Dr. Charles Blevins

Dr. Charles Blevins:

As founder of Oakton-Vienna Veterinary Hospital, I grew up in Washington, D.C. My love of animals began when at the age of eight, I found a baby raccoon.  I love being at OVVH, because I can care for animals in an enjoyable, warm atmosphere, and my clients are my extended family. In addition to my veterinary education, I have been trained as a cognitive therapist, a skill that assists me in my interest in the human-animal bond and the relationship of companion animals to our emotional and physical health. The Oprah Winfrey Show featured my work with the human-animal bond in 2001. This work plays a big part in my everyday role working with clients' by caring for their pets, but also caring for clients' needs in times of distress. I love the connections I have created and feel very lucky to be at OVVH. In my spare time, I enjoy a variety of outside activities, including kayaking, biking and hiking. I also work out at the gym and take weekly yoga classes.

Dr. Sandy Christmus: 

I spent most of my childhood in South Carolina and graduated from Clemson University with a BS in Microbiology. After graduation, I worked at The Johns Hopkins University School of Medicine as a lab technologist dealing with organ transplants, paternity tests and research studies. I graduated from the Virginia-Maryland Regional College of Veterinary Medicine at Virginia Tech in 1995 and was inducted into the Phi Zeta Veterinary Honor Society while at school. The Vienna/Fairfax area has been my home since graduation from veterinary school. I am past vice-president of The Shiloh Project, a nonprofit group dedicated to helping at-risk youth learn compassion and responsibility by allowing them to socialize and train rescued homeless dogs. I also worked a great deal with Greyhound Rescue, Inc., both pre-and post-adoption. I have a special interest in ultrasonography and have performed more than a thousand sonograms on dogs and cats. My wife and cat take care of me when I'm not at work!

Dr. Jackie Jones

Dr. Jackie Jones: 

I am a native of Maryland, but left to attend the Ohio State University School of Veterinary Medicine, graduating in 1993. My first job took me to California, where I worked in a mixed animal practice, treating ostriches, wolves, cows, pigs, and everything in between! Although the variety was stimulating, it had the downside of being physically risky. Seeking safer work, I moved to the San Francisco area to work for a corporate-owned small-animal practice. Tired of missing my family, I decided to move back to the East Coast and joined the OVVH team! My personal interests include reading, gardening, hiking, traveling, jewelry making and fused glass.

Dr. Lydia Megremis:

I was born and raised in Indiana. I attended Purdue University and received my Bachelor of Science degree in Biology and my Doctor of Veterinary Medicine degree there. Shortly after graduation, I moved to the northern Virginia area and have been living and practicing in the area since then. I have a special interest in Canine Physical Rehabilitation, in which I completed the course work through the University of Tennessee Veterinary School. I enjoy helping patients recover after orthopedic surgery and treating other orthopedic conditions, as well neurological problems. I share my life with my husband, son, and a crazy cat. In my spare time I enjoy reading, cooking, bird-watching, hiking and learning to knit.

Dr. Paula Clark-Fischinger:

Hello! Although I am new to the OVVH team, I have been working with OVVH as a relief veterinarian for many years. I graduated from North Carolina University Veterinary school and I have over 23 years of experience in small-animal medicine. I have been practicing in the Northern Virginia area for the past 12 years. My goal is to improve the quality of life for cats and dogs by providing integrative pain management, nutritional, exercise, and behavioral consultations. I have interests in dermatology, ophthalmology, internal medicine, and soft tissue surgery as well. I am focused on the human-animal bond, getting certified in fear-free handling, and in minimally invasive surgery. I have two teenage daughters, my husband, and a sweet chow chow mix named Hope, to keep me company outside of work. 

 Dr. Diane Heinz:

I received an MBA in Finance from the University of Pittsburgh in 1986. After 10 years in the financial services industry, I returned to my first love, veterinary medicine. I received my Doctor of Veterinary Medicine degree from the Virginia-Maryland Regional College of Veterinary Medicine in 2000 and have since been working in private practice and in the public sector. I am interested in companion-animal internal medicine and enjoy promoting the health and happiness of pets and their owners. In my spare time, I enjoy renovating my house and making stained-glass artwork. I am owned by three silly cats and one very sweet dog.
