Bio
What are some of the specific conditions you treat?
As a rheumatologist, I diagnose and treat arthritis and other immune-related diseases and conditions. This includes performing tests to assist in the diagnostic process, diagnosing specific conditions, and developing and administering treatment plans for patients with musculoskeletal or autoimmune conditions. Specific conditions treated include rheumatoid arthritis, lupus, osteoarthritis, gout, psoriatic arthritis, Sjogren's syndrome, fibromyalgia, and vasculitis.
What techniques or procedures do you use in your practice?
Procedures and techniques used in our practice include the ordering and interpretation of blood tests, X-rays, DEXA (bone density) scans, and MRI studies. We also perform joint, muscle, and tendon injection and aspiration procedures using ultrasound guidance. This includes the administration of cortisone and viscosupplement injections.
What would you like patients to know about your approach to care?
The primary goal is to help diagnose and treat the conditions that bring patients to us. This is approached in a manner that allows the patient to feel comfortable. Care focuses on the patient's physical comfort as well as emotional well-being. Care is meant to be accessible and collaborative, with respect given to patient and family preferences, values, and cultural traditions. Patients and their families are part of the care team and share in decision-making. Information is shared fully and in a timely manner.
