--Varduhi K.

Dr. Gregory Tennant is my saving grace. I had a terrible back injury & he's been patching me up since the first time he saw me. No other doctor would help me & most asked me what I wanted to do to fix the issue... Saw Dr. Gregory Tennant twice already and both visits had immediate recommendations/solutions that actually got me back to my working self. God bless the doctor and the amazing staff here for all the support 🙏 It is all most appreciated.

--Kimberly E.

Dr. Tennant took care of my broken leg when I was admitted to Antelope Valley Hospital. He's extremely nice and professional and did a great job on my leg. When I went to the office for follow up everyone was over-the-top nice and friendly, professional and helpful. The only problem I had there was the wait time. The waiting room was s packed with people waiting to be seen. There are several doctors in the practice and the number of people in the waiting room was a little disconcerting. Other than that everything was great! Thank you Doctor Tenant!


--Sue P.

Even though I  got confused on stuff I was able with the help of personnel to figure it out. Dr. Tennant is terrific! So glad he was my doctor. I had complete trust in him from beginning to surgery and even now. Thank you for your caring, kind group of employees that work at AVORS! 😁💯

Avors Medical Group has a very efficient staff. They are always eager to be helpful, kind able to answer even silly questions.
The Dr's are top notch. They get as much information as they can from you with the goal of getting you feeling better fast. I saw a Dr. Tennant this week. He was great.


--Aaron S.

Great first-time experience. Doctor was very thorough and forthcoming.


--Yolanda W.

I was amazed by how fast I was given an appointment. Walked to the reception, everything was bright. The chairs are all new. I'm mention the chairs because I have osteoarthritis and have a difficult time standing up from low chairs. These chairs are high, enough to sit and stand up with ease. I was called back to the exam room with in ten minutes. Once in, the Doctor came in with in 5 minutes. He was very nice and explained everything to me. I was very pleased with my visit.

-Charles F.

I was treated with the upmost care and concern each and every time I interacted with not only the medical staff within the office setting but my surgeon as well…I would highly recommend Avor’s to anyone especially those who have fear of medical professionals…they took time to speak with me answering any and all questions I’ve had (and there have been many) which allowed me to remain calm and fearless going into separate two surgeries to fix my once severely dislocated broken bones…my surgeon always has a smile on his face and the skills he possesses are incredible! I am now able to use my arm again and only have a thin scar left as a reminder of the painful incident I endured… should I ever find myself needing another procedure done on my arm or other body part they specialize in I will definitely call upon them again ☺️ Thank you Dr. Tennant and all the wonderful staff that works alongside you…you’ve made a huge impact in my life and I’ll be forever grateful!!!

I was well informed of everything that was going to happen with the surgery. They treated me amazing and made sure I had everything I would need for a smooth, speedy recovery. Definitely top notch!


--Angela W.

Dr Tennant is one of the top doctors I've been to. He is one of the first that listen to what I have to say, then offer the options of treatment that would benefit me. It was nice for ME to be in charge of treatment. The office staff and medical assistants are always super friendly and welcoming every visit.


--Jeremy J.

"Dr. Tennant did my emergency surgery when I came in ER for a compound fracture injury back in November 2022. He is now my orthopedic doctor at Avors medical group. I don't trust anyone else but Dr. Tennant to treat my broken bones. The staff is really professional and kind. They have a large waiting area to accommodate wheelchairs so you don't feel like packed sardines. I have a long recovery ahead of me. The doctor and staffs are kind and understanding so I definitely would recommend this practice to anyone."
