Mark R. Drzala, M.D.

Dr. Mark R. Drzala

Dr. Mark Drzala is a board certified and fellowship trained orthopedic spine surgeon and has been in practice since 1998. He devotes his practice to the treatment of patients with disorders of the spine and specializes in their care.   Thorough patient evaluation and a focus on education is the hallmark of Dr. Drzala’s practice. While certain conditions have absolute indications for spinal surgery, Dr. Drzala is conservative by nature and typically exhausts non-operative treatment options, whenever possible, before considering surgical intervention. Patients participate fully in the decision making process regarding their care with treatment regimens tailored to meet each patient’s needs.
