialists Patients

Painless, Non-Surgical Relief

Unlike traditional banding or surgery, HAE is a minimally invasive, image-guided procedure that requires no cutting or stitches, significantly reducing post-procedure discomfort.

Convenient Outpatient Care

Procedures are performed in our specialized Maryland offices—Frederick, Germantown, and Rockville—allowing you to avoid the hospital and return home the same day.

Rapid Recovery Time

Most patients experience a quick return to their daily routine within 24 to 48 hours, making it the ideal solution for those seeking long-term relief without the lengthy downtime of a hemorrhoidectomy.

Patient Reviews

I had to write a review as soon as we left Horizon as I was extremely pleased with the level of professionalism and the way my father was treated. The staff in the Germantown location were very friendly from beginning to end... Horizon is the first place that had exceptional service genuinely caring for their patients!
— Yeri C.
Dr. Haider performed an aortobifemoral bypass graft on me. Before this procedure, I could only walk 150 to 200 [feet]... After the procedure, the difference has been night and day. I'm astonished and amazed how I can walk to my heart's content without stopping. My family holds Dr. Haider in our highest regards in his knowledge, professionalism, and expertise.
— Ralph B.
I am so impressed by the level of excellence apparent in every aspect of this practice. From the minute you walk in the office, the soothing atmosphere has a wonderful calming effect. Everyone at the office is always very friendly and patient and caring... Dr. Haider is always very warm and friendly and I never feel rushed or hurried.
