For Horizon Vascular Specialists Patients

Painless, Non-Surgical Relief

Unlike traditional surgical revisions, our techniques are minimally invasive and image-guided, requiring no incisions or stitching, which greatly reduces post-procedure discomfort.

Convenient Outpatient Care

Our procedures are conducted in our dedicated Maryland offices—Frederick, Germantown, and Rockville—allowing patients to forgo hospital stays and return home on the same day.

Rapid Recovery Time

The majority of patients resume their regular activities within 24 to 48 hours, presenting an ideal solution for those desiring permanent relief without the prolonged recovery typical of conventional surgery.

Patient Reviews

I felt compelled to write a review right after my visit to Horizon because I was extremely impressed by the professionalism and the quality of care my father received. The Germantown staff were welcoming from start to finish... Horizon stood out as the first place with outstanding service that truly cares about their patients!
— Yeri C.
Dr. Haider performed a complex procedure on me. Prior to this intervention, I could walk only 150 to 200 feet... Following the procedure, the improvement is remarkable. I am amazed by how I can now walk freely without needing to take breaks. My family holds Dr. Haider's knowledge, professionalism, and skill in the highest regard.
— Ralph B.
I am thoroughly impressed by the excellence displayed in every aspect of this practice. From the moment you enter the office, the calming environment has a soothing effect. Everyone in the office is consistently friendly, patient, and attentive... Dr. Haider is always approachable and kind, ensuring I never feel rushed.
— Lori S.
