Theisz Gordon W MD

Dr. Theisz has been my primary care doctor for years. What I love most is he knows his patients. His office doesn’t double book therefore there is very little waiting time moving from the front to an exam room. I never feel rushed, he answers all my questions in a patient, caring manner. He is friendly and has a great since of humor!!!

Dr. Theisz was my primary care physician for over a decade, until I moved out of Virginia. Without a doubt, Dr. Theisz is the most attentive, compassionate and flexible healthcare professional I have ever trusted with my health. He looked after me over the years, through various health challenges, and I never once felt like just another name on the list for him to deal with. I’d say his best quality is his bedside manner/communication. Thank you.

Dr. Theisz was my primary care doctor since my family moved here in 2008 from Kansas until I relocated again to Maui, Hi last year 2019.
He is very professional , caring and an excellent doctor. How I wish he is still my primary care physician but due to my relocation, it was not possible. I wish to thank him and his staff especially Ms. Thomasina who has been helpful and attentive whenever I need assistance in prescription requests and appointments.

Dr. Theisz is absolutely top notch. The spouse and I have been seeing him for over a dozen years. He is professional, yet friendly and caring, which puts me at ease and I can be frank and open about anything bothering me. Another great aspect about this well-established practice is that, I feel, I have access to the absolute best health care around. For example: remember the bird flu / swine flu scare years back? Well, Dr. Theisz managed to obtain vaccines and held a clinic for patients during the shortage and height of it all. I was very thankful, since I was leaving to travel abroad. The place is well staffed and everyone is friendly. Parking isn't an issue. They are open longer hours than other places. Overall a great facility.

I cannot express how much I appreciate Dr. Theisz's care for my son and myself over the last few years. He is a great family doctor in his demeanor, and he absolutely nailed a few diagnoses for things that were definitely not obvious to us. His referrals to other physicians were spot on.

In my travels, I've told people what a great family Dr we have in him and one of my biggest regrets in moving away will be not having Dr. Theisz as our family physician. Thank You Dr. T!!!

Dr. Theiz is our family doctor since we moved from CA to VA, 7+ years ago. With big surprise I have read 2 low rated reviews since he is one of the most caring, understanding, thorough doctors I have ever met in my life. He does listen, he is an excellent diagnostician and besides all that, he is friendly, caring, understanding, and patient, and he remembers his patients. I have referred him to a few of my friends and all of them are very happy and have no complaints, only praise. I personally do not have insurance and have to pay for all services. Not only are his rates reasonable, his staff will also try to find the least expensive place if you need X-rays, MRI or else. He will also try to prescribe the least expensive medication, often giving samples of drugs that are high priced at pharmacies. Time spent waiting for your appointment is minimal after you check in and if you are an existing client you will get an appointment real fast.
Overall, we consider ourselves lucky to have found him.

Great physician. Caring and patient, Dr. Theisz is not the typical "in and out" doctor that is so prevalent today. He spends the time necessary to make a proper diagnosis and to inform the patient. From the moment he warmly greets you by name and shakes your hand, to the "always glad to see you, take care" good bye, one feels like there is no other patient as important to Dr. Theisz than themselves.

Dr. Theisz is a great doctor, highly recommend! I've been seeing him about 6 or 7 years now. My husband and I used to live right down the street from his practice and have since moved to Reston and now Leesburg. I like him so much I still drive the distance. Finding a doctor you like and trust is hard to come by. Great bedside manor and he cares.

Dr. Theisz is the primary for our entire family and does a wonderful job. Whenever we need him he is there and his office staff is more than accommodating, even on short notice. I feel that they actually care about us and they remember us by name. We have moved an hour away and still drive to see him where previously he was 5 minutes away. It’s worth it.

We recently switched to Dr. Theisz from Northern Virginia Pediatrics. I wanted a whole family doctor and also something more personal. NVA Pediatrics has great doctors but the practice is huge and annuals have to be planned 1 year in advance etc. We have received great and quick service at Dr Theisz’s office, quality medical care and just enjoy the process more.

I can't even find the words to express my admiration for this doctor. He is very professional but also has a great sense of humor. He is willing to try and find the problem and will listen as you state your concerns. He is not just the I will write a perscription for that type of doctor. I have referred him to my coworkers, friends and family. People who know me say, I am hard to please so this means a lot coming from me. Thanks Dr. Theisz for being wonderful and making every visit seem like I am the only patient you have in your very busy office. :)

Dr. Theisz is wonderful! He was a good listener, knowledgeable, friendly and down to earth. He made me feel very comfortable during my visit. Thank you!

Great day-of COVID testing. Wasn't even a patient, called at 6:30pm and got an appointment for 7:30pm. Nurse was polite and professional, test was administered outdoors. Stay safe, yall

Super friendly and knowledgeable GP. I have been going to him for 10 years and am always happy with the time he takes at each visit and the guidance he provides has been spot-on!

Dr. Theuisz is a great doctor. Friendly and very helpful.

The wait times are long but Dr. Theisz is a wonderful doctor, incredibly friendly and efficient. I can't recommend him highly enough.
