Radiocat Co-Founders
Dr. Herring and Dr. Wachsstock are co-founders of Radiocat, a veterinary practice dedicated exclusively to the care and treatment of Feline Hyperthyroidism.
Dr. David S. Herring is a Board Certified Veterinary Radiologist who believes the pet's best interests are paramount and that the treatment should never be worse than the disease. He received advanced training in diagnostic ultrasound, echocardiography, radiography and nuclear medicine, and taught at Texas A&M and the Ohio State University. In 1985, Dr. Herring moved to the Baltimore-Washington area, where he became the first veterinarian to offer abdominal ultrasound and, in 1995, Radioiodine therapy (I-131).
Dr. Rand S. Wachsstock is a graduate of the University of Illinois and has taught at both his alma mater and at Yale University. He has actively practiced emergency medicine since 1984 and believes comprehensive state-of-the-art medical care should be readily available to all pets. Dr. Wachsstock owns and operates the Emergency/Critical Care Service at The Regional Veterinary Referral Center in Springfield, Virginia. In 2005 he was appointed by the Governor of the Commonwealth of Virginia to the Radiation Advisory Board.

The Staff
Clients bringing their pets in for therapy will meet several Radiocat staff members along the way.
Client educators spend time teaching clients about Hyperthyroidism and discussing individual case histories, treatment options, statistics and success rates, procedures, philosophy of care, radiation safety and more. They also coordinate the request for and receipt of pre-therapy blood work from each patient’s referring veterinarian, shepherd the blood work and histories through a review by our doctors, schedule appointments, and generally address client needs. Most of our client educators are trained veterinary technicians and/or have other medical backgrounds (i.e. Emergency Medical Technician training, nursing school, etc.).
Each Radiocat technician has extensive experience in the veterinary field and receives additional training in dealing with geriatric patients, Radioiodine therapy and radiation safety. Radiocat technicians ("surrogate moms") are also assigned to individual Radiocat clinics where they admit, care for and release each patient after treatment. In addition, they provide owners with daily progress reports, make sure each patient’s dietary restrictions and preferences are followed, cuddle patients, make sure patients receive (and swallow) medication for pre-existing conditions, play owner audiotapes and kitty videos, and prepare gourmet buffet plates.
Our technicians and client educators - all of whom are multi-pet owners themselves - work closely with Radiocat doctors, who supervise the care and treatment of each case, as well as provide on-going training and information on Hyperthyroidism. Obviously, our doctors cannot be everywhere at once, so each clinic also maintains 24-hour access to a veterinarian/specialist in the immediate vicinity.
If, in the highly unlikely event that a patient needs medical care during their stay in the radiation ward, the on-site technician notifies Drs. Herring and Wachsstock, as well as the nearby veterinarian/specialist (who provides a second pair of skilled eyes and ears for each case). Radiocat doctors will either supervise or travel to and directly care for every patient’s needs.
