A team of passionate animal lovers focused on being the best in everything we do. Because when it comes to your pet, we will accept no less.

Dr. Sam Lane

I vividly remember Dr. Marcus’ brown, wood-paneled station wagon pulling up into our driveway to pay our Labrador retriever, Stormy, a visit. He looked like the classic old school veterinarian making house calls to examine and treat his patients. He had thick gray hair and wore a traditional white lab coat that cut off just beyond his beltline. After exchanging pleasantries with my mom, he examined Stormy, administered her vaccines and retrieved a sample of blood. Years later, I graduated from veterinary school at the University of Missouri in 2002 and traveled to Wheat Ridge to complete their coveted internship. For several years, I worked with some of the best doctors at the best hospitals in the Denver area. I honed my skills in surgery and medicine and learned how to use the many tools in our profession including ultrasound, laparoscopy, and digital radiography. Then, I was recruited by Pfizer Animal Health (now Zoetis), the largest Animal Health company in the world. I served as a technical advisor and educator on their many innovative treatments for dogs and cats. We introduced new cutting edge treatments for pet allergies. We created the best medicines to stop vomiting, itching and even anxieties due to fireworks. Now at Golden Paws, I want to bring all of these experiences together. I want to be your neighborhood veterinarian, like Dr. Marcus was for my family. In addition, I want to deliver the highest quality medicine for which my experience and training has prepared me. My wife, Amber, and I along with my daughters Hannah and Maggie thank you for allowing us to treat your furry family members. Tater Tot, our Golden Retriever, is also grateful as far as we can tell :)!

Dr. French Aguirre-Wong

I truly believe I have the best job in the world. To be able to work with humans and animals everyday is a delight, not to mention the fact that the veterinary profession touches everything—farming, textiles, sports, companion animals, and even human medicine. They all depend on a veterinarian to make sure animals are in good health. I love how diverse one job can be and how closely it ties us to animals.

Though I didn’t always know I wanted to be a vet, I first attended the University of Denver for a BA in Ecology. Then, after four years of curating plants at the Denver Botanic Garden and the University of Denver Arboretum, I realized I had to fulfill my true passion. I earned my Doctor of Veterinary Medicine from Colorado State University where my special interests became ophthalmology, dentistry, orthopedics, and surgery.

My mission with Golden Paws is to share my knowledge with clients so that we can improve the quality of life for our companion animals and make this care part of daily routine. I’d like to show you how fascinating our profession truly is.

When I am not practicing medicine as Dr. French, you can usually find me rock climbing at one of the many crags here in Colorado or in Indian Creek Utah.

Tomoko Jensen-Otsu


Animals have been a part of my life since I was a child. My first dog was a retired sled dog from Alaska. We explored the woods of Alaska and I have many fond memories of her pulling me on a sled. This was my first experience of the value of the human-animal bond. Since then, the importance of animals in my life has continued to grow.

I spent my college years at Dickinson college in Carlisle, Pennsylvania where I earned a bachelor of science in physics. I then spent 4 years working in the nuclear energy industry at Pacific Northwest National Laboratory in Richland, Washington and then at the Nuclear Regulatory Commission in Washington D.C.

After four years in the nuclear industry, I decided to make a career change and followed my passion for animals to veterinary school. I graduated from Virginia-Maryland Regional College of Veterinary Medicine in 2007. Since then I have been practicing small animal medicine in the greater Denver area. General practice has two very important parts. One is treating the animal in the best way possible. This can range from running tests to performing surgery to prescribing medications. The second is to preserve the bond between the pet and their person. This means establishing a relationship with not only the pet, but also their owner so we can make the best possible decision for their pet.

Apart from veterinary medicine, I enjoy all things outdoors. This includes mountain biking, road biking, running, hiking, and camping. I share a home with my husband and daughter, and four dogs (Dixie, Zipp, Naners, and Cricket).

Krista Ferndelli

Chief Connections Officer

I grew up in central Minnesota in a (quite sadly) pet-less household, even though there was no end to my requests to have animals! As soon as I moved out, I rectified that situation, and got a cat. Through almost two decades of experiences personally taking my pet to multiple veterinary practices since that time, I have learned that the right guidance and advice, an understanding of where I was coming from in my life, and honest communication without judgement was critical for me and my family in making the best decisions possible for our pets and our household. That household has grown to include a husband, 11 year old son and 8 year old daughter, who loved that cat (and continue to love all animals) as much as I. We all love taking our dog, Cayenne, out to experience the beauty of Colorado for bike rides, runs, mountain hikes, and to local breweries and baseball games.

My experience with Golden Paws – as a customer first – has been the easiest, best, most straightforward, and comfortable one for my family yet. I bring a degree in Communication from the University of Minnesota, Duluth, more than 15 years of strategic marketing, communications, and public relations accuity, and my passion for pets to Golden Paws. It is my personal mission to help ensure we deliver Golden Paws’ unique quality veterinarian partnership to many more households in our local community. Because both people and pets deserve it.


Certified Veterinary Technician

Ever since I was young growing up in Salt Lake City, I have been drawn to animals and wanted to find a career in which I could contribute to their well-being. I graduated from Utah State University with a Bachelor of Science in Forestry. After several years in the workforce, I decided to attend Bel-Rea Institute of Animal Technology in Denver to become a Certified Veterinary Technician. After completing my studies, I worked for a short time in Washington State in a small animal hospital. Missing Colorado, I returned and worked for a busy small animal practice for the past eleven years. The greatest joy I find as a technician is seeing our animal family members reunite with their loved ones after recovering from an illness. In my spare time, I enjoy hiking, golfing, spending time with family and friends, my little Schnauzer Joe and flying my RC airplanes. I am very excited to work with Dr. Sam and to be part of the team at Golden Paws Animal Hospital.

She fell in love with the dogs, switched to grooming school with Animal Behavioral College, and never looked back. After completing her training, she continued to work for the boarding facility while also working at the local Humane Society as a groomer. Upon moving to Golden in 2016, she began work as a full-time groomer. She currently lives with her fiancé and has two standard Poodles, an old Lab, and a cat. She specializes in haircuts for dogs with curly coats, but does well with all breeds.

Katie Gregory


I have lived in Colorado since I was a kid, and have always loved animals. I grew up with dogs and horses, and knew very early on that I wanted to spend the rest of my life working with them in some capacity. My career thus far has been in private practice veterinary clinics, as well as a local 24-hour emergency hospital. In my spare time, I enjoy spending as much time with my family and friends as possible. I have a senior dog named Cooper, and I am entertaining the thought of getting him a new brother soon!

Cortney Dixon

Receptionist & Office Manager

Originally from Seattle Washington, I have lived in Colorado for 6 years. After working in the spa/hospitality field as a director of spa and fitness and running logistics for a personal growth and development training company, I realized my calling was working in veterinary medicine. I have always loved anything and everything about animals and have been working in the field for about 5 years. The opportunity to work in one of the largest veterinary hospitals in the Colorado area for 3 years allowed me to learn and specialize in the emergency vet side of medicine. My experience supervising and having hands-on time with the animals has given me the best of both worlds, utilising my skills for both pets and owners. In my free time I enjoy being with “my boy” Leonidas, my American Bulldog mix.
