The Benefits of Urgent Care

Urgent care provides easy access to patients seeking care for various illness and injuries that should be taken care of sooner rather than later. Although these problems can often be dealt with in a primary doctor’s office, urgent care is able to assist when a patient either doesn’t have a primary doctor or the primary doctor is unable to see the patient at a time that meets the needs of the patient or their problem. In addition to regular business hours, urgent care offices are open weekends, evenings, and most holidays. Access to Priority 1 Urgent Care is easy, you never need an appointment to be seen.

Primary doctors do an excellent job providing preventative health care and looking after a wide variety of chronic medical needs. Urgent care is designed to treat the problems facing you today, and the primary doctor may suggest a visit to Priority 1 Urgent Care if they feel you would benefit from the kind of services found at an urgent care practice but not always available in a primary doctor’s office (EKG, stitches, X-Ray, IVs, etc).

In cases where your primary physician might send you to a hospital emergency room for a non-emergency condition, urgent care can eliminate a lot of the waiting and expense usually experienced in the ER since urgent care is always practiced at a much lower cost compared to an ER visit. At Priority 1 Urgent Care our goal is to provide high quality acute medical care, provided by a team of dedicated and experienced urgent care professionals, 100% focused on caring for you.

 Dr. Jackcy Jacob is a double board-certified physician, specializing in both Pediatrics and Internal Medicine. She earned her Bachelors of Science and graduated Summa Cum Laude from the accelerated Physician Scientist Program at Rensselaer Polytechnic Institute. She then earned her M.D. with distinction in research from Albany Medical College, and went on to complete residency in Medicine-Pediatrics at Baystate Medical Center in Springfield, Massachusetts. A highlight of her career was working as a hospitalist at the Stratton VA Medical Center in Albany, New York where she loved serving veterans from World War II, Korea, Vietnam, and the Gulf Wars, as well as post-9/11 and peace time eras.

Prior to joining the medical staff at Priority 1 Urgent Care, Dr. Jacob gained experience as an urgent care physician working for several years at another local urgent care provider. Jackcy explains “I love giving patients the extra attention that really sets us apart as care-givers, I see myself as a partner of my patients in their healthcare. I value building the physician-patient relationship, which is especially challenging and, in many ways, more rewarding in the setting of the ultra-short urgent care visit, where patients need to feel safe and listened to while given expert health care during a very short time frame.”  

In her spare time, Dr. Jacob is usually picking up after her own young kids, which she actually looks forwards to since one of her favorite pastimes is organizing and attempting to "create order out of chaos." She loves living in the Capital District, where she eagerly anticipates the autumn colors and winter snowboarding.
