Diana Luplow


Dr. Diana Luplow is a Veterinarian at Founders Green Animal Hospital. She attended Auburn University for her Bachelors of Science in Zoology in 2010, and went on to earn her Doctorate in Veterinary Medicine from Mississippi State University College of Veterinary Medicine in 2014. She began working in the veterinary field in 2002 and her areas of professional interest include dentistry and soft tissue surgery. After growing up in a family of medical professionals, Dr. Luplow knew she always had a passion for animals, and decided to pursue her dream in veterinary medicine - a perfect combination! She says the best part of working in the veterinary field is having the ability to gain trust with animals, while using skills to keep them healthy.

Originally from a small town outside of Nashville, TN, Dr. Luplow currently resides in the Highlands neighborhood of Denver with her new puppy, Mango. When she’s not practicing veterinary medicine, she enjoys watching live music, sports (Auburn Football - War Eagle!), and stand-up comedy. A fun fact about Dr. Luplow is that she spent a month in South Africa working with wildlife and doing conservation work.

Hannah Siebens


Dr. Hannah Siebens is a new Veterinarian with Founders Green Animal Hospital. Dr. Siebens received her Doctor of Veterinary Medicine from Tufts University School of Veterinary Medicine in 2017. She is a Certified Veterinary Acupuncturist and has a professional interest in preventative care, dentistry, and complementary medicine.

Dr. Siebens has been in the veterinary industry ever since she began shadowing at a local clinic at just 13 years old! She always knew veterinary medicine was her calling, as her love for animals goes back as far as she can remember. Dr. Siebens loves to watch her patients grow up and thrive in loving homes and enjoys helping pet parents keep their babies as happy and healthy as possible through all stages of life.

While Dr. Siebens was born stateside, she grew up in London and Singapore. She eventually made her way back to the states when she attended college in New York and then resided in Massachusetts before moving to Colorado in 2020. Now settled in Denver, Dr. Siebens shares her household with her husband and two cats named Piglet and Owl. When she is not in the office, she spends her time running, biking, backpacking, hiking, skiing, reading, and learning new languages!
