Born in Uganda to Rwandese refugee Tutsi parents, I began life in a world of segregation, civil war, and abject poverty. Unable to return to the war-torn place of my origin at the time—and plagued by violent discrimination in my adopted country—I fought to find safe haven. As a child, the only constants were my grandfather, our cows and dogs. Because of Grandpa’s wisdom and our bond, I decided to pursue our love of animals as my profession. This is why I became a veterinarian.

                I studied Veterinary medicine at Makerere University, Uganda; one of the best universities in Africa. I moved to America to advance my training with an internship in Kentucky and to give my family a better life.  I took the American Veterinary Association required tests; ECFVG/AVMA (at Mississippi State University) to get licensed in USA. I worked at a private practice in Boulder for 14 years and now the time came for me to own my practice. 


Dr. Kalenzi, what are some of your favorite places?

My favorite places to hang out are; home with my family, working out at the gym and of course being at work to keep all pets happy and healthy! 

 Dr. Patrick Kalenzi


Kind Words from our Clients


"Dr. Patrick is phenomenal. He was extremely supportive and through throughout the entire process. He scheduled several follow up visits at no cost to make sure my dog was healing properly. Everyone at Rock Creek is so caring and friendly. I would highly reccomend to anyone. Dr Patrick is truly a blesssing to the community."

                              -Andrew H.


 "Dr. Patrick is a top-notch guy, and his knowledge and level of caring treatment exceed (by far) any other vet I've ever known. My boyfriend's dog had a surgical procedure at Rock Creek; the staff went above and beyond to make it as pleasant of an experience as possible. I will be bringing my own dog here from now on."


                        -Sarah S. 


"I had a good experience here. They scheduled me in on short notice and had a quick turnaround time on test results.

Dr. Patrick was very knowledgeable and gentle with my pup. He takes a more holistic and natural approach (suggesting medication only when necessary) which appeals to me."

                          -Tonya N.


 Dr.Lindsay Oklesh

Associate Veterinarian

Dr. Lindsay Oklesh was born and raised on the East Coast but moved to Colorado in 2001. She grew up riding horses competitively in South Florida in the sports of Hunter/Jumper and Three Day Eventing. Although her connection to horses helped to nurture her love of animals, Dr. Oklesh knew “from birth” that she wanted to be a veterinarian. Dr. Oklesh received her Bachelors of Science degree and graduated with honors from Colorado Mesa University (formerly Mesa State College) in Grand Junction, CO in 2007 before attending veterinary school at Colorado State University starting in 2008; she graduated with her D.V.M from CSU in 2012. After graduation, Dr. Oklesh completed a grueling one year internship in Emergency Medicine and Critical Care at Aspen Meadows Veterinary Specialists in Longmont, CO and then moved on to practice Emergency and Critical Care medicine for the past 7+ years at a 24/7 emergency veterinary hospital in the Denver area. During that time, Dr. Oklesh became a certified ultrasonographer and became proficient in many areas of veterinary surgery. In 2019, seeking a change of pace after having her first child, Dr. Oklesh joined the Niwot/Rock Creek team and could not be happier. Dr. Oklesh lives in Lafayette with her husband (Adam), step-daughters (Ashlyn and Kendra), 11-month old son (Elias), two cats (Lulu and Mimi) and her beloved Vizsla (Baron). Her veterinary interests include: emergency medicine, surgery, ultrasonography and end-of-life/palliative care. Dr. Oklesh enjoys spending time with her family and climbing Colorado 14ers, camping, hiking, snowshoeing, snowboarding, kayaking, cooking and yoga.
